We are doing ha, but they want backups done to a usb drive.

I am using Debian Etch and the stock kernel.

You are right. I was advised to used rc3 to "fix" the problem. Thanks
for the reality check.

I am hoping that kernel 220.127.116.11 will do what I need. I am copying a
large file off the usb drive right now. So far, so good. When I get some
