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.
I use backintime and have for a number of years. It is incremental with unchanged files being hard-linked and makes it easy to restore files if needed.
