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. Easy to set up. Easy to use, only takes a couple of minutes to ‘re-set’ your system back, if you break it. If you want just to backup files, documents etc then Cron. I use both. They are standard Linux programs and easy to use
