<P><STRONG>Description</STRONG>
|
||
|
|
<P>The <B>vos dump</B> command converts the contents of the indicated
|
||
|
|
volume, which can be read/write, read-only or backup, into ASCII
|
||
|
|
format. The Volume Server writes the converted contents to the file
|
||
|
|
named by the <B>-file</B> argument, or to the standard output
|
||
|
|
stream. In the latter case, the output can be directed to a named pipe,
|
||
|
|
which enables interoperation with third-party backup utilities.
|
||
|
|
<P>To dump the complete contents of a volume (create a <I>full dump</I>),
|
||
|
|
omit the <B>-time</B> argument or specify the value <B>0</B> (zero)
|
||
|
|
for it. To create an <I>incremental dump</I>, which includes only
|
||
|
|
the files and directories in the volume that have modification timestamps
|
||
|
|
later than a certain time, specify a date and time as the value for the
|
||
|
|
<B>-time</B> argument.
|
||
|
|
<P>By default, the <B>vos</B> command interpreter consults the Volume
|
||
|
|
Location Database (VLDB) to learn the volume's location, so the
|
||
|
|
<B>-server</B> and <B>-partition</B> arguments are not
|
||
|
|
required. If the <B>-id</B> argument identifies a read-only volume
|
||
|
|
that resides at multiple sites, the command dumps the version from just one of
|
||
|
|
them (normally, the one listed first in the volume's VLDB entry as
|
||
|
|
reported by the <B>vos examine</B> or <B>vos listvldb</B>
|
||
|
|
command). To dump the read-only volume from a particular site, use the
|
||
|
|
<B>-server</B> and <B>-partition</B> arguments to specify the
|
||
|
|
site. To bypass the VLDB lookup entirely, provide a volume ID number
|
||
|
|
(rather than a volume name) as the value for the <B>-id</B> argument,
|
||
|
|
together with the <B>-server</B> and <B>-partition</B>
|
||
|
|
arguments. This makes it possible to dump a volume for which there is
|
||
|
|
no VLDB entry.
|
||
|
|
<P>During the dump operation, the volume is inaccessible both to Cache
|
||
|
|
Managers and to other volume operations. Dumping a volume does not
|
||
|
|
otherwise affect its status on the partition or its VLDB entry.
|
||
|
|
<P>To restore a dumped volume back into AFS, use the <B>vos restore</B>
|
||
|
|
command.
|
||
|
|
<P><STRONG>Cautions</STRONG>
|
||
|
|
<P>Support for incremental dumps is provided to facilitate interoperation with
|
||
|
|
third-party backup utilities. The <B>vos dump</B> command does not
|
||
|
|
provide any of the administrative facilities of an actual backup system, so
|
||
|
|
the administrator must keep manual records of dump times and the relationship
|
||
|
|
between full and incremental dumps of a volume. For a volume's
|
||
|
|
contents to be consistent after restoration of incremental dumps, there must
|
||
|
|
be no gap between the time at which a prior dump of the volume was created and
|
||
|
|
the value of the <B>-time</B> argument to the <B>vos dump</B> command
|
||
|
|
that creates the incremental dump. More specifically, for a read/write
|
||
|
|
volume, the <B>-time</B> argument must specify the time that the prior
|
||
|
|
dump was performed, and for a read-only or backup volume it must specify the
|
||
|
|
time that the volume was last released (using the <B>vos release</B>
|
||
|
|
command) or cloned (using the <B>vos backup</B> or <B>vos
|
||
|
|
backupsys</B> command) prior to dumping it. The parent dump can be
|
||
|
|
either a full dump or another incremental dump.
|
||
|
|
<P><STRONG>Options</STRONG>
|
||
|
|
<DL>
|
||
|
|
<P><DT><B>-id
|
||
|
|
</B><DD>Specifies either the complete name or volume ID number of the read/write,
|
||
|
|
read-only, or backup volume to dump.
|
||
|
|
<P><DT><B>-time
|
||
|
|
</B><DD>Specifies whether the dump is full or incremental. Omit this
|
||
|
|
argument to create a full dump, or provide one of three acceptable
|
||
|
|
values:
|
||
|
|
<UL>
|
||
|
|
<P><LI>The value <B>0</B> (zero) to create a full dump.
|
||
|
|
<P><LI>A date in the format
|
||
|
|
<VAR>mm</VAR><B>/</B><VAR>dd</VAR><B>/</B><VAR>yyyy</VAR> (month, day and
|
||
|
|
year) to create an incremental dump that includes only files and directories
|
||
|
|
with modification timestamps later than midnight (12:00
|
||
|
|
a.m.) on the indicated date. Valid values for the year
|
||
|
|
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 2038. The command interpreter automatically reduces later dates to
|
||
|
|
the maximum value. An example is <B>01/13/1999</B>.
|
||
|
|
<P><LI>A date and time in the format
|
||
|

<B>"</B><VAR>mm</VAR><B>/</B><VAR>dd</VAR><B>/</B><VAR>yyyy</VAR>
|
||
|
|
<VAR>hh</VAR><B>:</B><VAR>MM</VAR><B>"</B> to create an incremental
|
||
|
|
dump that includes only files and directories with modification timestamps
|
||
|
|
later than the specified date and time. The date format is the same as
|
||
|
|
for a date alone. Express the time as hours and minutes
|
||
|
|
(<VAR>hh</VAR>:<VAR>MM</VAR>) in 24-hour format (for example,
|
||
|
|
<B>20:30</B> is 8:30 p.m.). Surround the
|
||
|
|
entire expression with double quotes (" ") because it contains a space.
|
||
|
|
An example is <B>"01/13/1999 22:30"</B>.

this argument is omitted, the dump is directed to the standard output

|

|
|
<P>The following command writes an incremental dump of the volume

<B>smith.990131.dump</B> in the current working
|

|

|
||
|
|
the dump.

</PRE>
|

<P><STRONG>Privilege Required</STRONG>
|
||
|
|
<P>The issuer must be listed in the <B>/usr/afs/etc/UserList</B> file on
|

|
|
the machine specified with the <B>-server</B> argument and on each

the issuer must instead be logged on to a server machine as the local
