If going with an external backup and pars... I'd also add md5sums to the list.
I've had great success using external drives drives connected to a low power
device like the Raspberry Pi.
The full data system:
CPU 0 - Original is on host drive.
Pi 0 - Backup is RAID 1 [with two separate drives]
Pi 1 - Repair data is on separate backup drive along with md5sum lists.
All connected via network, rsync between machines. Cron scripts run nightly to
retrieve, verify -- md5sum -c first, repair data.
Additional cost is:
$70 for 2xRPi
$250 for 3x1GB drives

Whatever for? There are better checksums and md5 doesn't provide error
correction? Even the MD5 man page advises using sha checksums instead.
