What I do is use rlbackup via cron to periodically copy stuff I care
about from one disk to another.

rlbackup is just a thin layer of scripts around rsync.

Compared to RAID, I lose high availability uptime preservation or the
ability to recover files created since the last cron run, but I gain
the ability to recover accidentally deleted files, or revert files to
previous previous versions after certain ill advised system
administration events.  This has saved me a number of times where a
RAID wouldn't have been any help at all.
