More seriously, on a personal level, I run Deja Dup on my Mint laptop to a USB disk that's LUKS-encrypted. Of course, that's not enough, so I have a script running on my home DHCP server - when a DHCP lease is granted, if the MAC matches my laptop's ethernet adapter, it runs rsync over SSH to my user folder (on a RAID1) on the server, doing a one-way sync. From there, I have an LTO3 tape drive that I got cheap on eBay, and I dump the folder to tape with tar weekly (cycling through the tapes, of course). Anything irreplaceable, I keep in Dropbox, mirrored to every machine I have access to. If I were to manually delete the folder by accident, I've got 7 days to restore it on the Free tier. And if Dropbox itself does a GitLab, chances are very high that I have one of my machines with a recent sync powered off, so booting that up without network will get me a reasonably up-to-date folder. It's a lot of moving parts, but everything is usually nicely in sync. I recently reinstalled my Mint laptop and restored from the Deja Dup backup, so I'm reasonably confident it would work in a DR scenario.
