Hey there, folks! Currently playing around with a laptop that’s got three SSDs. Running Arch but that isn’t quite related. I have everything configured on one SSD, the other two are totally fresh. What do I need to do to setup one of those fresh SSDs for Timeshift backups? Please walk me through it from the very start- I think I understand some parts but I’m not too certain.
I can format the drives using mkfs.btrfs without any issues, but I’m confused about how I can add subvolumes and configure their root permissions properly to allow Timeshift snapshots.
EDIT: I see now that I misunderstood what Timeshift does. New question- which tool can I use to make a backup of my entire filesystem onto another drive such that it can be restored?
That makes more sense- kinda like nondestructive editing when working with audio/video. The snapshot is more or less a list of instructions to revert a system back to a previous state, not an actual copy of everything.
