<div><p>Reducing your save-outage time is the easiest way to use the save-while-active
|

function. When you use this option, the restore procedure is the same as when

you perform a standard save. In addition, you can use the save-while-active
|
||
|
|
function to reduce your save-outage time without using journaling or commitment
|

control. Unless you have no tolerance for a save-outage time, you should use

Use this option only if you have no tolerance for a save-outage time. You

should use the save-while-active function to eliminate your save-outage time
|

|
|
only for objects that you protect with journaling or commitment control. In
|
||
|
|
addition you will have considerably more complex recovery procedures. You

should consider these more complex recovery procedures in your disaster recovery

<div><p>This topic may help you decide how the save-while-active function
|
||
|
|
fits into your backup and recovery plan. Review your applications. Other procedures
|

|
|
that you use in your backup and recovery strategy still apply. You should
|
||
|
|
still consider them when you review your backup and recovery procedures. You
|
||
|
|
may conclude one of the following:</p>
|
||
|
|
<ul><li>Your current save strategy is adequate for your scheduled save-outage
|
||
|
|
time.</li>
|
||
|
|
<li>Critical application libraries are candidates for save-while-active processing.</li>
|
||
|
|
<li>Your critical application libraries are candidates, but may require modification
|
||
|
|
to minimize recovery procedures.</li>
|
||
|
|
<li>Critical documents or folders are candidates.</li>
|
||
|
|
<li>All application libraries are candidates because of a compressed save-outage
|
||
|
|
time.</li>
|
||
|
|
<li>You will use save-while-active to reduce your save-outage time because
|
||
|
|
you can tolerate a small save outage time.</li>
|
||
|
|
<li>You will use save-while-active to eliminate your save-outage time for
|
||
|
|
the following reasons: <ul><li>You have no tolerance for a save-outage time.</li>
|
||
|
|
<li>You are already using journaling and commitment control.</li>

<li>You plan to use journaling and commitment control.</li>
