The STRANGE message is generally nothing harmful. It means that the 
backup program exited with non-standard but non-fatal error code. See 
below for details:

> ? gtar: ./notesdata/mail/sdelamoc.nsf: file changed as we read it
> ? gtar: ./notesdata/mail/spaxtonl.nsf: file changed as we read it
> ? gtar: ./notesdata/mail/xguardio.nsf: file changed as we read it

So the mail arrived to these mailboxes while they were being read by 
gtar. You can check with amrecover whether these files were backed up. 
I use dump for backup myself so I don't know about gtar, but I'd guess 
you're OK.

BTW, please accept my sincere sympathy for running Lotus Domino :-)
