|

<div><p>The starting date and time of a Complete Backup Range for an optical
|
||
backup volume or directory is the earliest time that is specified on a CPYOPT
|
||
command when all eligible files on the volume or directory were successfully
|
||
copied. </p>
|
||
<p>You can specify a starting date and time on the CPYOPT command. This system
|
||
uses time to select the files from the primary volume to copy to the optical
|
||
backup volume. The system copies any files that are created or changed on
|
||
or after this time. First, the system must successfully copy all eligible
|
||
files for a directory or volume. Then the system sets the starting date and
|
||
time for the corresponding optical backup volume or directory to the specified
|
||
time. The definition indicates that this value is the earliest time that is
|
||
specified on a CPYOPT command. Consider the following example. </p>
|
||
<p><strong>Scenario — Starting Date and Time:</strong>A user issues the CPYOPT command
|
||
for directory /DIR1 by specifying 1 May 1999 as the starting date. If all
|
||
eligible files successfully copy, then the system sets the complete starting
|
||
date for the backup directory /DIR1 to 1 May 1999.</p>
|
||
<p>Now assume that the user issues the CPYOPT command again for /DIR1. This
|
||
time the system sets the starting date to 1 April 1999. This request copies
|
||
any files that have changed since the last CPYOPT command. Additionally, it
|
||
copies any files that were created between 1 April 1999 and 1 May 1999 that
|
||
were not selected on the previous request. If all eligible files again copy
|
||
successfully, then the starting date for backup directory /DIR1 changes to
|
||
1 April 1999. Future copies specifying earlier starting dates would produce
|
||
similar results. </p>
|
||
<p>Use *BEGIN and *AVAIL for the starting date and time on the CPYOPT command.
|
||
This will copy all the files from a primary directory or volume, regardless
|
||
of the create or change time for the file.</p>
