I was talking about our backup strategy to my wife tonight (2 sets of full backups, nightly incremental backups onto CDRW: again, 2 CDs that we cycle between), and we started discussing what seems to be a huge hole in this common strategy.
Namely, if you damage or lose any file you've worked on since the last full backup, and don't notice within two days, then the work will be lost - wiped out by the nightly incrementals! This likelihood obviously increases as the length of time between full backups increases. E.g. for us, we only fill an incremental CD a few times a year, so we only do a few full backups in a year. What's the accepted practice for solving this problem? I thought of keeping a 3rd CDRW for the incrementals, that only gets pulled out and used say on the 1st of each month. At least then you have a month to realise you have some damaged or lost files. ANd you could I suppose extend this to have 2-monthly, 4-monthly media you used, and have some complex scheme for pushing and popping them, so that for N media, you could be safe for 2^N months. But that seems complex. luke -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
