SafeGuarded backup allocation using a pool concept

Customer is running Safe Guarded backups for a month (31 days) worth of backups on a daily schedule. They have around 3500 volumes. Many of these are involved in DB2 and ADBAS databses. These database volumes (as well as some system volumes) undergo irregular Reogs. These reorgs cause them to see a change rate of almost 90% for some volumes. When these handful of volumes have high change rate, the backups cause old backup to roll off to craete more space for new backups. The client's average change rate is below 5%, but the exceptional change rate for a handful random volumes cause these backup roll offs.
If the design of the Safe Guarded capacity usage is like ESE pool (created form the individual volume multipliers) then at any given time, if a volume changes few times at much higher rate, there will be space in the pool due to majority of volumes changing at lower rate, in the ESE pool. Therefore will NOT cause the whole SG backup to roll off.

At 5% change rate the multipliers should be 2. But even with a multiplier of 8 we can only get12 to 14 backups before they start failing. We may now have to set Multipliers to 20 or higher.

    Declined. We expect to resolve this issue when another RFE #86182 (LCP : Dynamic Management (increase and decrease) of Safeguarded Capacity) is implemented. This will alleviate the need for this request.
