Good move, but you'll get faster backups and less SSD wear, if you're
backing up to SD cards or SSDs, if you do it with either rsync or
rsnapshot.

I use both: rsnapshot for my overnight backup (I used to use compressed
tar beckups and this brought the backup time down from 3 hours to 8
minutes AND the backup can be accessed without needing to uncompress/untar
anything) and rsync for my weekly backup to the set of disks kept offline
in a firesafe.

No need to unzip if you use rsnapshot or rsync, so recovery is faster:
just find the file(s) by looking through the directory structure and copy
them back.
