Dear All,
I´ve found this message below in Veritas-BU list.
I´m particulary interested in knowing a little bit more about the
environment and right configuration for using NBU Exchange Agent.
I have a very similar configuration: 2 machines with about 2200 mailboxes and
60 GB of total size each.
They together are spending 108 hours to complete the whole backup with Veritas
NBU Exchange Agent,
W2K NetBackup 4.5 M5, using 4 x 9840B.
Are you using, in your policies rules, the information store of the mailbox?
Thank you in advance for any information you can give me.
Regards,
Ana Luísa
