<div class="section"><h4 class="sectiontitle">Saving from a second system</h4><p>Some technologies, such

as replication, make available a second copy of the data that can be used
|

|
|
to shift the save window from the primary copy to the secondary copy. This
|

technique can eliminate the backup window on the primary system. Therefore,

it does not affect production since the backup processing is done on a second

(ESS) provides enhanced storage capabilities. This technology uses the ESS

function of FlashCopy on

an independent disk pool. A single ESS server creates a point-in-time version
|
||
|

of the independent disk pool where the host is not aware of the copy. The
|

toolkit enables bringing the copy on to the backup system to perform saves

or other processing. For information on IBM TotalStorage (ESS) and its features,
