-</PRE>
-<P><STRONG>Description</STRONG>
-<P>The <B>backup deletedump</B> command deletes one or more dump records
-from the Backup Database. Either use the <B>-dumpid</B> argument to
-specify the dump ID number of one or more dumps, or use the <B>-from</B>
-and <B>-to</B> arguments to delete the records for all regular dumps
-created during the time period bracketed by the specified values.
-<P>Use this command to remove dump records that are incorrect (possibly
-because a dump operation was interrupted or failed), or that correspond to
-dumps that are expired or otherwise no longer needed.
-<P><STRONG>Cautions</STRONG>
-<P>The only way to remove the dump record for an appended dump is to remove
-the record for its initial dump, and doing so removes the records for all of
-the initial dump's associated appended dumps.
-<P>The only way to remove the record for a Backup Database dump (created with
-the <B>backup savedb</B> command) is to specify its dump ID number with
-the <B>-dumpid</B> argument. Using the <B>-from</B> and
-<B>-to</B> arguments never removes database dump records.
-<P>Removing records of a dump makes it impossible to restore data from the
-corresponding tapes or from any dump that refers to the deleted dump as its
-parent, directly or indirectly. That is, restore operations must begin
-with the full dump and continue with each incremental dump in order. If
-the records for a specific dump are removed, it is not possible to restore
-data from later incremental dumps unless the deleted records are restored by
-running the <B>backup scantape</B> command with the <B>-dbadd</B>
-flag.
-<P>If a dump set contains any dumps that were created outside the time range
-specified by the <B>-from</B> and <B>-to</B> arguments, the command
-does not delete any of the records associated with the dump set, even if some
-of them represent dumps created during the time range.
-<P><STRONG>Options</STRONG>
-<DL>
-<P><DT><B>-dumpid
-</B><DD>Specifies the dump ID of each dump record to delete. The
-corresponding dumps must be initial dumps; it is not possible to delete
-appended dump records directly, but only by deleting the record of their
-associated initial dump. Using this argument is the only way to delete
-records of Backup Database dumps (created with the <B>backup savedb</B>
-command).
-<P>Provide either this argument or the <B>-to</B> (and optionally
-<B>-from</B>) argument.
-<P><DT><B>-from
-</B><DD>Specifies the beginning of a range of dates; the record for any dump
-created during the indicated period of time is deleted.
-<P>Omit this argument to indicate the default of midnight (00:00 hours)
-on 1 January 1970 (UNIX time zero), or provide a date value in the format
-<VAR>mm/dd/yyyy</VAR> [<VAR>hh:MM</VAR>]. The month (<VAR>mm</VAR>),
-day (<VAR>dd</VAR>), and year (<VAR>yyyy</VAR>) are required. The hour and
-minutes (<VAR>hh</VAR>:<VAR>MM</VAR>) are optional, but if provided must be
-in 24-hour format (for example, the value <B>14:36</B> represents
-2:36 p.m.). If omitted, the time defaults to
-midnight (00:00 hours).
-<P>The <B>-to</B> argument must be provided along with this one.
-<TABLE><TR><TD ALIGN="LEFT" VALIGN="TOP"><B>Note:</B></TD><TD ALIGN="LEFT" VALIGN="TOP">A plus sign follows this argument in the command's syntax statement
-because it accepts a multiword value which does not need to be enclosed in
-double quotes or other delimiters, not because it accepts multiple
-dates. Provide only one date (and optionally, time) definition.
-</TD></TR></TABLE>
-<P><DT><B>-to
-</B><DD>Specifies the end of a range of dates; the record of any dump created
-during the range is deleted from the Backup Database.
-<P>Provide either the value <B>NOW</B> to indicate the current date and
-time, or a date value in the same format as for the <B>-from</B>
-argument. Valid values for the year (<VAR>yyyy</VAR>) range from
-<B>1970</B> to <B>2037</B>; higher values are not valid because
-the latest possible date in the standard UNIX representation is in February
-2038. The command interpreter automatically reduces any later date to
-the maximum value.
-<P>If the time portion (<VAR>hh:MM</VAR>) is omitted, it defaults to 59
-seconds after midnight (00:00:59 hours). Similarly, the
-<B>backup</B> command interpreter automatically adds 59 seconds to any
-time value provided. In both cases, adding 59 seconds compensates for
-how the Backup Database and <B>backup dumpinfo</B> command represent dump
-creation times in hours and minutes only. For example, the Database
-records a creation timestamp of <TT>20:55</TT> for any dump operation
-that begins 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.
-<P>Provide either this argument, or the <B>-dumpid</B> argument.
-This argument is required if the <B>-from</B> argument is provided.
-<P><B>Caution:</B> Specifying the value <B>NOW</B> for this
-argument when the <B>-from</B> argument is omitted deletes all dump
-records from the Backup Database (except for Backup Database dump records
-created with the <B>backup savedb</B> command).
-<TABLE><TR><TD ALIGN="LEFT" VALIGN="TOP"><B>Note:</B></TD><TD ALIGN="LEFT" VALIGN="TOP">A plus sign follows this argument in the command's syntax statement

-<P><DT><B>-localauth
-</B><DD>Constructs a server ticket using a key from the local
-<B>/usr/afs/etc/KeyFile</B> file. The <B>backup</B> command
-interpreter presents it to the Backup Server, Volume Server and VL Server
-during mutual authentication. Do not combine this flag with the
-<B>-cell</B> argument. For more details, see the introductory
-<B>backup</B> reference page.
-<P><DT><B>-cell
-</B><DD>Names the cell in which to run the command. Do not combine this
-argument with the <B>-localauth</B> flag. For more details, see the
-introductory <B>backup</B> reference page.
-<P><DT><B>-help
-</B><DD>Prints the online help for this command. All other valid options
-are ignored.
-</DL>
-<P><STRONG>Output</STRONG>
-<P>At the conclusion of processing, the output lists the dump IDs of all dump
-records deleted in the following format:
-<PRE> The following dumps were deleted:
- <VAR>dump ID 1</VAR>
- <VAR>dump ID 2</VAR>
- <VAR>etc.</VAR>
-
-</PRE>
-<P><STRONG>Examples</STRONG>
-<P>The following command deletes the dump record with dump ID 653777462, and
-for any appended dumps associated with it:
-<PRE> % <B>backup deletedump -dumpid 653777462</B>
- The following dumps were deleted:
- 653777462
-
-</PRE>
-<P>The following command deletes the Backup Database record of all dumps
-created between midnight on 1 January 1997 and 23:59:59 hours on
-31 December 1997:
-<PRE> % <B>backup deletedump -from 01/01/1997 -to 12/31/1997</B>
- The following dumps were deleted:
- 598324045
- 598346873
- ...
- ...
- 653777523
- 653779648
-
-</PRE>
-<P><STRONG>Privilege Required</STRONG>
-<P>The issuer must be listed in the <B>/usr/afs/etc/UserList</B> file on
-every machine where the Backup Server is running, or must be logged onto a
-server machine as the local superuser <B>root</B> if the
-<B>-localauth</B> flag is included.
