Duplicate Fails - Did I get valid data?

Hi All,

I have been running a very large duplicate job for a large Dedup repository onto tape, this has been running for over a week.

The Job has completed with the following error, V-79-57344-1541

All I want to know is has my valid data been duplicated onto tape? (and simply the deleted data skipped).

From the look of the logs I can see lots of Backup sets that have been started and completed with no error's, however at the end of the log it states

"The requested media was mounted, but it has been erased and does not contain any backup sets" ( I have hundred's of dedup media sets in this job)

If it finds a Media set that is not valid does it skip and continue or fail the job?

Thanks

Bernie
