We are using Microsoft Exchange 2000 on a active/active Windows 2000 cluster. We are unable to get consistent backups. The backups fail often whether we use Windows 2000 backup or Veritas Netbackup Datacenter 3.4.1. The backup errors on Netbackup are “FS_COMM_FAILURE”. We have been working with Vertias tech support & they told us that his is a known issue with Exchange 2000 & this happens due to Memory Fragmentation with the Store.exe process. Veritas has a case open with Microsoft about this &the case ID is SRX010823602493. We have to reboot the Exchange server every 2-3 days to clear out the fragmentation & get good backups. Has anybody faced this problems? How do we get good backups for Exchange 2000 & reduce the rebooting? Please help.
