recently i am facing a strange thing, there are several storage group on my Exchange 2007 CCR environment, there is one storage in each storage, i am backup it via Commvault.
recently i found one of storage could not do full backup, it always stack there on Commvault, and there is not any useful info from Commvault thats why it not success.
mailbox on this storage works well, and i did try enable circular log and then disable it, reset exchange information store service, dismount and mount the storage, all doesn't help, also i did check cluster function and replicate health, all is fine, so only this storage has backup issue, others is fine.
so do you know whats wrong with it? how and what else i need to check this storage group and storage? i have export Commvault backup log but i did not find out anything to help, let me know if you need read it first
