Brian from Backblaze here. We support Linux now with our command line tool found here: https://www.backblaze.com/b2/docs/quick_command_line.html https://www.backblaze.com/b2/docs/quick_command_line.html There is no GUI, but the command line tool can "sync" your files with an arbitrary roll back time (the Mac/Windows client are hard coded to 30 days). For good or bad, syncing to B2 charges "per GByte". If you have less than 1 TByte this will be cheaper than the $5/month for the Mac or Windows client. But if you have more than 1 TByte on Linux, it will cost you about $5/TByte/Month to back it up.
