This is the initial conversion of the AFS Adminstrators Reference into POD for use as man pages. The man pages are now generated via pod2man from regen.sh so that only those working from CVS have to have pod2man available. The Makefile only installs. The pages have also been sorted out into pod1, pod5, and pod8 directories, making conversion to the right section of man page easier without maintaining a separate list and allowing for names to be duplicated between pod5 and pod1 or pod8 (which will likely be needed in a few cases). This reconversion is done with a new script based on work by Chas Williams. In some cases, the output is worse than the previous POD pages, but this is a more comprehensive conversion. This is only the first step, and this initial conversion has various problems. In addition, the file man pages that didn't have simple names have not been converted in this pass and will be added later. Some of the man pages have syntax problems and all of them have formatting errors. The next editing pass, coming shortly, will clean up most of the remaining mess.

|
|
bdb.DB0 and bdb.DBSYS1 - Contain the Backup Database and associated log
|
|
|
|
=head1 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 (B<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 /usr/afs/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
|
|
B<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
|
|
B<bdb.DB0> file on tape on a regular basis, using the UNIX
|
|
B<tar> command or another local disk backup utility.
