|

|
|
<div><p>The CPYOPT command does not allow you to specify an ending date
|
||
|
|
and time. The system always uses the date and time of the copy request as
|
||
|
|
the ending date and time. </p>
|
||
|
|
<p>Therefore, the system uses the date and time of the request for the complete
|
||
|
|
ending date and time for a backup directory or volume.</p>
|
||
|
|
<div class="p">The ending date and time of a Complete Backup Range for an optical backup
|
||
|
|
volume or directory is one of the following conditions:<ul><li>The last time a CPYOPT command completed.</li>
|
||
|
|
<li>When the system successfully copies all eligible files in that volume
|
||
|
|
or directory.</li>
|
||
|
|
<li>When the starting date and time of the request is not after the existing
|
||
|
|
complete range.</li>
|
||
|
|
</ul>
|
||
|
|
</div>
|
||
|
|
<p>The definition of the ending date and time field has two parts. First,
|
||
|
|
this date is the last time a CPYOPT command completed for the directory or
|
||
|
|
volume with no failures. Second, the complete ending date and time will not
|
||
|
|
update if the range of the request does not overlap the existing range. This
|
||
|
|
is true even if all eligible files copy successfully. </p>
|
||
|
|
<p>Ending Date and Time — Scenario: On 1 July 1999, the user issued the CPYOPT
|
||
|
|
command for directory /DIR1 that specifies 1 February 1999 as the starting
|
||
|
|
date. If all eligible files successfully copy, the system sets the complete
|
||
|
|
starting date for the backup directory /DIR1 to 1 February 1999. The system
|
||
|
|
sets the complete ending date to 1 July 1999.</p>
|
||
|
|
<p>Now, the system issues a second CPYOPT command for directory /DIR1 on 15
|
||
|
|
September 1999, specifying 1 June 1999 as the starting date. If all eligible
|
||
|
|
files successfully copy, the complete starting date for backup directory /DIR1
|
||
|
|
remains 1 February 1999. The complete ending date is moved out to 15 September
|
||
|
|
1999. This is the normal situation that takes into account only the first
|
||
|
|
part of the definition above.</p>
|
||
|
|
<p>On 1 December 1999, the user issues the CPYOPT command again for the /DIR1
|
||
|
|
directory. This time the use specifies 1 October 1999 as the starting date.
|
||
|
|
Even if all eligible files copy successfully, the complete range will not
|
||
|
|
change. The complete range cannot be expanded to include the new ending date.
|
||
|
|
This is because the files that were created or changed between 15 September
|
||
|
|
1999 and 1 October 1999 are not accounted for.</p>
