No need for elaborate guides. :-) Any data that isn't securely backed up, including offsite, isn't really important to you. However, having other measures in place can be worthwhile as well, for convenience if nothing else. In particular, a UPS is usually a good idea, and monitoring it so the system does a clean shutdown before running out of power can make it even more so (not in all situations, but in many). Integrity checks on files will catch damage to files; ZFS does this automatically, but mtree(8) can do various types of checksums to serve the purpose as well. -- Lowell Gilbert, embedded/networking software engineer, Boston area http://be-well.ilk.org/~lowell/
