mega and duplicity

I used duply.sh with duppicity and mega. When i run first full backup all working ok. But next backup incremental have a this error.

I can confirm this.

duplicity 0.7.01

mega.py==0.9.18

Also mega.py contains note:

Mega.py is now deprecated, please use the official SDK https://github.com/meganz/sdk2.

The backend should probably be rewritten to use the official SDK. Should we rename this bug, or write a new one which would then block this?

I've been trying duplicity for personal backups, and realized I have a Mega account that I'm not using. But I ran into exactly this issue :-(

The mega.py library is deprecated and thus unlikely to get fixed, and I didn't feel like writing a new client from scratch on top of the new Mega SDK. But there are existing clients/tools, like for example megatools (https://megatools.megous.com/), which seems to be well maintained and working.

After a bit of hacking (first time I looked into duplicity), I've been able to switch the Mega backend to megatools, and it seems to be working like a charm so far. I'm sure there are things to fix, but is calling command-line tools from the backend acceptable design? It's certainly better than the current broken backend, I guess.

How do I contribute to the project on launchpad.net? I'm not very familiar how that works on bzr/launchpad.

For now, just attach your megabackend.py to this bug report and that should be all we need.

See below for "Add attachment or patch" button.

Attached is the hackish version of Mega backend.

There are a few rough edges (e.g. _makedir_recursive should be more careful and _put should not print errors that the remote file does not exist).

I'm not sure what to do with the copyright notices at the beginning - as the backend is pretty much a new implementation unrelated to both gdocs and the old megabackend code, I suppose the old notices should be removed replaced with a new one.

Another thing I should probably point out is that the backend now falls back to .megarc if the credentials are not specified in the target directly. That was a bit of an experiment to get rid of the credentials from the command line (so that it's not visible in 'top' for example).

Tomas,

could you please check the manpage, especially section REQUIREMENTS

  http://duplicity.nongnu.org/duplicity.1.html

and send an updated version or just state what needs to be updated and where in the manpage?

Ken: you forgot the manpage adjustments again! ;)

thanks.. ede/duply.net

Will get a patch out soon.
