Just make complete backups. Instead of putting your second hard disk in a mirror-RAID, put it in an eSATA or USB chassis or in some NAS device. RAID-1 does not replace backups. Its primary purpose isn't even data safety but high system availabilty - and unless you really need this, it is rather pointless. As you (unlike many others) recognized, you are the biggest danger yourself and the only way to protect against this, is regular backups. Either incremental/differential backups or - in my opinion ans experience much preferable at home: simple backups in combination with some snapshotting mechanism (LVM, btrfs, ZFS, ...). (You can use snapshots at your backup source to get consistent data, but also at the target to keep old versions.) Simply encrypt your backup disk using its own LUKS header and don't even bother with special header backups.
