How to Move Files from Dropbox to Backblaze B2

Move files from Dropbox to Backblaze B2 with Blober

Why People Leave Dropbox for Backblaze B2

Section titled "Why People Leave Dropbox for Backblaze B2"

Dropbox works well as a file sync tool. You drop files in a folder and they show up on all your devices. But as your data grows, Dropbox gets expensive. The Plus plan costs $120/year for 2 TB. If you have 5 TB or more, you need Dropbox Business at $180/year per user.

Backblaze B2 charges $6.95 per TB per month for storage. For 2 TB, that is about $14/month or $167/year. But here is where it gets interesting: most of the data sitting in Dropbox is not being actively synced. It is old projects, archives, backups, photos from three years ago. That data does not need instant sync to every device. It needs to be stored cheaply and retrieved when needed.

For archival and backup storage, Backblaze B2 is significantly cheaper. And unlike Dropbox, you only pay for what you use. No fixed plans, no storage ceilings.

The Problem with Moving Data Out of Dropbox

Section titled "The Problem with Moving Data Out of Dropbox"

The obvious approach is to download everything from Dropbox to your computer, then upload it to Backblaze B2. This works for small amounts of data. For 500 GB or more, it becomes painful:

  • You need enough free space on your local disk to hold the download
  • Downloading takes hours or days depending on your connection
  • Uploading to B2 takes equally long
  • If anything fails midway, you start over

Some people try rclone for this. rclone works, but you need to configure both remotes in a text file, understand the command syntax, and handle errors yourself. If you are comfortable with the terminal, rclone is a solid choice. If you are not, it is a wall.

How to Transfer with Blober

Section titled "How to Transfer with Blober"

Blober connects to both Dropbox and Backblaze B2. You set up both providers, select the files you want to move, and Blober handles the transfer. Files stream from Dropbox through your computer to Backblaze B2 without needing to store them locally.

Step 1: Connect Dropbox

Section titled "Step 1: Connect Dropbox"

Add Dropbox as a provider in Blober. Click the OAuth login button and authorize Blober with your Dropbox account. Blober stores your credentials locally on your machine, not on any server.

Step 2: Connect Backblaze B2

Section titled "Step 2: Connect Backblaze B2"

Add Backblaze B2 as a provider. You will need your Application Key ID and Application Key from the Backblaze dashboard. Blober verifies the connection and lists your buckets.

Step 3: Create a Workflow

Section titled "Step 3: Create a Workflow"

Create a new workflow with Dropbox as the source and Backblaze B2 as the destination. Browse your Dropbox files, select what you want to transfer, and choose which B2 bucket to send it to.

Step 4: Run

Section titled "Step 4: Run"

Click run. Blober transfers files with parallel uploads, progress tracking, and automatic resume if your connection drops.

What About Folder Structure?

Section titled "What About Folder Structure?"

Blober preserves your folder structure. If you have Projects/2024/Client-A/ in Dropbox, it creates the same path in your B2 bucket. You do not end up with a flat pile of files.

Cost Comparison

Section titled "Cost Comparison"
Dropbox PlusBackblaze B2 (2 TB)
Monthly cost$10/month~$14/month
5 TBNeed Business plan ($15/user/mo)~$35/month
10 TBNeed Business plan~$70/month
EgressFree (sync)Free to Cloudflare partners, $0.01/GB otherwise
API accessOAuthS3-compatible

For pure storage (not sync), B2 wins at every tier above 2 TB. And if you pair B2 with Cloudflare CDN through the Bandwidth Alliance, egress is free.

When to Keep Dropbox

Section titled "When to Keep Dropbox"

This is not about abandoning Dropbox entirely. Dropbox is great for active files you need on every device. The move that makes sense for most people is:

  • Keep Dropbox for current projects and actively used files
  • Move archives, old projects, and large media to Backblaze B2
  • Use Blober to transfer the archival data once, then cancel the upgraded Dropbox plan

How to Move Files from Dropbox to Google Drive

Move files from Dropbox to Google Drive with Blober

Move Dropbox to Google Drive Without Filling Your Disk

Section titled "Move Dropbox to Google Drive Without Filling Your Disk"

The problem: there is no built-in transfer between Dropbox and Google Drive. The manual route makes you download your entire Dropbox to your computer, then upload all of it to Drive. That needs free disk space equal to your whole library and sends every file over the network twice.

The short answer: you have three realistic options. Drag and drop through the desktop apps, upload through the browser, or run a direct cloud-to-cloud transfer with Blober that streams each file from Dropbox to Google Drive without saving it to your disk. Here is how they compare.

MethodLocal disk neededSpeedFolder structureBest for
Manual (desktop sync, then drag)Full library sizeSlow: download, then uploadYou may have to rebuild itA single small folder
Browser uploadEnough to download firstSlowPreserved if you recreate foldersA few gigabytes
Blober (direct)None, files stream through memoryAbout half the time, single passPreserved automaticallyWhole-account moves and large libraries

People switch from Dropbox to Google Drive for a few common reasons:

  • Their company standardized on Google Workspace and needs everything in Drive
  • Google One pricing is more competitive for their storage needs (2 TB for $100/year vs Dropbox Plus at $120/year)
  • They want the Google Docs, Sheets, and Slides collaboration features
  • They are consolidating everything under one Google account

The actual move is where friction shows up.

The Manual Way

Section titled "The Manual Way"

Without a migration tool, moving from Dropbox to Google Drive looks like this:

  1. Install the Dropbox desktop client
  2. Wait for all files to sync to your computer
  3. Drag those files into your Google Drive folder (if using the desktop client) or upload them through the browser
  4. Wait for everything to upload
  5. Verify nothing was missed

This requires enough local disk space to hold your entire Dropbox. If you have 500 GB in Dropbox and a 256 GB laptop, you are stuck.

Even with enough space, the process is slow. You are downloading everything from Dropbox's servers to your local disk, then uploading everything from your local disk to Google's servers. That is double the transfer time.

How Blober Does It

Section titled "How Blober Does It"

Blober connects to both Dropbox and Google Drive. Files stream from Dropbox through your computer to Google Drive without being stored on your local disk. You need just enough memory to buffer the current file being transferred, not enough disk space for your entire library.

What This Means Practically

Section titled "What This Means Practically"
  • No disk space worries. A 1 TB Dropbox migrates to Google Drive even on a laptop with 128 GB of storage.
  • Half the network time. Instead of download + upload (two trips), Blober streams the data through in a single pass. The download from Dropbox and upload to Google Drive happen simultaneously.
  • Folder structure preserved. Your Dropbox folder hierarchy recreates exactly in Google Drive.

Steps

Section titled "Steps"
  1. Connect Dropbox: OAuth login in your browser. Blober supports both long-term OAuth tokens (with refresh) and direct access tokens.
  2. Connect Google Drive: OAuth login in your browser. Blober accesses your Drive files.
  3. Browse and select: Navigate your Dropbox in Blober's file browser. Select specific folders or your entire Dropbox.
  4. Create a workflow: Set Dropbox as source, Google Drive as destination.
  5. Run: Blober transfers with auto-resume and progress tracking.

Moving your whole Dropbox? Blober streams it straight into Google Drive without filling your laptop. Download Blober, connect both accounts, and start the transfer.

Copy and Move Support

Section titled "Copy and Move Support"

Dropbox is one of the providers where Blober supports native copy and move operations. This means:

  • Copy duplicates files within Dropbox without re-downloading them
  • Move relocates files within Dropbox without a round-trip transfer

For the cross-cloud transfer to Google Drive, files stream through your machine as described above. But if you also need to reorganize files within Dropbox before or after the migration, Blober handles that natively.

After the Migration

Section titled "After the Migration"

Once your files are in Google Drive:

  • They are accessible from any device with a Google account
  • Google automatically indexes content for search
  • Office files (DOCX, XLSX, PPTX) can be edited natively in Google Docs/Sheets/Slides
  • Files sync across devices via the Google Drive desktop app

You can keep Dropbox installed alongside Google Drive if you need a transition period. Once you verify everything transferred correctly, you can downgrade or cancel Dropbox.

Frequently Asked Questions

Section titled "Frequently Asked Questions"

Can I transfer files from Dropbox to Google Drive without downloading them first? Yes. Blober streams each file directly from Dropbox to Google Drive through your computer. Nothing is saved to your local disk, so you do not need free space equal to your library size.

Does Blober preserve my Dropbox folder structure in Google Drive? Yes. Your Dropbox folder hierarchy is recreated exactly in Google Drive, including nested folders.

How long does a Dropbox to Google Drive migration take? It depends on how much data you have and your upload speed. Because Blober downloads and uploads in a single pass instead of two separate trips, it finishes in roughly half the time of a manual download-then-upload.

Can I sync Dropbox to Google Drive automatically? Blober moves and copies files on demand through workflows that you start when you need them. You can re-run a workflow at any time to move newly added files. It is built for migrations and repeat transfers rather than always-on background sync.

Can I move from Dropbox to Google Workspace or a Shared Drive? Yes. Google Workspace accounts and Shared Drives appear in Blober once you connect Google Drive, so you can set either as the destination.

One Move, Not a Monthly Bill

Section titled "One Move, Not a Monthly Bill"

Most cloud-to-cloud services bill per gigabyte or charge a monthly fee for as long as you keep them. Blober is a one-time purchase. Moving 50 GB costs the same as moving 5 TB, and there is nothing to cancel once the migration is done. For a one-off move from Dropbox to Google Drive, that is the difference between paying once and renting a tool for a weekend.

How to Switch from Google Drive to Dropbox

Switch from Google Drive to Dropbox with Blober

Move Google Drive to Dropbox Without the Google Docs Trap

Section titled "Move Google Drive to Dropbox Without the Google Docs Trap"

The problem: Google Docs, Sheets, and Slides are not real files. They live only inside Google, so you cannot drag them into Dropbox, and Google Takeout exports your library as flat date-stamped zips that lose your folder names.

The short answer: you have three realistic options. Export each native file by hand, use Google Takeout and reorganize the zips afterward, or run a direct transfer with Blober that converts Google Docs to Office formats and rebuilds your folders in Dropbox automatically. Here is how they compare.

MethodGoogle Docs handlingFolder structureLocal disk neededBest for
Manual export, then uploadOpen and export each oneRebuild by handFull library sizeA handful of files
Google TakeoutExports to Office, inside flat zipsLost in date-stamped foldersSpace for every zipA full archive you will sort later
Blober (direct)Auto-converts to .docx, .xlsx, .pptxPreserved automaticallyNone, files stream through memoryMoving your account intact

Google Drive vs Dropbox: Different Strengths

Section titled "Google Drive vs Dropbox: Different Strengths"

Google Drive is tightly integrated with Google Workspace. If your team lives in Gmail and Google Docs, Drive is the natural file storage. But if you work with non-Google tools, or you need reliable desktop sync, offline access, and smart file management, Dropbox has a stronger desktop experience.

People switch from Google Drive to Dropbox for a few reasons:

  • Dropbox's desktop sync is more reliable for large file sets
  • Better support for non-Google file formats and creative tools
  • Dropbox Paper, Smart Sync, and team folder management
  • Moving away from Google Workspace entirely

Whatever the reason, the migration is the part nobody looks forward to.

Why the Switch Is Harder Than It Sounds

Section titled "Why the Switch Is Harder Than It Sounds"

Google Drive stores some files as native Google formats. Google Docs, Sheets, and Slides are not files in the traditional sense. They exist only in Google's cloud. You cannot drag a Google Doc into Dropbox.

If you try to move files manually, you need to:

  1. Open each Google Doc, Sheet, or Slide
  2. Download it as DOCX, XLSX, or PPTX
  3. Upload it to Dropbox
  4. Repeat for every native Google file

For regular files (PDFs, images, videos), you download from Google Drive and upload to Dropbox. But you still need enough local disk space to hold everything, and you need to recreate the folder structure manually.

Google Takeout exports everything as flat zip archives. Your carefully organized folder structure disappears into date-stamped directories.

How Blober Makes This Painless

Section titled "How Blober Makes This Painless"

Blober connects to both Google Drive and Dropbox. When it encounters Google Docs, Sheets, or Slides, it automatically converts them to their Office equivalents (DOCX, XLSX, PPTX) during the transfer. Regular files pass through as-is.

What You Get

Section titled "What You Get"
  • Google Docs become .docx files that open in Word, Dropbox Paper, or any text editor
  • Google Sheets become .xlsx files that open in Excel or Numbers
  • Google Slides become .pptx files that open in PowerPoint or Keynote
  • Regular files (PDFs, images, videos) transfer without conversion
  • Folder structure preserved exactly as it appears in Google Drive
  • Shared files accessible through the "Shared with me" virtual folder

Steps

Section titled "Steps"
  1. Connect Google Drive: OAuth login through your browser
  2. Connect Dropbox: OAuth login (or paste an access token)
  3. Browse and select: Navigate your Google Drive in Blober's file browser, select everything or specific folders
  4. Run the transfer: Files move from Google Drive to Dropbox through your computer

No local disk space needed for intermediate storage. Blober streams files directly from one cloud to the other.

Leaving Google Drive? Blober converts your Docs to Office files and rebuilds your folders in Dropbox in one pass. Download Blober, connect both accounts, and run it.

After the Switch

Section titled "After the Switch"

Once your files are in Dropbox, you can:

  • Install Dropbox on your devices for desktop sync
  • Share folders and files with Dropbox's sharing tools
  • Use Smart Sync to keep files in the cloud until you need them locally
  • Edit Office files directly (Dropbox has built-in Office integration)

The converted Google Docs are fully editable Office files. They are not locked into any format.

Frequently Asked Questions

Section titled "Frequently Asked Questions"

Can I move Google Drive to Dropbox without downloading everything first? Yes. Blober streams files directly from Google Drive to Dropbox through your computer, so you do not need local disk space for the whole library.

What happens to my Google Docs, Sheets, and Slides? Blober converts them automatically during the transfer. Docs become .docx, Sheets become .xlsx, and Slides become .pptx, all fully editable in Office, Dropbox Paper, or similar tools.

Does Blober transfer files shared with me? Yes. Files shared with your Google account appear under the "Shared with me" folder in Blober and can be included in the transfer.

Can I sync Google Drive to Dropbox automatically? Blober transfers files on demand through workflows that you run when you need them, and you can re-run a workflow to move new files. It is designed for migrations and repeat transfers rather than continuous background sync.

Can I switch from Google Workspace or a Shared Drive to Dropbox? Yes. Workspace accounts and Shared Drives show up in Blober after you connect Google Drive, so you can use either as the source.

How to Switch from Wasabi to Backblaze B2

Switch from Wasabi to Backblaze B2 with Blober

Two S3-Compatible Providers, Different Tradeoffs

Section titled "Two S3-Compatible Providers, Different Tradeoffs"

Wasabi and Backblaze B2 both position themselves as affordable alternatives to AWS S3. Both are S3-compatible. Both offer low-cost storage. But they have meaningful differences that lead people to switch from one to the other.

Wasabi's Model

Section titled "Wasabi's Model"

Wasabi charges $6.99/TB/month with no egress fees. Sounds perfect, until you read the fine print:

  • 90-day minimum retention. If you delete or overwrite a file within 90 days, you still pay for the full 90 days of storage.
  • Egress is "free" with conditions. Your monthly egress cannot exceed your stored data. If you store 1 TB and download 1.5 TB in a month, Wasabi may contact you about their "reasonable use" policy.
  • No native CDN partnerships. Wasabi does not have bandwidth alliance partnerships like Backblaze does.

Backblaze B2's Model

Section titled "Backblaze B2's Model"

Backblaze B2 charges $6.95/TB/month for storage and $0.01/GB for egress. But:

  • Free egress through Cloudflare. Through the Bandwidth Alliance, egress from B2 to Cloudflare is free. If you use Cloudflare as your CDN (many do), egress is effectively $0.
  • No minimum retention. Store and delete whenever you want.
  • Free egress allowance. B2 includes 3x your storage amount in free egress each month. If you store 1 TB, you get 3 TB of free downloads.

For most use cases, Backblaze B2 ends up cheaper or equivalent to Wasabi, with fewer restrictions.

Moving the Data

Section titled "Moving the Data"

Both Wasabi and Backblaze B2 speak the S3 protocol. This means Blober uses the same underlying S3 operations for both providers, making the transfer clean and predictable.

Steps

Section titled "Steps"
  1. Connect Wasabi: Add Wasabi as a provider with your Access Key, Secret Key, and region (Wasabi uses region-specific endpoints like s3.us-east-1.wasabisys.com).
  2. Connect Backblaze B2: Add B2 with your Application Key ID and Application Key. Blober auto-detects your bucket regions.
  3. Create a workflow: Source = Wasabi, Destination = B2. Browse your Wasabi buckets, select what to move.
  4. Run: Blober transfers with parallel multipart uploads and automatic resume.

What Blober Handles

Section titled "What Blober Handles"
  • Multi-region detection for B2. Backblaze B2 buckets can be in different regions. Blober fetches all buckets via B2's native API to determine the correct region for each, then configures the S3 endpoint accordingly.
  • Region-aware endpoints for Wasabi. Wasabi uses different endpoints per region. Blober maps your chosen region to the correct endpoint.
  • Large file support. Both providers handle multipart uploads. Blober chunks large files and uploads them in parallel.

Watch the 90-Day Window

Section titled "Watch the 90-Day Window"

When migrating from Wasabi, keep in mind the 90-day minimum retention policy. If you uploaded files to Wasabi less than 90 days ago, you will be charged for the full 90 days even after you delete them.

The practical approach:

  1. Transfer everything to Backblaze B2
  2. Wait until the oldest files in Wasabi pass the 90-day mark
  3. Then delete and close the Wasabi account

This avoids paying both Wasabi and B2 for the same data longer than necessary.

How to Transfer Files from AWS S3 to Azure Blob Storage

Transfer files from AWS S3 to Azure Blob Storage with Blober

Moving Between the Two Largest Cloud Providers

Section titled "Moving Between the Two Largest Cloud Providers"

AWS S3 and Azure Blob Storage are the two most popular object storage services in the world. Companies move data between them for all sorts of reasons: switching primary cloud vendors, setting up multi-cloud redundancy, following compliance requirements, or simply taking advantage of Azure's pricing for certain workloads.

The transfer itself is the hard part. Both providers have their own tools (AWS DataSync, Azure Data Box, AzCopy), but those tools are designed for their own ecosystem. Cross-cloud transfers with native tools usually require intermediate steps, scripting, or third-party managed services that charge per-GB.

The Usual Approaches

Section titled "The Usual Approaches"

AzCopy + AWS CLI

Section titled "AzCopy + AWS CLI"

You can download from S3 using the AWS CLI and upload to Azure using AzCopy. This requires local disk space for the intermediate files, separate authentication for each tool, and scripting to coordinate the two.

Managed Migration Services

Section titled "Managed Migration Services"

Services like Flexify charge per-GiB transferred. For large migrations (10 TB+), the fees add up. Your data also routes through their infrastructure, which may not meet compliance requirements.

rclone

Section titled "rclone"

rclone supports both S3 and Azure Blob. It works, but you need to configure both remotes, handle multipart upload settings, and manage the transfer from the command line.

How Blober Handles It

Section titled "How Blober Handles It"

Blober connects to both AWS S3 and Azure Blob Storage natively. You configure both providers with their respective credentials, create a workflow, and run the transfer. Files stream from S3 through your machine to Azure without intermediate storage.

What Blober Does That Matters for This Transfer

Section titled "What Blober Does That Matters for This Transfer"

Parallel uploads to Azure. Blober uses Azure's uploadStream with configurable concurrency. Large files are streamed in parallel chunks, which makes a noticeable difference on fast connections.

S3 multipart downloads. On the source side, Blober downloads from S3 using the AWS SDK with multipart support. Large objects do not bottleneck the pipeline.

Azure tier selection. When setting up Azure as your destination, you choose which storage tier new blobs land on: Hot, Cool, Cold, or Archive. This means you can migrate directly to the tier that matches your access pattern without a second step to change tiers after upload.

Write behavior options. You can configure Blober to overwrite existing blobs, skip files that already exist at the destination, or skip only archived blobs. This is useful for incremental migrations where you want to resume without re-transferring what is already there.

Step-by-Step

Section titled "Step-by-Step"
  1. Connect AWS S3: Add S3 as a provider with your Access Key ID, Secret Access Key, and region. Blober lists your buckets.
  2. Connect Azure Blob: Add Azure Blob Storage with your connection string. Blober verifies and lists your containers.
  3. Create a workflow: Set S3 as source, Azure Blob as destination. Browse and select files or entire buckets.
  4. Choose Azure options: Pick the storage tier and write behavior.
  5. Run: Blober transfers with progress tracking and auto-resume.

Migrating Buckets in Bulk

Section titled "Migrating Buckets in Bulk"

Most S3-to-Azure jobs are not a single file, they are whole buckets or whole prefixes. Blober is built for that.

  • Select an entire bucket or prefix. Browse your S3 bucket in Blober, select everything at the top level or drill into a prefix, and queue it all in one workflow. You do not enumerate keys by hand or script a loop.
  • Mass transfers run in parallel. Blober downloads from S3 with multipart support and uploads to Azure with parallel streams, so a bucket with thousands of objects moves as a continuous pipeline rather than one object at a time.
  • Resumable with skip-existing. Set the write behavior to skip blobs that already exist at the destination. If a multi-terabyte run is interrupted, or you stop and continue tomorrow, re-running the workflow picks up only what has not transferred yet. That is what makes a mass migration practical: you are never forced to start over.
  • Land directly on the right tier. Pick the Azure tier for the whole job, so a bulk archive migration writes straight to Cool, Cold, or Archive instead of landing on Hot and needing a second pass.

For a move of 5 TB across 200,000 objects from us-east-1 to westeurope, you point Blober at the bucket, choose the destination container and tier, turn on skip-existing, and let it run. Progress is tracked per file, and the run survives a dropped connection.

Cross-Region Awareness

Section titled "Cross-Region Awareness"

If your S3 bucket is in us-east-1 and your Azure storage account is in westeurope, Blober handles the cross-region transfer. S3's cross-region copy limitations (which affect native S3-to-S3 copies) do not apply here because the data flows through your machine.

The tradeoff is that transfer speed depends on your internet connection. For very large migrations (50 TB+), this is slower than a datacenter-to-datacenter transfer. But for migrations under 10 TB, running through Blober on a fast connection is often faster than coordinating managed services.

Pricing Comparison

Section titled "Pricing Comparison"
AWS S3 StandardAzure Blob HotAzure Blob Cool
Storage (per TB/mo)$23$18$10
Egress (per GB)$0.09$0.087$0.087
PUT requests (per 10K)$0.005$0.065$0.10

Azure is generally cheaper for storage. S3 is cheaper for write-heavy workloads. The right choice depends on your access patterns.

Frequently Asked Questions

Section titled "Frequently Asked Questions"

How do I copy data from S3 to Azure Blob without AzCopy or scripts? Connect both providers in Blober, create a workflow with S3 as the source and Azure Blob as the destination, select your buckets, and run. There is no AzCopy command, no AWS CLI loop, and no intermediate download to your disk. Files stream from S3 straight to Azure.

Can I migrate a whole bucket, or only individual files? Either. Select a single object, a prefix, or an entire bucket. Whole-bucket and mass-data migrations are the common case.

Does the data land on the tier I want? Yes. You choose the Azure access tier (Hot, Cool, Cold, or Archive) for the destination, and new blobs are written to that tier on arrival. There is no second pass to re-tier after upload.

Who pays for the data transfer? AWS charges egress (data transfer out) when data leaves S3, billed per GB. Azure does not charge to ingest. So the transfer cost sits on the AWS side, the same as it would with any tool that reads from S3. Blober adds no per-GB fee of its own.

How large a migration can this handle? Transfers run through your machine, so speed depends on your connection. For migrations up to roughly 10 TB on a fast link, running Blober is often faster than setting up a managed service. For datacenter-scale moves of 50 TB and up, a provider appliance may finish sooner, but Blober still works and resumes if interrupted.
