The current implementation will read all the data on the tape, but it will only compare the attributes to what is in the catalog. Thus the verify job will verify that the whole tape can be read and that all the files that are recorded in the catalog are actually on the tape, but it will not compare the data to what is on disk. Comparing the data on tape and disk is a future project ... > > Will the tape drive itself ensure that the data is verified during the > backup job (by a read-after-write verify)?
