BACKUP_SAVEDB(8)	     AFS Command Reference	      BACKUP_SAVEDB(8)

NAME
       backup_savedb - Creates a saved copy of the Backup Database

SYNOPSIS
       backup savedb [-portoffset <TC port offset>]
	   [-archive <date time>+] [-localauth]
	   [-cell <cell name>] [-help]

       backup sa [-p <TC port offset>]
	   [-a <date time>+]
	   [-l] [-c <cell name>] [-h]

DESCRIPTION
       The backup savedb command creates a backup copy of the entire Backup
       Database and writes it to the tape in the device controlled by the Tape
       Coordinator indicated with the -portoffset argument. If the database is
       damaged (as reported by the backup dbverify command), this command
       repairs as much of the corruption as possible as it creates the saved
       copy. The Backup Server creates a dump record for the saved database in
       the Backup Database (but in the disk version of the database only, not
       in the version written to tape).

       If the "FILE YES" instruction appears in the
       /usr/afs/backup/CFG_device_name file associated with the specified port
       offset, then the backup savedb command dumps the database copy to the
       backup data file listed for that port offset in the Tape Coordinator's
       /usr/afs/backup/tapeconfig file, instead of to tape. For the sake of
       clarity, the following text refers to tapes only, but the Backup System
       handles backup data files in much the same way.

       If the -archive flag is provided, after writing the saved copy of the
       database the Backup System truncates the copy of the database on disk
       by deleting volume dump records with timestamps prior to the specified
       date and time (it does not delete the dump records created by previous
       backup savedb commands, however).

       If the tape to which the database copy is written has an AFS tape name,
       it must be "Ubik_db_dump.1" or "<NULL>". Any permanent name is
       acceptable.

       The Tape Coordinator's default response to this command is to access
       the first tape by invoking the "MOUNT" instruction in the local
       /usr/afs/backup/CFG_device_name file, or by prompting the backup
       operator to insert the tape if there is no "MOUNT" instruction.
       However, if the "AUTOQUERY NO" instruction appears in the
       CFG_device_name file, or if the issuer of the butc command included the
       -noautoquery flag, the Tape Coordinator instead expects the tape to be
       in the device already.  If it is not, the Tape Coordinator invokes the
       "MOUNT" instruction or prompts the operator. It also invokes the
       "MOUNT" instruction or prompts for any additional tapes needed to
       complete the operation; the backup operator must arrange to provide
       them.

OPTIONS
       -portoffset <TC port offset>
	   Specifies the port offset number of the Tape Coordinator handling
	   the tapes for this operation.

       -archive <date time>+
	   Specifies a date and time; volume dump records with earlier
	   timestamps are deleted from the disk copy of the Backup Database
	   after the Backup System dumps the database (a dump's timestamp
	   appears in the "created" field of the output from the backup
	   dumpinfo command). However, if a dump set contains any dump created
	   after the specified date, none of the dump records associated with
	   the dump set are deleted. Dump records for previous dumps of the
	   database (created with the backup savedb command) are never
	   deleted; use the backup deletedump command to remove them.

	   Provide one of two values:

	   ·   The string "NOW" to indicate the current date and time, in
	       which case the Backup System deletes all dump records except
	       those for dumps of the Backup Database itself.

	   ·   A date value in the format mm/dd/yyyy [hh:MM]. The month (mm),
	       day (dd), and year (yyyy) are required, and valid values for
	       the year range from 1970 to 2037; higher values are not valid
	       because the latest possible date in the standard UNIX
	       representation is in February 2038. The Backup System
	       automatically reduces any later date to the maximum value.

	       The hour and minutes (hh:MM) are optional, but if provided must
	       be in 24-hour format (for example, the value "14:36" represents
	       2:36 p.m.). If omitted, the time defaults to 59 seconds after
	       midnight (00:00:59 hours). Similarly, the backup command
	       interpreter automatically adds 59 seconds to any time value
	       provided. In both cases, adding 59 seconds compensates for how
	       the Backup Database and backup dumpinfo command represent dump
	       creation times in hours and minutes only. That is, the Database
	       records a creation timestamp of "20:55" for any dump created
	       between 20:55:00 and 20:55:59. Automatically adding 59 seconds
	       to a time thus includes the records for all dumps created
	       during that minute.

       -localauth
	   Constructs a server ticket using a key from the local
	   /usr/afs/etc/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.

EXAMPLES
       The following example writes a copy of the Backup Database to the tape
       device controlled by the Tape Coordinator with port offset 1:

	  % backup savedb -portoffset 1

PRIVILEGE REQUIRED
       The issuer must be listed in the /usr/afs/etc/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.
