|

|
|
<div><p>Below are two scenarios using the CPYOPT command: Copy all files
|
|||
|
|
from the source volume and copy all files form the source volume since the
|
|||
|
|
last copy request.</p>
|
|||
|
|
<p><strong>Scenario 1 — Copy all files from the source volume:</strong> This example
|
|||
|
|
shows how to copy all files from the source volume VOL001 to a volume which
|
|||
|
|
currently does not contain any files or directories. The system will process
|
|||
|
|
all subdirectories of the source volume, create the subdirectories on the
|
|||
|
|
target volume, and copy all files.</p>
|
|||
|
|
<pre> > CPYOPT FROMVOL(VOL001) FROMPATH(/) TOVOL(CPYVOL001) SLTFILE(*ALL) CPYSUBDIR(*YES) CRTDIR(*YES) </pre>
|
|||
|
|
<p><strong>Scenario 2 — Copy all files form the source volume since the last copy
|
|||
|
|
request:</strong> For this example you have several different options
|
|||
|
|
which may take different lengths of time. Your first option would be to issue
|
|||
|
|
the same request as Scenario 1 but with a different target volume. The system
|
|||
|
|
will copy all the files and directories to the new target volume. </p>
|
|||
|
|
<p>Your second option would be to use the *CHANGED option on the SLTFILE parameter. </p>
|
|||
|
|
<pre>> CPYOPT FROMVOL(VOL001) FROMPATH(/) TOVOL(CPYVOL001) SLTFILE(*CHANGED) CPYSUBDIR(*YES) CRTDIR(*YES) </pre>
|
|||
|
|
<p>Depending on how many files are currently on the source and target media
|
|||
|
|
this request may take a long time to process. First, you must obtain a list
|
|||
|
|
of all files on the source media and the target media. Then compare the files
|
|||
|
|
in order to determine if any file has changed since the last CPYOPT request.
|
|||
|
|
Once that is done, the system will copy only the files that have changed. </p>
|
|||
|
|
<p>The third option is using the *NEW option on the SLTFILE parameter, provided
|
|||
|
|
that no existing files changed, but simply added to the source volume.</p>
|
|||
|
|
<pre> > CPYOPT FROMVOL(VOL001) FROMPATH(/) TOVOL(CPYVOL001) SLTFILE(*NEW) CPYSUBDIR(*YES) CRTDIR(*YES) </pre>
|
|||
|
|
<p>First, you must build option a list of all files that are on both the source
|
|||
|
|
and the target volume. Then compare the files before copying any new files.
|
|||
|
|
Your fourth option would be to use one of the SLTFILE options in combination
|
|||
|
|
with specifying a starting date and time.</p>

<pre>> CPYOPT FROMVOL(VOL001) FROMPATH(/) TOVOL(CPYVOL001) SLTFILE(*CHANGED) CPYSUBDIR(*YES) CRTDIR(*YES) FROMTIME(’04/01/99’ ’00:00:00’)</pre>
|
|||
|
|
<p> By specifying a starting time, the system copies only files that were
|
|||
|
|
created or changed after 04/01/99 to the target volume.</p>
