We have Exchange 2007 server setup. CAS,HT roles are installed on one server & mailbox server role is installed using CCR(Active & Passive Node).
Mailbox server-- Windows 2008 Enterprise x64 bit & Exchange 2007 SP1 Enterprise edition SAN storage is attached to mailbox server.
CAS&HT -- OS -Win2008 STANDARD x64 bit & Exchange 2007 SP1 STANDARD edition. These roles installed on two server using NLB
What should be the backup strategy for Mailbox server role? Should I schedule backup job on passive node or active node? If we schedule backup on passive node, the transaction log will get purge automatically on active node or they will again get replicated to passive node from active node&?? In CCR we should use daily full backup or not??
When I try using windows backup, it will backup entire volume. So does this backup will purge transactional logs also??
For HT & CAS what data need to be backed up??
Any help on this will be appreciated..Thanks in advance..
