Thanks Carl, This was good advice. I tried a number of your approaches
like a manual dump and using rsyncd and even set up a new data directory
for Backuppc to eliminate filesystem corruption, but nothing worked.
Then I did a manual dump as you suggested again but this time I used the
IP address of the host rather then the host name and it worked!
It turned out that by changing the order of my host resolution in samba
config I could resolve the problem. I now use: "name resolve order =
wins lmhosts host bcast". Originally I had 'host' and 'wins' round the
other way. I do not know for sure what the mechanism for the failure was
but I think that it could have been a name resolution time out as I
noticed that name resolution for samba hosts is now much faster.
Thanks for your help again.
Manu.
