Later tape technology like LTO carried out their own verification of the data as it wrote, so even then verify on the backup job was becoming superfluous. I'd like to know if there's anything inherent in how BE does backups to HDD and Dedupe that might make turning verify off less of a risk.
For example the dedupe process is pretty complex and I suspect there will be data verification during that. I doubt you are going to get an answer to your question. It is up to you to judge the risk vs. What I may do is disable verify and introduce a weekly backup readability test. Communities View more. Turn on suggestions.

Showing results for. This does not ensure the integrity of the files, it only ensures that the tape can be read. If the data that is being backed up on the hard disk is corrupt data, the data residing on the tape will be corrupt as well. This is true even with a successful verify operation. Figure 1 Write checksums to media is also selected by default Figure 1 and goes hand in hand with the verify operation.
During all tape write operations backup, archiving, etc. During all tape read operations catalog, restore, verify, etc. The checksums that are created are used in the verify process to make sure that the data is viable on the tape.
If this check box has been selected, backup performance may slightly be degraded because checksums are being calculated for each data stream and then written to tape immediately after the data stream.
If there is an error in the data, the checksums will not match and the software will report an error. Data is not compared to the original file on the volume or other source because many files will have changed between the time the backup of a specific file ends and the verify operation of that file begins.
This will cause many "false alarms" in verify, possibly causing real failures to be masked.
