Verdict: No
No. Backblaze Computer Backup is offered for Windows and Mac only. There is no Linux version of the backup app, so your subscription stops being useful the day you switch.
Backblaze's own Computer Backup pages offer a download for Mac and a download for PC, and describe the software as native Mac and Windows clients. Linux is not listed and there is no installer.
This one needs planning rather than a quick substitute, because Backblaze is not a folder you sync. It is an unlimited backup of your whole computer, and the copy in the cloud is tied to the Windows machine that made it. Once that machine is gone, you have a limited window to download your data before the backup expires, so restore anything you might want before you wipe the disk, not after.
Backblaze also sells B2, which is separate cloud storage rather than the backup app, and B2 does work from Linux. That is a different product with different pricing, charged by the gigabyte instead of a flat fee, and setting it up is more of a project than most home users want.
The simpler path for most people is a backup app on Linux that copies to an external hard drive, plus cloud storage for the files that really matter. Déjà Dup is already installed on Ubuntu and does the first job with two clicks.
Built into Ubuntu. Set it at an external drive, pick a schedule, and forget about it. Can also back up to some cloud services.
Your files: Cannot read Backblaze backups. Restore your files from Backblaze first, then let this app protect them going forward.
Similar job with clearer wording about what is protected and a quicker restore screen. Works to an external drive or a network folder.
Your files: Cannot read Backblaze backups. Starts a fresh backup of your files.
Cloud storage rather than whole machine backup. Useful for the documents and photos you want available everywhere.
Your files: No Backblaze import. Files are uploaded fresh.
One stubborn program doesn't have to decide the whole question. You can keep Windows on the same PC and restart into it only when you need Backblaze. Everything else you do can move.
