Hi All, I have a simple question. Can backup using two different tools run together. It can run for sure, I know. However question is will there be any conflict if we have to restore? Are they independent of each? Example: onarchive and ontape. Taking L0 and L1 for both these. With Best regards, Jo

If you take whole archives (L0, L1, L2 _and_ logs) with one tool, and then use another to do the same, that's absolutely fine. You have either archive to go back to. But intermixing - that doesn't bear thinking. don't do it. ever. period. As a side note, using onbar and switching storage manage mid archive, so that you have certain logs and dbspaces on one storage manager, and others on the other is an equally bad idea. I do remember spending several hours writing a small xbsa client and moving logs from one storage manager to another when somebody did just that and then found himself in the position of having to do a cold restore a couple of hours later... -- Ciao, Marco ______________________________________________________________________________ Marco Greco /UK /IBM Standard disclaimers apply!

The system keeps track of all archives in reserved pages and/or the systutils database. Please be very careful about mixing backup methods and/or storage managers. It doesn't work. If you ever want to restore choose one method and stick with it. Restore is difficult enough without added complexities.
