Hello Everyone
I faced a problem about alfresco backup for a long time,I have done that follow the link https://addons.alfresco.com/addons/alfresco-bart-backup-and-recovery-tool,but when I run "duplicity" and ./alfresco-bart.sh backup,it's appear some error:
Traceback (most recent call last):
  File "/opt/duplicity/bin/duplicity", line 45, in <module>
    from duplicity import collections
  File "/opt/duplicity/duplicity/collections.py", line 29, in <module>
    from duplicity import path
  File "/opt/duplicity/duplicity/path.py", line 36, in <module>
    from duplicity import librsync
  File "/opt/duplicity/duplicity/librsync.py", line 29, in <module>
    import _librsync
ImportError: No module named _librsync,

Your question is nothing to do with alfresco.   Looks like python is missing a library.

Hi
This has nothing to do with alfresco, it is an addon created seperated. I created the script.
