Agreed. RAID doesn't stop you from being stupid. But a backup e.g. on DVD doesn't stop you from leaving the DVDs lying in the sun, either. I'm not saying that RAID 1/5 is the end all, be all solution, but it always depends on how much effort (time, money and hardware wise) you're willing to spend. Mounting the music partition read-only and mounting it only rw when necessary (e.g. when adding new music) already stops you from doing most of the not-so-clever things, including the above mentione rm -rf ;) > Actually, the best (and cheapest, easiest) option in the case of most > music stores (which tend to rarely change) is to use a second > (non-RAID) disk and nightly synchronisations using something like rsync > (local or over the network).

Sure, if one's willing to have not just one, but two or even more PCs running, this is even better. Just make sure your rsync doesn't do a full sync and also delete files ;) You could as well keep another copy of the data on a independent disc (maybe even attached to the same computer), only mouted when needed for backup, and keep a copy of the data there. Needless to say that you could as well use RAID there. RAID is not the answer to all backup needs, but it keeps you fairly safe from hardware failures. And if I'd have to choose from a standalone single-disk NAS and a standalone PC with mirrored disks, I'd always pick the latter. -- Jochen ------------------------------------------------------------------------ Jochen's Profile: http://forums.slimdevices.com/member.php?userid=5682 View this thread: http://forums.slimdevices.com/showthread.php?t=24634 _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/discuss
