IBM Tivoli Storage FlashCopy Manager Tutorial
while IBM Tivoli Storage FlashCopy Manager still does not support Netbackup, I would expect it to support it in the near future. As IBM Tivoli Storage FlashCopy Manager is the replacement for IBM Copy Services for TSM as you can find out at:
IBM Copy Services support Netbackup & work will with it. If you can't wait till support is added to FlashCopy Manager you will be able to check IBM Copy Services & how they integrate with Netbackup as these already there.
If you have already purchased the NetApp & stuck with it, I am hoping IBM will release a FlashCopy Manager version that support NetApp as IBM OEM NetApp boxes under the name of Nseries. Though there still no official news about this.
If you have figured out how to integrate Netbackup with NetAPP SnapManager post it back, as I will be interested to find out how you did it. As it seemed not working while NetApp has provided our POC.
