From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Clonezilla has its place, but not as a main backup and restoration tool. I personally don't see it as a backup tool, especially that it operates at partition level for such. What you want is you base install system and file level backups for your data (/home/) etc. For the file level backups, use something like restic. Backup what you need to go from a fresh install to a system with your data back on it. Packages can be reinstalled.
Restic is my primary backup for all my devices. If I need something more than fresh iso -> my data system, I use packer.
I noticed for file level backups you mentioned something other than rsync. Any particular reason why you landed on restic instead?
Because that serve different purposes. rsync is for moving data around, synchronization of such. It has no concept of point in time restoration, or snapshots (etc) that really define a backup solution. I use restic because its the proper tool for the job.
Do you mean like not just having another copy of a file, but being able to restore a specific version of a file?
There's a lot more going on with restic aside from just that, but yes. So with an rsync of your home dir (for example), it's reliant on the FS to do compression and deduplication (ZFS,btrs), and/or it will still take up a lot of wasted space. Say you got ransom-wared. It's okay you have that rsync backup, but oh crap it got ransom-wared to. No more backups to try? Restic gives you snapshots for whatever increment you set and just handles it simply. You can then restore one file from any of the snaphots (history) or every single file. Restoreing 250kb vs 400TB is quite a difference. The benefits of this, are huge even beyond the fire and forget capability.
I mean, rsync handling everything via mirroring and pushed to a ZFS FS, would be sort of the same thing.
