I glanced at your log and it's full of ata2.00 disk errors - filter on 
that in journalctl or dmesg and you'll see them. If you're lucky it's a 
cable or connection, otherwise your disk is dying.

You had a reply advising using a "proper" filesystem with snapshotting 
which is excellent advice. They suggested BTRFS however which is 
terrible advice - ignore that and use ZFS instead.

Cheers
