[Duplicity-talk] Anyone using duplicity with box.net (webdavs)?

[Brian Wilson]

I'm trying to use duplicity with box.net (which has a WebDavS interface) but 
not having much luck.   Backups seem to run fine, but I'm unable to verify or 
do any restores.  I found similar mention of this in the issue list for 
duplicati (http://code.google.com/p/duplicati/issues/detail?id=217) and that it 
may be due to non-standard compliant WebDav server on box.net.   Since I'd like 
to make use of my 50GB free space, it would be great if this would work.  I've 
even tried disabling encryption to test but verify and restore still fail: 
Here's what I'm seeing:

This runs without issue:
/usr/local/bin/duplicity -v9 --tempdir=/data/tmp --full-if-older-than 14D 
--no-encryption --include=/home/user/bin --exclude=** / 
webdavs://address@hidden:address@hidden/dav/duplicity

I verify that files actually exist in the duplicity folder from the box.net web 
UI.

I then try to run verify and get this:

Any suggestions on working around the box.net WebDav issues in order to get 
proper file listings so duplicity knows that I have backups and thus allow me 
to do restores?  5GB accounts are free if anyone would be willing to help me 
figure this out.

Thanks!
