Hi Steve,

I don't think any users have had trouble with --exclude-sockets
recently. From what I can tell, any further errors after using that
option were entirely unrelated to sockets.


If you are seeing SpecialFileError's, those errors should be
recoverable. That is, rdiff-backup does finish correctly, doesn't it? If
it does, then you have nothing to worry about, and can indeed continue
*without* using the --exclude-sockets option. What happens is this:
rdiff-backup tries to make the socket, encounters the AF_UNIX error,
recovers by storing information about the socket in the mirror_metadata,
and then logs the SpecialFileError. On restore, rdiff-backup will
attempt to recreate the socket by using the stored metadata.

If rdiff-backup is *not* finishing correctly, please send the complete
error message, as it is most likely not due to the AF_UNIX message.


Please see http://www.nongnu.org/rdiff-backup/error_policy.html

Best,
Andrew
