Using amanda to do our backups, we seem to get two or three evening's backup runs without problems, then the amverify read-back starts failing about half way down the tape with this type of error. The only solution appears to be a reboot. As this machine is also our main file server, I would dearly like to find a cure to this. Any pointers as to what to look for would be most welcome.
