@billyjoebowers I have heard good things about BorgBackup.
In the end, you could just setup a shell script doing rsync to an external drive.
@truls46 @billyjoebowers Redundancy is not a backup. This will happily rsync a wiped or cryptolockered system over top of your "backup".
rsync can be told to only add, but not remove files if I'm not mistaken, so it would not wipe anything.
But what's your recommendation for a stable and easy to use backup using Linux?
@truls46 It would wipe if they'd been replaced with maliciously encrypted versions of their prior contents, or if you'd accidentally modified them in lossy ways. Even something as innocent as browser profile getting corrupted on crash & losing everything on next sync.
@truls46 As for my recommendation, I've heard good things about Borg. I use bakelite which I made and which has stronger cryptographic properties, but it doesn't have polished UI or setup workflow - I need to get to that someday.
@dalias Ah, that's what you mean. Yes, absolutely. How can you protect your (automatic) backup strategy against that?
@truls46 By having the backup medium be enforced append-only from backup clients, and keeping enough past (preferably incremental so you don't need astronomical amounts of storage) images that you're sure to have one before unnoticed catastrophic loss.
