Thanks to all, Wanda, Richards, Andrew and Mitch! This list is the best! The guy at IBM support was sympathetic but of course, no support due to long time out of date software. (It is not his fault, and he was really nice about it)
Well I didn't use mirroring - but will soon ... just after this is restored :) - and that would have really have made this a 'non-problem'. We do daily full backups of the database, but do not do the roll forward of recovery logs. Thanks to all for all the support. ... Now for our offsite tapes to arrive. ... Jack
