25 <P><STRONG>Purpose</STRONG>
26 <P>Displays a volume's dump history from the Backup Database
27 <P><STRONG>Synopsis</STRONG>
28 <PRE><B>backup volinfo -volume</B> <<VAR>volume name</VAR>>

33 <P><STRONG>Description</STRONG>
34 <P>The <B>backup volinfo</B> command displays a dump history of the
35 specified volume, reporting information such as the date on which the volume
36 was dumped and the tapes that contain it. Include the
37 <B>.backup</B> extension on the volume name if the backup version
38 of the volume was dumped.
39 <P><STRONG>Options</STRONG>
42 </B><DD>Names the volume for which to display the dump history. Include
43 the<TT> .backup</TT> or <TT>.readonly</TT> extension if the
44 backup or read-only version of the volume was dumped.
46 </B><DD>Constructs a server ticket using a key from the local
47 <B>/usr/afs/etc/KeyFile</B> file. The <B>backup</B> command
48 interpreter presents it to the Backup Server, Volume Server and VL Server
49 during mutual authentication. Do not combine this flag with the
50 <B>-cell</B> argument. For more details, see the introductory
51 <B>backup</B> reference page.
53 </B><DD>Names the cell in which to run the command. Do not combine this
54 argument with the <B>-localauth</B> flag. For more details, see the
55 introductory <B>backup</B> reference page.
57 </B><DD>Prints the online help for this command. All other valid options
60 <P><STRONG>Output</STRONG>
61 <P>The output includes a line for each Backup Database dump record that
62 mentions the specified volume, order from most to least recent. The
63 output for each record appears in a table with six columns:
65 <P><DT><B><TT>dumpID</TT>
66 </B><DD>The dump ID of the dump that includes the volume.
67 <P><DT><B><TT>lvl</TT>
68 </B><DD>The depth in the dump hierarchy of the dump level at which the volume was
69 dumped. A value of <TT>0</TT> indicates a full dump. A value
70 of <TT>1</TT> or greater indicates an incremental dump made at the specified
71 depth in the dump hierarchy.
72 <P><DT><B><TT>parentid</TT>
73 </B><DD>The dump ID of the dump's parent dump. A value of <TT>0</TT>
74 indicates a full dump, which has no parent; in this case, the value in
75 the <TT>lvl</TT> column is also <TT>0</TT>.
76 <P><DT><B><TT>creation date</TT>
77 </B><DD>The date and time at which the Backup System started the dump operation
78 that created the dump.
79 <P><DT><B><TT>clone date</TT>
80 </B><DD>For a backup or read-only volume, the time at which it was cloned from its
81 read/write source. For a read/write volume, the same as the value in
82 the <TT>creation date</TT> field.
83 <P><DT><B><TT>tape name</TT>
84 </B><DD>The name of the tape containing the dump: either the permanent tape
85 name, or an AFS tape name in the format
86 <I>volume_set_name</I>.<I>dump_level_name</I>.<I>tape_index</I>
87 where <I>volume_set_name</I> is the name of the volume set associated with
88 the initial dump in the dump set of which this tape is a part;
89 <I>dump_level_name</I> is the name of the dump level at which the initial
90 dump was backed up; <I>tape_index</I> is the ordinal of the tape in
91 the dump set. Either type of name can be followed by a dump ID in
92 parentheses; if it appears, it is the dump ID of the initial dump in the
93 dump set to which this appended dump belongs.
95 <P><STRONG>Examples</STRONG>
96 <P>The following example shows part of the dump history of the Backup volume
97 <B>user.smith.backup</B>:
