| Subject: | [rdiff-backup-users] Error When Backing up to samba share on ubuntu 8.10 via smbfs on Mac OS X |

| I've tried several versions of rdiff-backup (up through 1.3.3) and several versions of Python (up through 2.6.1). I believe the issues relates to symbolic links based on the error. It seems to fail when doing its destination capability tests when it fails to delete the temp symlink. When I go and look at what rdiff-backup creates before dying the file "/Volumes/For_Rent/Desktop/rdiff-backup-data/rdiff-backup.tmp.0/symlinked_file2" is a broken symlink to a file "symlinked_file1" that doesn't exist. Backups over SSH, using sshfs and MacFUSE, and to the local HD all work fine. So this seems like a strange interaction between rdiff-backup and Samba. Whenever I try to perform a backup to the samba share on my fileserver over smbfs from my Macbook I get the following error: Nathans-MacBook:~ nathan$ rdiff-backup --force -v5 ~/Desktop/ /Volumes/For_Rent/Desktop/ Using rdiff-backup version 1.2.2 Unable to import module posix1e from pylibacl package.
