We are running Symantec Backup Exec 10d on two servers in SiteA and SiteB but have a problem with the time taken to backup Exchange Server on the server in SiteB.
A full system backup on Server in SiteB has a total 66GB of which 29GB is Exchange Server and 37GB is system files and other data. The 37GB backs up in just over 2 hours but the 29GB of Exchange Server takes a further 17 hours. The backup in SiteA uses the same tape drive and same software and backs up a total of 71GB in just over 5 hours, although only 8GB of this Exchange Server data.
Does anybody have any idea what might be causing this problem?
