Re: [Duplicity-talk] ReadError: unexpected end of data

[Jansen, Willem]

Dear all,

now same here as well - see attached (18MB logfile).

Any idea hwo to cure this? It is against a full backup of >300GB, and I've redone the full backup already once ...

Hi,

I've been using duplicty (0.6.something and now 0.7.07.1 with python 2.7.12) via duply.
After one full and several incremental backups, all successful, it suddenly stopped working with a "ReadError: unexpected end of data".
I now get this error every time.

The end of a run with verbosity=9 looks like:
---------------------------------------------------------------------------------------------------

ReadError: unexpected end of data

What does this actually mean? What could I try to fix the problem or at least figure out what is wrong?


Best regards,
