Short-term: document that recovery procedure.

Medium-term: It's sometimes possible (not easy, possible) to replace the
EEPROM battery, or to hook up another battery to the right pins on the
EEPROM chip.

Medium-term: disks and fans die.  If it has RAID or mirrored disks, at
least the disk failures aren't fatal.

For the longer term: make a complete disk copy, as in
dd if=Sun-disk(s) of=whatever, and then look into virtual machines,
qemu, and the like.

Just a suggestion,
