A drive on an NT 4 fileserver which was mapped to a RAID unit containing
about 120 GB of data has been copied to a new RAID unit with greater
capacity. The data was copied using scopy using appropriate flags to
preserve permissions and modification dates. The original drive letter
was then re-assigned to the copy of the data.

Unfortunately, it now looks like TSM ( client 5.1.0.1 , server 5.1.6.3 )
is backing up everything in the drive again. With a throughput of
only about 1 GB an hour, it looks like it is going to take several days
to complete.

Is there anyway to persuade TSM that that it already has the data ?
Is it because the drive itself has a new modification date that
everything else underneath is seen as new ?
