I currently have for Exchange 2010 servers, two hub/cas and two mailbox servers in a DAG. I ran a full backup on of mailbox server #1 including OS/system state/exchange data) and on mailbox #2 of os/system state only but NOT Exchange data using Unitrends backup. According to the backup console, the backup completed successfully and I am seeing events saying the following:
1. ESE event 2001 Information Store (3464) database_name_here: Shadow copy instance 96 freeze started.
2. ESE event 2003 Information Store (3464) Shadow copy instance 96 freeze ended.
3. ESE event 225 Information Store (3464) database_name_here: No log files can be truncated.
4. MsExchangeIS event 9827: Exchange VSS Writer (instance f8b0064b-7a70-44b7-94e2-a5c1b0adfd45:96) has successfully completed the full or incremental backup of replicated database database_name_here. The log files will be truncated after they have been replayed.
3 and 4 seem to conflict. When I do this, I am not seeing any truncation of the logs on either mailbox server. When I ran a get-mailboxdatabasecopystatus on the affected database, it is listed as "mounted" on mailbox server #1 and "healthy" on mailbox server #2. The copy queue length and replay queue length are both listed as 0. The content index state is listed as healthy on both servers for that database.
I tried dismounting and remounting the databases and that had no effect. Circular logging is currently not enabled and I do not wish to enable it.
Thanks in advance for your help.
