Hi Everyone,

I'm just curious and confused, how come after full backup of my Exchange Server 2007 SP1 with CCR using HP Data Protector (A06.11) one of my Storage Group transaction log partition still not cleared ?

I wonder if there is any log file that can be safely deleted from Windows Explorer.

While the other partitions can be as low as 0.1 GB after the full backup, but only this one particular stays about 11 GB.

Any kind of help and pointer to troubleshooting this issue would be greatly appreciated.

The inactive database is updated by the active node shipping log files
to the inactive node. On the inactive node the transactions in the log
files are applied to the database. When those transactions are
successfully committed to the inactive database the inactive node
conveys that information to the active node. Once the active node
knows the log files have been committed to both copies of the database
it notes that fact and will allow those log files to be removed.

Ah, so how do i know which log files are safe to be deleted from windows explorer ?

I read somewhere about  getting the database shutdown state but somehow I forgot about it.
