Hi to all I have an environment for my Exchange as:
· 2 servers with exchange 2010 · O.S Windows 2008R2 64B · TSM client version 7.1.1 · TSM TDP for exchange version 7.1.0 · TSM server version 7.1.1 I backup those exchange server with DAG configuration ( only one filesystem) with the configuration of proxy as: Target Node Agent Node --------------- --------------------------------------------- EXCHSRVAN_DB EXCHSRVA EXCHSRVBN_DB EXCHSRVB DAG_EXCHANGE EXCHSRVA EXCHSRVAN_DB EXCHSRVB EXCHSRVBN_DB All the databases’ are configure on each server as half active and passive and vice versa. I run every day 3 logs backups and one a week a full backup for each server with those commands: Logs: start /B tdpexcc backup * incr /MIN=60 /EXCLUDEDAGPASsive /SKIPINTEGRITYCHECK /tsmoptfile=dsm.opt /DAGNODE=DAG_EXCHANGE /logfile=excsch.log >> excincr.log Full: start /B tdpexcc backup * full /MIN=60 /EXCLUDEDAGPASsive /SKIPINTEGRITYCHECK /tsmoptfile=dsm.opt /DAGNODE=DAG_EXCHANGE /logfile=excsch.log >> excfull.log I understand via documentation that DP/Exchange does not actually truncate the logs, the Exchange Server does the actual truncation. When a DP/Exchange backup completes successfully, it will tell the Exchange Server that it has stored the backup and that it can truncate the logs. At that point, the Exchange Server decides on the appropriate time to truncate the logs. So if one or more of my DB log got full I need first to increase the space on each server and only after it to run a log or full backup of this specific DB to clean the logs? It’s a parameter /PREFERDAGPAS that I don’t quite understand the purpose and if I need it on the commands ? Any other suggestions will be appreciate too. Best Regards Robert Ouzen
