Commvault Intellisnap on IBM FLASHSYSTEM. Add SNAPSHOTS instead of FlashCopy

Good Day,

Commvaut Intellisnap is currently using FlashCopy.

This "Snap" feature is taking a clone of the volume so the scource volume is cloned at 100% of Space Usage on the array.

 

Since some time there is a new ( i call it new ) feature implemented which is taking SNAPSHOTS. This will take only track of the changed bocks and not a full CLONE/COPY of the volume.

 

"Spectrum Virtualize 8.5.1 added a new feature called Volume Groups Snapshots. This is a radically simpler method of taking snapshots than the current implementation of FlashCopy."

 

Is there a impementation ongoing by commvault to utilize this much more nice feature or any ETA on this? 

 

thanks

Good day Sebbo,

For several years we have two options with IBM Flash Copy, the second one Space-Efficient will take snapshots instead of clones. Not sure if this is what you are asking for.

Hi

i already did following but it seems that it’s always a clone of the whole LUN instead of a instant Snapshot
