[net.micro.pc] Backup problems on DOS version 3

[food for line eater]

I seem to remember some discussion about bugs in BACKUP/RESTORE on PCDOS
version  3. I  looked  back  but  can't  find it. I now want to use this
version of DOS (I got it some time ago but  for  various  reasons  never
started  using it). Could some kind soul please let me have a summary of
the info (if it isn't too long, it might be worth posting it anyway).

Specifically:

    * What are the symptoms of the bug?

    * Are there any patches etc? Do dealers have any (esp. in the UK?)

    * Is it fixed in 3.10?

Thanks,
--

The bug I have observed is that when a file on the hard disk has the 
read-only bit set (i.e. is marked as read-only) and backing it up causes
it to span over more than one disk, the restore is corrupt.  I don't
know if the problem occurs in backup or restore.  (Does it matter from
a practical viewpoint?)  The only way I have found to live with this is
to simply not use the read-only bit.  This is inconvenient for me because
untrained people use my PC but what else can I do?  I discovered the bug
when part of my database was lost.  I managed to fix it, but not thanks
to DOS.
