</PRE>
|
||
|
|
<P><STRONG>Description</STRONG>
|
||
|
|
<P>The <B>backup setexp</B> command sets or changes the expiration date
|
||
|
|
associated with each specified dump level, which must already exist in the
|
||
|
|
dump hierarchy.
|
||
|
|
<P>Use the <B>-expires</B> argument to associate an expiration date with
|
||
|
|
each dump level. When the Backup System subsequently creates a dump at
|
||
|
|
the dump level, it uses the specified value to derive the dump's
|
||
|
|
expiration date, which it records on the label of the tape (or backup data
|
||
|
|
file). The Backup System refuses to overwrite a tape until after the
|
||
|
|
latest expiration date of any dump that the tape contains, unless the
|
||
|
|
<B>backup labeltape</B> command is used to relabel the tape. If a
|
||
|
|
dump level does not have an expiration date, the Backup System treats dumps
|
||
|
|
created at the level as expired as soon as it creates them.
|
||
|
|
<P>(Note that the Backup System does not automatically remove a dump's
|
||
|
|
record from the Backup Database when the dump reaches its expiration date, but
|
||
|
|
only if the tape that contains the dump is recycled or relabeled. To
|
||
|
|
remove expired and other obsolete dump records, use the <B>backup
|
||
|
|
deletedump</B> command.)
|
||
|
|
<P>Define either an absolute or relative expiration date:
|
||
|
|
<UL>
|
||
|
|
<P><LI>An absolute expiration date defines the month/day/year (and, optionally,
|
||
|
|
hour and minutes) at which a dump expires. If the expiration date
|
||
|
|
predates the dump creation time, the Backup System immediately treats the dump
|
||
|
|
as expired.
|
||
|
|
<P><LI>A relative date defines the number of years, months, or days (or a
|
||
|
|
combination of the three) after the dump's creation that it
|
||
|
|
expires. When the Backup System creates a dump at the dump level, it
|
||
|
|
calculates an actual expiration date by adding the relative date to the start
|
||
|
|
time of the dump operation.
|
||
|
|
</UL>
|
||
|
|
<P>If the command is used to change an existing expiration date associated
|
||
|
|
with a dump level, the new date applies only to dumps created after the
|
||
|
|
change. Existing dumps retain the expiration date assigned at the time
|
||
|
|
they were created.

||

|
||
|
|
<DL>
|
||
|
|
<P><DT><B>-dump
|
||
|
|
</B><DD>Specifies the full pathname of each dump level to assign the expiration
|
||
|
|
date specified by the <B>-expires</B> argument.
|
||
|
|
<P><DT><B>-expires
|
||
|
|
</B><DD>Defines the absolute or relative expiration date to associate with each
|
||
|
|
dump level named by the <B>-dump</B> argument. Absolute expiration
|
||
|
|
dates have the following format:
|
||
|
|
<P>
|
||
|
|
<PRE> [<B>at</B>] {<B>NEVER</B> | <VAR>mm</VAR><B>/</B><VAR>dd</VAR><B>/</B><VAR>yyyy</VAR> [<VAR>hh</VAR><B>:</B><VAR>MM</VAR>] }
|
||
|
|
|
||
|
|
</PRE>
|
||
|
|
<P>where the optional word <B>at</B> is followed either by the string
|
||
|
|
<B>NEVER</B>, which indicates that dumps created at the dump level never
|
||
|
|
expire, or by a date value with a required portion (<VAR>mm</VAR> for month,
|
||
|
|
<VAR>dd</VAR> for day, and <VAR>yyyy</VAR> for year) and an optional portion
|
||
|
|
(<VAR>hh</VAR> for hours and <VAR>MM</VAR> for minutes).
|
||
|
|
<P>Omit the <VAR>hh</VAR>:<VAR>MM</VAR> portion to use the default of
|
||
|
|
midnight (00:00 hours), or provide a value in 24-hour format (for
|
||
|
|
example, <B>20:30</B> is 8:30 p.m.).
|
||
|
|
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 February 2038. The command interpreter
|
||
|
|
automatically reduces later dates to the maximum value.
|
||
|
|
<P>Relative expiration dates have the following format:
|
||
|
|
<PRE> [<B>in</B>] [<VAR>years</VAR><B>y</B>] [<VAR>months</VAR><B>m</B>] [<VAR>days</VAR><B>d</B>]
|
||
|
|
|
||
|
|
</PRE>
|
||
|
|
<P>
|
||
|
|
<P>where the optional word <B>in</B> is followed by at least one of a
|
||
|
|
number of years (maximum <B>9999</B>) followed by the letter <B>y</B>,
|
||
|
|
a number of months (maximum <B>12</B>) followed by the letter
|
||
|
|
<B>m</B>, or a number of days (maximum <B>31</B>) followed by the
|
||
|
|
letter <B>d</B>. If providing more than one of the three, list them
|
||
|
|
in the indicated order. If the date that results from adding the
|
||
|
|
relative expiration value to a dump's creation time is later than the
|
||
|
|
latest possible date in the UNIX time representation, the Backup System
|
||
|
|
automatically reduces it to that date.
