I´am backing up my Netware 6.5 SP6 Server every night at one o´clock with tsafs /gwenable=yes and sbcon. A month ago I got an abend every friday so I thought that it was the tape. I changed it but it did not help very much. Last month I had no abend until yesterday, where the server was halted during backup again. In my abendlog is always kav.nlm from the integrated Gwava Kaspersky listed. I attached the last abendlog and hope that someone can help me with this.
