Backup Central

I'm running backups using TDP for MAIL - Exchange 5.5.1
Running fulls daily. And the trans logs are not being deleted.

No errors. No failures. The documentations indicates that Exchange is
supposed to perform this maintenance upon completion of a full backup.

A premiere call was placed with Microsoft. They state that the backup
software is supposed to perform the deletion.

Any ideas ?

Backup software only deletes the logs if you tell it to. Is your TDP configuration setup with the "with truncate" option? (From memory)

I think MS left you with a false impression of the processing. From
what I understand, it is always the Exchange server which performs the
deletion, incited to do so by virtue of a full or incremental online
backup of all the databases in a storage group is performed (circular
logging disabled). See http://support.microsoft.com/kb/240145 .

See also the FAQ appendix in the TDP manual, question
"How do the Exchange Server transaction logs get deleted?"
for further insight.

The Exchange log and/or Windows Event Log may have further info on
what transpired.

You are correct Rich,
What TDP does is only tell Exchange that the backup is done successfully and Exchange can clean the logs when it need it.
TSM for Mail has nothing to do with the logs anymore as it was before.

Thanks
Christian

As some of the listers have already mentioned...

Data Protection for Exchange tells the Exchange Server that the
full (or incremental) backup was successful and that it is now safe
to truncate the logs. The actual log files get physically deleted by the
Exchange Server, not Data Protection for Exchange. There are a few things
that can sometimes "delay" this truncation. One such thing is
LCR or CCR replication on Exchange Server 2007.

If you are worried that Data Protection for Exchange is not doing
something correctly... you can certainly open a call with IBM support.
They will most likely have you turn on tracing... and look for this in the
trace:

=====================================================================
backupsg.cpp (1764): Enter CBackupSg::truncateExchangeLogs()
backupsg.cpp (1775): Calling HRESEBACKUPTRUNCATELOGS( 0x1d0cfa00
)...
e2kapidl.cpp (1102): Enter CE2kApiDL::hrEseBackupTruncateLogs
baseapi.cpp ( 183): Enter DBaseApi::StartApiCall()
baseapi.cpp ( 188): Exit DBaseApi::StartApiCall()
baseapi.cpp ( 242): Enter DBaseApi::EndApiCall()( Exchange )
baseapi.cpp ( 263): Exit DBaseApi::EndApiCall(), elapsed seconds
0, total time 0 for Exchange Apis
e2kapidl.cpp (1110): Exit CE2kApiDL::hrEseBackupTruncateLogs
backupsg.cpp (1790): HRESEBACKUPTRUNCATELOGS() was successful.
=====================================================================

The HrESEBackupTruncateLogs() function notifies ESE (Exchange database
engine)
that the database (full) and logs (full, incr) have been backed up
successfully,
so it can delete the logs when it is ready.

Thanks,

Del
