11.7.50058 cannot validate tape backup
Backup windows 10 Version 1607 WS to LTO-2 tape drive.
Backup completes fine, but attempting to validate the archive results in a failure after a random time period between 0 and 5 minutes. Fails after a different amount of data read from the tape on each validation attempt. Doing another full BU to another tape and then attempting to validate that fails in exactly the same way.
The tape drive and tape are both in excellent health as far as HP Library and Tape Tools are concerned. Tape drive full test was run with NO errors.

I've not yet tried to restore the backup to another drive (my next step).

That was interesting.
As I couldn't do a stand-alone backup booted from the CD because it's an evaluation copy, I thought I'd try to run a stand-alone validate of the tape backup that I took using the product installed under Windows (that would neither validate nor restore).
It took me a while to work out that I needed to do a "re-scan" to be able to validate that archive.
Once I'd done that however, the entire backup tape validated without a problem, so it looks like the Windows code to read LTO archives is broken as well as the code that restores the partitions to the wrong location. So far so not impressed.

Hmmm re-downloaded, reinstalled, retried backup followed by validate and this time it works????
Maybe it was a bad install image? Though if that was the case, I'm surprised that wasn't detected during the installation.
Unless the latest Windows update fixed something ????
Odd indeed.
"All's well that ends well" as they say.

Hello David,
Thank you for feeding back! Should you face any issues with recovery, I'd recommend reporting this to Acronis support team.
