I have tried the tar method:
# cd /var
# tar -cf - . ; (cd /var-new; tar xpf -)
... and got a load of warning messages to the effect of 'socket not
copied' for some files belonging to amavis and postfix. Looking
/usr/share/doc/tar-1.13.17/NEWS, I find that tar no longer archives
sockets. I have tried cp -a, but there were a few problems there
too. I will try again and see if I can nail the errors.
This raises a question: I'm about to get into backup, probably to
tape. I was going to use tar, but how can I backup partitions that may
contain sockets?
