I have a back up on an SD Card waiting for the day the SD Card fails. Slot it in and reboot
I recently "upgraded" one of my raspberrys SD cards to an industrial grade one. Seems to me like those are a lot slower but for that particular use case it doesnt matter to me. What matters is that the card doesn't die. It runs noticeably cooler when lots of data is being written to it so I feel like I must be onto something there.
Routine backups of the VM's and raid disk for the hypervisor running them. If the box hosting the backups went screwy there's a problem but with something like 20TB of space used copies off-box are a bit cumbersome. To that end I just manually copy the irreplaceable stuff to a separate external storage and wish the movies and stuff good luck.
It ends up with a situation though where I'd have to lose both the disks on the hypervisor and if that happened several disks on the NAS (12 disks in a ZFS pool with each vdev being a mirror pair) or for the whole pool to get screwed up to lose the VMs fully. Depending on the day I might lose up to a week of VM state though since they only do a full copy once a week.

I use duplicati for docker containers. You just host it in docker and attach all the persistent volumes from the other containers to it, then you can set up backup jobs for each.
