Hi,
I am using:
duplicity 0.6.23
python 2.7.3.-4
Debian weezy 2.6.32-5-amd64
I am having an issue with absolute path when backing up to FTP. It seems to me that duplicity ignores double slash before target path because it doesn't show in ncftp error message. I tried to override it with "%2F" and it started working and made full backup without problems but I have no luck with following backups which needs to download manifest from FTP to local filesystem. It allways ends with ncftp command without leading "/" in source address no matter what i enter as target URL. I guess there are two functions generating URL for ncftp which differs for ncftpget and ncftpput a bit but I am no programmer to figure it out. So I wanted to ask you for help.
Command:
duplicity full --no-encryption --full-if-older-than 7D /raid/documents ftp://backup@192.168.10.234/%2Fbackup/documents
Answer with verbosity 9:
Using archive dir: /root/.cache/duplicity/d36bbdbf56ef57733a75d81751cd79c4
Using backup name: d36bbdbf56ef57733a75d81751cd79c4

I have solved this issue, this is ncftp backend error. Will push update with fix.
