ZBackup VS rsnapshotThat

I've been doing semi-regular backups with mintbackup, but it's gotten to the point where my backups are filling up the drive even when I gzip them individually. Because these backups contain a bunch of the same files over and over again, I looked for a way to de-duplicate the backups and I landed on zbackup. It looks like it does what I want and my tests are promising, but I wanted to know if there were any caveats or if there are any better solutions out there.

[I] app-backup/zbackup [1] Available versions: (~)1.4.4-r2 **9999 {tartool} Installed versions: 1.4.4-r2(09:57:06 02/07/21)(tartool) Homepage: https://github.com/zbackup/zbackup Description: A versatile deduplicating backup tool

I use zbackup which is quite similar in concept to Borg (doesn't offer mountable images tho) with cron jobs such as the bash script below which backs up all the root folders except for selected things like /dev

I use zbackup ("globally-deduplicating backup tool, based on the ideas found in rsync") from a cron job which saves more space than just using links (ie it can recognise moved files, renamed files, and files that are only partially edited).

Ok, being an RW disc its not read only but malware would have to do a lot of work to modify it!This process isn't perfect. I'd like my snapshots to be read only on the HDD and NAS but I haven't implemented it yet. It also is not automated. I change very little data so snaphots are made on an ad-hoc basis.https://github.com/rsnapshot/rsnapshotThat is also based on the same page I used and basically does the same thing. Bear in mind it has not been worked on for a bit and there are a couple of issues some people have in certain situations and configurations so YMMV.https://backintime.readthedocs.io/en/latest/index.htmlMay be what you need. Remember, you have to mount the share. UNC paths wont work. Also as stated in the documentation you need to enable links in smb.comf as Samba has hard and symbolic links disabled by default.I'm not using this to backup the entire system and OS. Just my data. I will re-install if I need to.
