Re: [rdiff-backup-users] permission denied error when making backups

[Duk]

Hi Welloki,

Thank you very much for your help! I finally managed to do it :) effectively
I was missing the "sudo rdiff-backup ...." statement in the
ssh/authorized_keys now everything goes fantastic.

As well I found a tutorial it helped me to clarify me a bit more, I leave
the link here in case someone needs it:

Thanks again Weloki, happy backup :)
