Hi Pro's
I have a question regarding NDMP backup. I backup a Netapp volume snapshot of the size 4921GB via NDMP. I have virtualfilespaces and my datamover set up. Some volumes backup much more data to the storage pool than the actual size of the volume. How is this possible? Can anyone explain?
Df -h size of volume in netapp:
Filesystem total used avail capacity Mounted on
/vol/myvfiler4647_vol1/ 8192GB 4921GB 2052GB 75% /vol/myvfiler4647_vol1/
/vol/myvfiler4647_vol1/.snapshot 0GB 162GB 0GB ---% /vol/myvfiler4647_vol1/.snapshot
TSM virtualfs path:
tsm: MYTSMSERV4250>q virtualfs myfiler /myvfiler4647_vol1
Node Name Virtual Filespace Filespace Path Hexadecimal
Mapping Name Name Path?

I get 7,777,958,297,600 bytes to 7244GB
How is this possible?
