@CheetahFluff You might like OpenZFS or BTRFS. You can really only do this kind of thing & have 100% of your data safe if a disk fails by having a RAID with parity or a mirror setup. Both BTRFS & OpenZFS make it very easy though. After that it should work on its own without you needing to touch it, except to use a command to make it accept a replacement disk when needed. Remember that a mirror or parity disk isn't equivalent to a backup though. It just makes it less likely that you'll need to restore a backup, so you still need a separate backup. Both BTRFS & OpenZFS have a "send" function that you can use to send a complete filesystem backup to a remote server or another pool on the same device, & it's good for backups.
