From what I read on the net, I must not be the only one who has experienced
ridiculous problems with 3.1 backup & restore.  My suggestion:  for backing
up whole disks the "Fastback" program beats anything else going;  it actually
uses the multi-channel DMA the PC has always been capable of i.e. reads from
the hard disk and writes to the floppy at the same time.  For normal uses
such as backing up one directory, the ordinary DOS "copy" is better EXCEPT 
when one needs to backup a file larger than 360K, typically a database file.
I have been using two brutish and simple-minded but effective little routines
I call "cut" and "join" to break such large files into 350K pieces, copy the
pieces onto floppies, and rejoin them elsewhere.  I've posted listings for  
these on net.sources.
