bdb.db0

BDB.DB0(5)							AFS File Reference							BDB.DB0(5)

NAME
       bdb.DB0, bdb.DBSYS1 - Contain the Backup Database and associated log

DESCRIPTION
       The bdb.DB0 file contains the Backup Database, which records configuration information used by the AFS Backup System along with cross-
       indexed records of the tapes created and volumes dumped using the Backup System commands.

       The bdb.DBSYS1 file is a log file in which the Backup Server (buserver process) logs each database operation before performing it. When an
       operation is interrupted, the Backup Server replays the log to complete the operation.

       Both files are in binary format and reside in the /var/lib/openafs/db directory on each database server machine that runs the Backup
       Server.	When the Backup Server starts or restarts on a given machine, it establishes a connection with its peers and verifies that its
       copy of the bdb.DB0 file matches the copy on the other database server machines. If not, the Backup Servers use AFS's distributed database
       technology, Ubik, to distribute to all of the machines the copy of the database with the highest version number.

       Use the commands in the backup suite to administer the Backup Database. It is advisable to create a backup copy of the bdb.DB0 file on tape
       on a regular basis, using the UNIX tar command or another local disk backup utility.
