BloberCloud transfer
Move files from Amazon S3 to Azure Blob Storage
S3 to Azure is usually a cost or compliance move, and it is where scripts get abandoned. Blober copies bucket to container and reports what landed, without PowerShell or AzCopy.
How the transfer works
Three steps between Amazon S3 and Azure Blob Storage.
- 1
Connect Amazon S3 and Azure Blob Storage
Add both accounts in Blober and sign in on your own machine. Credentials stay local; nothing is proxied through a server.
- 2
Choose what moves
Browse Amazon S3, filter by folder, date or type, then set the folder it should land in on Azure Blob Storage.
- 3
Start and walk away
Blober runs transfers in parallel, resumes after a dropped connection, and reports every file it moved.
Both ends, connected properly
Managed accounts, not a shared folder and not a workaround.
Source
Amazon S3
Amazon S3 is the object store most other services are measured against. Blober moves data in and out of buckets without AzCopy-style scripts.
Destination
Azure Blob Storage
Azure Blob Storage is Microsoft’s object store. Its tiers trade retrieval time for price, which is what makes bulk tier changes and long-term archives worth doing in one run.
Why move files from Amazon S3 to Azure Blob Storage with Blober
Cloud-to-cloud copying without a server in the middle, a script to maintain, or a per-gigabyte bill.
- No download and re-upload
- Files stream between the two accounts, so the library never has to fit on your disk first.
- One-time licence
- No per-transfer fees and no storage tiers of its own, just the price of the app.
- Resumable by default
- A dropped connection pauses the run instead of restarting it, and failed files retry.
- Credentials stay local
- Blober talks to both providers from your machine, so your logins are never held elsewhere.
Amazon S3 to Azure Blob Storage: questions
What people ask before moving files between these two.
How do I move files from Amazon S3 to Azure Blob Storage?
Install Blober for desktop, connect both accounts, choose Amazon S3 as the source and Azure Blob Storage as the destination, then start the transfer. Blober lists what it can see first, so you can pick folders before anything moves.
Can I transfer from Amazon S3 to Azure Blob Storage without downloading the files?
Yes. Blober streams each file from Amazon S3 to Azure Blob Storage instead of saving it to your disk and uploading it again. You do not need the free space, and nothing is left behind in a temporary folder.
Is there a file size or transfer limit?
No. Blober does not cap file size, file count or total volume, and it does not charge per transfer. The only limits are the ones your Amazon S3 and Azure Blob Storage plans already have.
What happens if the connection drops part way through?
Blober resumes. It retries failed files and continues from where it stopped, so a long migration does not have to start again from zero.
Are the folders and file names preserved?
Yes. Blober recreates the source structure at the destination. You can also apply a path template to sort files by date, type or size as they land, which helps when the source is a camera roll rather than a tidy folder tree.
Does my computer need to stay on?
Yes. Blober is a desktop app, so the transfer runs on your machine between your two accounts. That is also why your credentials never leave it.
How much does Blober cost?
Blober is a one-time licence, not a subscription. There are no per-transfer fees and no storage tiers of its own: you pay once, and every provider is included.
Do I need to run AzCopy first?
No. AzCopy is a command-line tool that has to be installed, scripted and re-run after failures. Blober does the same copy with a source, a destination and a start button.
Can I land the data in the Azure Archive tier?
Yes. Azure Archive is for data that is written once and read rarely, so Blober writes there and reports back. Remember that reading it again needs a rehydration job and up to 15 hours.
