E8602 but only in Differencial backup

[peeky1323]

Hi,

Server = Server 2003 SP1
Arcserve = 11.5 and latest patches
Exchange = 2003 in a cluster with the Exchange agent

I have a Multiplexing GFS backup job with a Full backup on Monday and differencial Tue-Fri. I have selected a full backup on our Exchange server. The Exchange agent is installed but only for Database level (not brick). The full bacup runs fine on Monday, and starting a month ago the differencial backups are failing to backup the exchange info store with the following error:

E8602 Failed to read from database (DBNAME =First Storage Group, EC=Invalid user ID or password

However this is the same job with teh same credentials as the full backup on Monday whihc completed fine.

Things I have tried:

1) Seperate backup of just Exchange in a new job (both Multiplexing and not) Noth of these work fine

2) In the GFS job I have set the Exchagne agent options to always do a Full. This made no difference

3) Reinstalling and configuring the Exchange agent

I had this problem when I was using 11.1 and upgraded to 11.5 last week and the problem is still there.

Any ideas aprreciated.

Thanks,

Matt

Enable debug for the Exchange DB agent. Instructions are in the faq section of the ARCserve forum.

Check if your GFS pool name has blanks or special caracters.
