The number of backup system log files kept in the log directory.
3
An integer greater than or equal to 1.
When the system log wraps, Mirror Replication Agent copies the current log file to a backup file, with a generated number appended to the file’s name.
For example, if the system log file is named my_mra.log, the first backup file created when the system log wraps would be named my_mra1.log. The second backup file created would be named my_mra2.log, and so on.
When the number of backup files exceeds the value of the log_backup_files parameter, the oldest backup file (that is, the one with the lowest generated number) is deleted from the log directory before the next backup file is created.
