[rdiff-backup-users] More on failures to SMB-mounted disk

[Keith Edmunds]

Ben, I have a little more information on the problems I was having
backing up to an SMB-mounted disk.

Firstly, soft links are definitely a problem, causing the following:

======================================
SpecialFileError httpd/htdocs/manual [Errno 1] Operation not permitted
UpdateError httpd/htdocs/manual Updated mirror temp file
/backups/zaphod/home/httpd/htdocs/rdiff-backup.tmp.33 does not match
source
======================================

Secondly, at the end of a backup (even one without soft links in the
source) I get the following (but note that the backup does seem to run
OK to completion before finishing like this):

======================================
mhlgengs001 site-packages # rdiff-backup --windows-mode /home
/backups/zaphod/home 

Traceback (most recent call last):

Finally, if I try to perform another backup after the above failure, I
get:

======================================

This last error looks like a problem setting the date/time of a file. 

Is there anything I can do to help resolve these problems?
