I'm ok to pay for it but:
1 - I need the client to use encryption and be open source
2 - It needs to run on linux
3 - It needs to backup files in arbitrary locations, including spanning several partitions (one NTFS, one ext3)
4 - It needs good filtering / curation capabilities
5 - Restore should have great granularity, and I should be able to browser the archive without having to unpack it all
6 - it needs to be easy to setup. I don't want to setup my own instance or mess with config files.
I've never found a tools that could do all that. One of those always fail, and sometimes the tool promise all of them, but doesn't even manage to backup. Some backup only partially, missing a files. Some backup, and don't restore. Some can only restore the all archive. Some don't encrypt. Some are close source, or only available on Mac and Linux. Some will store wrong files, and you can't them out of the backup.
It's crazy that in 2021, the state of backup sucks so much.
So have 2 backups on 2 different hard drives for all my files. One with "way back machine", the other one with a simple cp. Then I take essential files, and I put them on a usb drive.
My only remote backup are githup repo and emails.
Any suggestion?
