Veritas NetBackup™ Logging Reference Guide

About limiting the size and the retention of legacy logs

Certain NetBackup processes write legacy debug 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.

See About log retention in NetBackup.

To limit the time for which NetBackup retains logs, specify the number of days in the Keep logs for days field. The default is 28 days. You can specify the number under Host Properties in the Logging dialog box.

See the NetBackup Administrator's Guide, Volume I for more information about logging properties.

To limit the amount of disk space that the logs consume, use robust logging. Robust logging involves file rotation, like that which is used in unified logging. Robust logging does not apply to media and device management logging.

See About rolling over unified log files.

Specify the maximum size for a log file and the maximum number of log files to keep in a logging directory. When a log file grows to its maximum size, it closes and a new file opens. If the number of log files exceeds the number that is allowed for the directory, the oldest file is deleted.

For the logs that are created by the other NetBackup processes (except media and device management logs), use the Keep logs for days property. The Keep logs for days property may override the robust file logging settings. If Keep logs for days is set to 10 days and robust file logging settings allow more than 10 days, the logs are deleted on day 11.

For media and device management legacy logs, use the DAYS_TO_KEEP_LOGS setting in the vm.conf file to control log file rotation. The default is 30 days. The vm.conf file is located in the following directory:

To retain logs for 3 days, enter the following in the vm.conf file:

DAYS_TO_KEEP_LOGS = 3
