I recently upgraded from version 9 to 11.5. I've noticed in d:\program files\ca\brightstor backup agent for exchange. I have an EXCESSIVE amount of files. The pattern is at#number.number. such as, AT#77569.6160; AT#7757.3604. The date and time stamps appear to coincide with the brick level backup start and stop times when I used version 9. There are so many of these files in this folder that it causes my tcp/ip connection to revert to named pipes during backup. Short-term, I have removed this folder from my backup. What are these files and can they be safely deleted? I tried to open an issue with CA today but they are having problems on their web site and since this is not a show stopper, I did not want to hang on the phone. Can anyone offer any insight on this one? thank you
