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.
