As an atheist, I ask for prayers that the backup's good.

E: Your solidarity has worked. The backup is good and not too old. Note for myself and you - install your OS on a snapshotting filesystem so that live backups are possible.

This is your OS disk? How would having a snapshotting OS like btrfs have helped in your situation?

    Root on Btrfs/ZFS would have ensured I have a root backup from an hour ago. Ext4 (without LVM) means I can only make a backup every now and then when I turn off the machine, boot into alt OS and take an offline copy.

    Would've been transferred to the big redundant storage. Whe using ZFS in particular, local snapshots are essentially instant, then ZFS transfers only the missing snapshot delta to the other ZFS storage, delta tends to be very small and therefore fast. Put those thigs together and hourly live full system backups become very practical. I already have this setup for my laptop. Restoring a complete system from backup becomes - ZFS sync from the backup to the new drive, restore the EFI partition, boot from it.
