I am currently using EndeavourOS for my laptop. Is there a backup solution that is easy to use, and can be run from the EndeavourOS install media without internet? (RSync is included, but no other backup tools are included, to my knowledge.) I don’t want to use another ISO due to space constraints on my USB.
Timeshift for system files, Backintime for user data.
Neither of those are backup tools. They’re snapshotting tools.
Snapshots are incremental backups.
