20 <title>Description</title>
21 <para>The <emphasis role="bold">backup volinfo</emphasis> command displays a dump history of the specified
22 volume, reporting information such as the date on which the volume was
23 dumped and the tapes that contain it. Include the <computeroutput>.backup</computeroutput> extension on
24 the volume name if the backup version of the volume was dumped.</para>
28 <title>Options</title>
31 <term><emphasis role="bold">-volume</emphasis> <<emphasis>volume name</emphasis>></term>
33 <para>Names the volume for which to display the dump history. Include the
34 <computeroutput>.backup</computeroutput> or <computeroutput>.readonly</computeroutput> extension if the backup or read-only version of
35 the volume was dumped.</para>
40 <term><emphasis role="bold">-localauth</emphasis></term>
42 <para>Constructs a server ticket using a key from the local
43 <replaceable>/usr/afs/etc/KeyFile</replaceable> file. The <emphasis role="bold">backup</emphasis> command interpreter presents
44 it to the Backup Server, Volume Server and VL Server during mutual
45 authentication. Do not combine this flag with the <emphasis role="bold">-cell</emphasis> argument. For
46 more details, see <link linkend="backup8">backup(8)</link>.</para>
51 <term><emphasis role="bold">-cell</emphasis> <<emphasis>cell name</emphasis>></term>
53 <para>Names the cell in which to run the command. Do not combine this argument
54 with the <emphasis role="bold">-localauth</emphasis> flag. For more details, see <link linkend="backup8">backup(8)</link>.</para>
59 <term><emphasis role="bold">-help</emphasis></term>
61 <para>Prints the online help for this command. All other valid options are
70 <para>The output includes a line for each Backup Database dump record that
71 mentions the specified volume, order from most to least recent. The output
72 for each record appears in a table with six columns:</para>
78 <para>The dump ID of the dump that includes the volume.</para>
85 <para>The depth in the dump hierarchy of the dump level at which the volume was
86 dumped. A value of <computeroutput>0</computeroutput> indicates a full dump. A value of <computeroutput>1</computeroutput> or greater
87 indicates an incremental dump made at the specified depth in the dump
95 <para>The dump ID of the dump's parent dump. A value of <computeroutput>0</computeroutput> indicates a full
96 dump, which has no parent; in this case, the value in the <computeroutput>lvl</computeroutput> column is
97 also <computeroutput>0</computeroutput>.</para>
102 <term>creation date</term>
104 <para>The date and time at which the Backup System started the dump operation
105 that created the dump.</para>
110 <term>clone date</term>
112 <para>For a backup or read-only volume, the time at which it was cloned from its
113 read/write source. For a read/write volume, the same as the value in the
114 <computeroutput>creation date</computeroutput> field.</para>
119 <term>tape name</term>
121 <para>The name of the tape containing the dump: either the permanent tape name,
122 or an AFS tape name in the format
123 <emphasis>volume_set_name</emphasis>.<emphasis>dump_level_name</emphasis>.<emphasis>tape_index</emphasis> where
124 <emphasis>volume_set_name</emphasis> is the name of the volume set associated with the
125 initial dump in the dump set of which this tape is a part;
126 <emphasis>dump_level_name</emphasis> is the name of the dump level at which the initial dump
127 was backed up; <emphasis>tape_index</emphasis> is the ordinal of the tape in the dump
128 set. Either type of name can be followed by a dump ID in parentheses; if
129 it appears, it is the dump ID of the initial dump in the dump set to which
130 this appended dump belongs.</para>
