Retrospect does some sort of script verification and notification at quitting time, and this can cause problems with quitting Retrospect and a UPS. These Retrospect notifications require user input, and if no one is at the machine to answer this dialog box, the computer never shuts down and a dirty file system occurs when power is cut off.
The solution is to uncheck the "Check Validity of Next Script" option in Retrospect. To get to this option, click on the Configure icon in the Retrospect Directory, click on the "Options" button, then click on "Quit Action" in the Program Options window. There you should see "Check Validity of Next Script." Retrospect will now quit without stopping for user input.
Another option in "Quit Action" is "Rewind Tapes." This will rewind any accessed tape to the beginnings. The purpose of this is to speed future access to Retrospect. This option should also be off for machines on a UPS. The UPS may not be able to keep the computer up long enough to finish rewinding the tape.
Note: These tips can also be applied to AWS60/80.
