# Administration Reference

## BackupLog

Purpose

Traces Backup Server operations

Description

The BackupLog file records a trace of Backup Server (buserver process) operations on the local machine and describes any error conditions it encounters.

If the BackupLog file does not already exist in the /usr/afs/logs directory when the Backup Server starts, the server process creates it and writes initial start-up messages to it. If there is an existing file, the Backup Server renames it to BackupLog.old, overwriting the existing BackupLog.old file if it exists.

The file is in ASCII format. Administrators listed in the /usr/afs/etc/UserList file can use the bos getlog command to display its contents. Alternatively, log on to the machine and use a text editor or a file display command such as the UNIX cat command. By default, the mode bits on the BackupLog file grant the required r (read) permission to all users.

The Backup Server records operations only as it completes them, and so cannot recover from failures by reviewing the file. The log contents are useful for administrative evaluation of process failures and other problems.
