Re: [Duplicity-talk] backing up using SFTP to a directory under my home directory

Luis,

aside from the possibility that your backend might be changerooted there is an 
official way to define an absolute vs. relative backend folder, which is 
described in the man page, section URL Format.

"
    scheme://[user[:address@hidden:port]/[/]path
...
In protocols that support it, the path may be preceded by a single slash, 
’/path’, to represent a relative path to the target home directory, or preceded 
by a double slash, ’//path’, to represent an absolute filesystem path. 
"

any specific reason that you use pexpect+sftp:// instead of default paramiko?
