Duplicity

sftp failed error

Asked by Gabriele Tozzi

Hello,

I'm trying to use duplicity for the first time. I've correctly setup and verified ssh shared key authentication.

When i try to backup, I get this error. Duplicity creates some files on the remote site of approx size of 160/320K then fails.

May someone help me?

Hi,

yes, this is the first (full) backup I'm trying.

duplicity 0.6.08b

I guess a former incomplete backup can't be resumed...
or
a connection issue to storage2.datastorageunit.com

can you
ssh storage2.datastorageunit.com ?

did you try to manually delete the incomplete backup and run a new full backup?
duplicity full <parameters ...>

yes, ssh connection is ok and stable.

Running a new full backup gives me the same issue.

I had the same problem, because the locale of the system wasn't available on the backup server.

Can you help with this problem?
