Re: [Duplicity-talk] Re: Strange Error Message?

Hi Ben,

sorry for the delay, I was busy the last weeks.

The problem was definately the too long user-id's Apache/PHP was creating. 
After changing their config to avoid this, duplicity works without any errors 
so far. Thanks for this great tool!

But I don't understand your question "what tar does to your file". So if it is 
still of interest for you, perhaps you could clear things up a bit.

Ciao,

Doc SoLo
