Well, I _did_ finally get so exasperated that I tried /etc/sysadmin
which calls 'backup' - the distribution inode-by-inode whole filesystem
at a time without choice of files backup method.

I figured 'How could it fail?' .... foolish me. It panicked, just like
all the other backup attempts did. Maybe there is a fault in the 2.2.1
high density floppy driver?

The only hack my kernel has (outside of number of buffers and system
name customization) is the public domain ptydriver, which I ran under
2.1.3 for a long time, and have been running in 2.2.1 since I 
upgraded.

Again I ask: has anyone else experienced this? Any help at all would
be appreciated - I have 80 megabytes of largely unbacked up data, and
I can't back it up!

Thanks
