I am using dump command to backup data on tape. But estimated and backed up data through dump command is more than the existing used data on MKT volume
in dump log file it show estimated 2154459967 KB(2054GB ) of data to be backed up instead of this actual used data is 1459GB + 7GB snapshot.
#df -h MKT
Filesystem total used avail capacity Mounted on
/vol/MKT/ 2823GB 1450GB 1372GB 52% /vol/MKT/

Hi kent what I observe is that MKT volume is showing 610 GB saved space through df -sh .. Can it be the reason the estimated dump size is more 1450+610 (2060GB) that actual used size ??????
