BACKUP_LISTDUMPS(8)					       AFS Command Reference					       BACKUP_LISTDUMPS(8)

NAME
       backup_listdumps - Displays the dump hierarchy from the Backup Database

SYNOPSIS
       backup listdumps [-localauth] [-cell <cell name>] [-help]

       backup listd [-l] [-c <cell name>] [-h]

DESCRIPTION
       The backup listdumps command displays the dump hierarchy from the Backup Database.

OPTIONS
       -localauth
	   Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile 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).

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

OUTPUT
       The output displays the complete dump hierarchy and indicates the relationship between full and incremental dump levels. Full dump levels
       appear at the left margin. The hierarchy can include more than one full dump level; each one defines a subhierarchy of dump levels that can
       be used for dumping different volume sets.

       Incremental dump levels appear below and indented to the right of their parent dump levels, which can be either full or incremental. Since
       multiple incremental dump levels can share the same parent, an incremental dump level is not always directly below its parent; the amount
       of indentation indicates the parent/child relationship.

       If a dump level has an associated expiration date, it appears along with the level name. Absolute expiration dates appear in the format

	  <dump_level> expires at <day month date time year>

       and relative expiration dates in the format

	  <dump_level> expires in {<years>y | <months>m | <days>d}

       to indicate the number of years, months, days, or combination of the three after creation a dump expires when created at this level.

EXAMPLES
       The following example depicts six dump hierarchies. The expiration date for all incremental dump levels is 13 days so that the
       corresponding tapes can be recycled two weeks after their creation. The expiration dates for all full dump levels is 27 days so that the
       corresponding tapes can be recycled four weeks after their creation.

PRIVILEGE REQUIRED
       The issuer must be listed in the /etc/openafs/server/UserList file on every machine where the Backup Server is running, or must be logged
       onto a server machine as the local superuser "root" if the -localauth flag is included.
