Each log file is rotated once the log file reaches a size greater than 10KB. When the size limit
is reached, the old log is renamed to a new name containing the rotation number (such as
debug.log.1) and a new (blank) log begins with the default name. All rotated log files are
compressed (using gzip) after the second rotation except for the first log file (most recent). If
the file is compressed, .gz is appended to the log file name. This file is renewed each day at 4
a.m. Up to 30 files are saved for each type of log.

Event log
The event log file is an especially useful log that is generated by VTS. It records information
about system events, such as the creation and deletion of virtual tapes, failures of processes
and services, and the status of jobs and policies. The messages include information about the
time and date of the event as well as the name of the user who initiated the event. Use the
messages in this file to detect problems, track down the source of faults, and audit users. In
addition, information in the system event log can be retrieved by third-party applications,
such as Prognosis or Insight Manager, for notification purposes.
