Hi Kas,

From the log you have attached I can see that the problem is on channel t1.
Has the channel allocated successfully ?
It could be a media problem, did you try to use new media for the backup ?
Try to allocate the channels to disk instead of tape and see if the problem
presist.

I am having the same problem on a sporadic basis with multiple databases.
Any solution yet ? Wondering why the inconsistency, sometimes works sometimes
does not.

Thanks !!!
