Question #241395 on Duplicity changed: https://answers.launchpad.net/duplicity/+question/241395
Description changed to: Goal: Use Duplicity to backup user directory on OS X laptop to at-home file server, using SSH. There are two machines in play: * Client (MElch2), a laptop running OS X 10.9.1. I used Homebrew to install Duplicity 0.6.22. Logged-in user is 'melissa', but I 'su'ed to user 'jonathan'. * Server (JElch4 at 192.168.10.100), a server running Ubuntu Linux with an SSH server. SSH user is also 'jonathan', who has write access to the target directory. Steps to reproduce: 1. Begin from a known state (empty cache and empty backup location) bash-3.2$ sudo rm -rf ~/.cache/duplicity/ 2. Set max open files bash-3.2$ ulimit -n 1024 3. Start backup bash-3.2$ sudo duplicity --no-encryption --ssh-askpass --use-scp --progress --exclude /Users/melissa/Dropbox /Users/melissa ssh://[email protected]//mnt/raid/bak/Melissa/MElch2/ 4. Show 'collection-status' bash-3.2$ sudo duplicity collection-status --no-encryption --ssh-askpass --use-scp ssh://[email protected]//mnt/raid/bak/Melissa/MElch2/ 5. Attempt to list files contained in backup bash-3.2$ sudo duplicity list-current-files --no-encryption --ssh-askpass --use-scp ssh://[email protected]//mnt/raid/bak/Melissa/MElch2/ Expected results (corresponds with step numbers above): 1. Cache deleted 2. Limit set 3. Backup succeeds 4. Collection status shows actual number of volumes (in my case, 3192) 5. All backed up files are listed Actual results (corresponds with step numbers above): 1. Cache deleted 2. Limit set 3. Backup succeeds 4. Collection status shows only 1287 volumes 5.
