I'm a newbie admin for an Exchange 2003 server running on Windows Server 2003 R2 Standard, all storage on the server is local, no DAS, SAN or NAS. The server is being backed up to magnetic tape using Symantec Backup Exec 12.5 running on Windows Server 2008 Standard x64.
There are daily, weekly and monthly backup jobs for the server. All three jobs backup all items under the server name in the selection list, all the disk partitions, shadow copy components, system state, utility partition and Microsoft information store. Under the Microsoft Exchange section in the job properties, the Full backup method is selected. Use Backup Exec Granular Recovery Technology is selected. Perform consistency check is selected and continue with backup if consistency check fails is selected.
I also noticed that transaction logs under \mdbdata don't get flushed, although circular logging is not enabled.
Being a total Exchange noob, i don't really know much about the information store, storage group, transaction logs....etc. or their overlaps and interdependencies.
However i feel there's some waste, inefficiency or double backups of the same data happening here.
Can you please give me some advice on how to optimize the backup process ?
