Can a long backup also be caused by antivirus programs running on Exchange Server?
Dalibor C. ****************************************** It is possible that antivirus software could slowdown a backup, if the antivirus software is accessing the information store(s) at the same time as the backup — especially if the backup software and the antivirus software are utilizing the same MAPI (Messaging Application Programming Interface). Of course the best way to find out is to stop antivirus software services when backing up the mailboxes.
