Safety copies not being deleted on full backup
We recently upgraded from EV9 to EV10, and I just started noticing that our safety copies are not being deleted on full backup. I have only had 2 or 3 full backups since the upgrade so I am not sure if its been broken since the upgrade, or broke after. I attempted a manual full backup yesterday to see if there was an issue with the backup and it appeared to complete without issue, however I noticed this morning that EV admin console was reporting 'vault store in backup mode' so there may be an issue with the process automatically clearing backup mode.
Im not sure where to start troubleshooting with this, I dont have any errors jumping out at me in the event log, and im not sure which EV logs to look through.
I checked C:\Program Files (x86)\Enterprise Vault\Reports\Exchange Mailbox Archiving and I do not have any logs more current than 12/5/12.
The only thing I can think of that may be affecting this is I have started the process of converting indexes from 32bit to 64bit, but I have only done less than 5% of the mailboxes.
I backup the EV server using NetBackup 7.5.3 using the 'enterprise-vault' policy.
I am running EV version 10.0.1.1171
I appreciate any input or thoughts you guys have!
