Duplicity

rsync backend fails

Asked by Steven

My duplicity calls have started failing when using rsync. The problem goes back at least until November, which is as far as my logs seem to go. Using scp seems to work. For example, if I run the following:

    mkdir /tmp/testsource
    mkdir /tmp/testbackup
    touch /tmp/testsource/foo
    export PASSPHRASE="test"

    duplicity full /tmp/testsource scp://localhost//tmp/testbackup
    duplicity inc /tmp/testsource scp://localhost//tmp/testbackup
    duplicity inc /tmp/testsource rsync://localhost//tmp/testbackup

Everything works until the last command, at which point I get

    Attempt 1 failed. BackendException: Error running 'rsync -e 'ssh -oBatchMode=yes' /localhost//tmp/testbackup/': returned 23, with output:

    rsync: change_dir "/localhost//tmp/testbackup" failed: No such file or directory (2)
    rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1165) [sender=3.1.1]

I'm not sure where exactly the problem lies, but I suspect one of the underlying packages changed.
Thanks!

please try editing
 duplicity/backend.py
of your installation.

around line 75 you'll see

uses_netloc = ['ftp',
               'ftps',
               'hsi',
               's3',
               'scp', 'ssh', 'sftp',
               'webdav', 'webdavs',
               'gdocs',
               'http', 'https',
               'imap', 'imaps',
               'mega',
               'copy']

add 'rsync' to the list array and rerun your command.

does that work?.. ede

I had the same problem and the proposed fix of adding 'rsync' to the uses_netloc list works.
