Limit the size and retention of legacy logs
Because legacy debug logs can grow very large, enable them only if unexplained problems exist. Delete the logs and the associated directories when they are no longer needed.
Limits the time that NetBackup retains NetBackup process logs (except media and device management logs). The default is 28 days.
Controls log file rotation for media and device management legacy logs. The default is 30 days. The vm.conf file is located in install_path\Volmgr\ or /usr/openv/volmgr/.
With legacy logging, NetBackup uses the configuration file (the Windows registry or the bp.conf file on UNIX) to set the maximum size of a log file. Use the bpsetconfig command to configure the following bp.conf parameters:
The MAX_LOGFILE_SIZE parameter indicates the maximum size of a log file. When the log file size in NetBackup matches the MAX_LOGFILE_SIZE setting, the next logs are stored in a new log file. The default is 500 MB.
The MAX_NUM_LOGFILES parameter indicates the maximum number of log files that can be created in NetBackup. When the number of log files matches the MAX_NUM_LOGFILES setting, the older log files are purged. The default is 0 (infinite).
