emulator Posted June 4, 2009 Report Share Posted June 4, 2009 I have noticed that when two scripts that need the same backup tape drive overlap (for whatever reason), Retrospect simply "stops" trying to process BOTH scripts. Even when trying to force one of the scripts to take a tape from the needed drive, the Retrospect's option to "proceed" is greyed out. I had to cancel both scripts and then start them over. I would like to see better handling of this type of conflict. Quote Link to comment Share on other sites More sharing options...
blm14 Posted June 5, 2009 Report Share Posted June 5, 2009 I have multiple scripts going to tape and it works fine. I only use proactive backup though... Quote Link to comment Share on other sites More sharing options...
Lennart_T Posted June 17, 2009 Report Share Posted June 17, 2009 You may need to elaborate a bit. When that happens here, the second scripts simply waits until the first script is finished using the tape drive. Quote Link to comment Share on other sites More sharing options...
emulator Posted June 24, 2009 Author Report Share Posted June 24, 2009 They may be what is supposed to happen, but we have seen on several occasions the following: 1. Script "A" calls for a tape drive, which is going to spam multiple tapes. 2. As script "A" is using the tape drive, it fills up a tape and calls for another, blank tape (we have an autoloader). 3. During the time that script "A" is switching tapes, a second script, script "B", calls for the same drive. 4. Both scripts are now deadlocked. Neither one will budge until one of them is forcibly quit. I know that this is a very obscure scenario, but it does happen from time to time.

blm14 Posted June 25, 2009 Report Share Posted June 25, 2009 aha! I only have one tape drive attached - that may be why I am never experiencing this problem... Quote Link to comment Share on other sites More sharing options...
Lennart_T Posted July 8, 2009 Report Share Posted July 8, 2009 3. During the time that script "A" is switching tapes, a second script, script "B", calls for the same drive. I see. (I think.) Are scripts A and B using the same backup set? (They do here and we have no such problem with our loader.) Quote Link to comment Share on other sites More sharing options...
emulator Posted July 8, 2009 Author Report Share Posted July 8, 2009 Are scripts A and B using the same backup set? (They do here and we have no such problem with our loader.) No...they are using different backup sets. HOWEVER... I think that I may have found out why this happens. Over the weekend, we had another one of these "fighting over the same drive" issues, and upon further inspection, one of the scripts was not bound to a specific drive. We normally bind tape sets to specific drives, but I apparently forgot about this one. I'll see if the problem crops up again in the future.
