Hi,

Please try the following. Edit /quadstorvtl/etc/quadstor.conf and add the following line

DebugLoad=1

Restart the system and you should be able to continue with the backups. In case the issue is seen again the above configuration will help identify the problem.

What most likely has happened is that due to the failed writes Veeam is probably finding an inconsistent metadata. You could try cataloging these tapes individually and then erase them if there is no meaningful data on them. Or you could simply write protect these tapes so that they are not used in the backups.

The problem you earlier faced isn't seen in the logs yet, but might come back later.
