NAME

backup_dbverify - Checks the integrity of the Backup Database

SYNOPSIS

backup dbverify [-detail] [-localauth] [-cell <cell name>] [-config <configuration file>] [-help]

DESCRIPTION

The backup dbverify command checks the integrity of the Backup Database. The command's output indicates whether the Backup Database is damaged (data is corrupted) or not. If the Backup Database is undamaged, it is safe to continue using it. If it is corrupted, discontinue any backup operations until it is repaired.

CAUTIONS

While this command runs, no other backup operation can access the Backup Database; the other commands do not run until this command completes. Avoid issuing this command when other backup operations are likely to run. The backup savedb command repairs some types of corruption.

OPTIONS

-detail

Reports the number of orphaned blocks found, any inconsistencies, and the name of the server machine running the Backup Server that is checking its copy of the database.

-localauth

Constructs a server ticket using a key from the local /etc/yfs/server/KeyFileExt file. The backup command interpreter presents it to the Backup Server, Volume Server and VL Server during mutual authentication. Do not combine this flag with the -cell argument. For more details, see backup(8).

-cell <cell name>

Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see backup(8).

-config <configuration file>

Sets the location of the configuration file to be used. The default file is /etc/yfs/yfs-client.conf.

-help

Prints the online help for this command. All other valid options are ignored.

OUTPUT

The command displays one of the following two messages:

Database OK

The database is undamaged and can be used.

Database not OK

The database is damaged. You can use the backup savedb command to repair many kinds of corruption as it creates a backup copy. For more detailed instructions, see the OpenAFS Administration Guide chapter about performing backup operations.

The -detail flag provides additional information:

EXAMPLES

The following command confirms that the Backup Database is undamaged:

   % backup dbverify
   Database OK

The following command confirms that the Backup Database is undamaged and that it has no orphan blocks or invalid Tape Coordinator entries. The Backup Server running on the machine db1.example.com checked its copy of the Database.

   % backup dbverify -detail
   Database OK
   Orphan blocks 0
   Database checker was db1.example.com

PRIVILEGE REQUIRED

The issuer must be listed in the /etc/yfs/server/UserListExt file on every machine where the Backup Server is running, or must be logged onto a server with an account capable of reading the /etc/yfs/server/KeyFileExt file if the -localauth flag is included. =head1 SEE ALSO
