[Duplicity-talk] duplicity - verify if backup needed

[eleanor]

Hi.

I would like to know if there's a way with duplicity to check if
backup is required - that is to check if there are any
modified/deleted/added files in the chosen directory.

The command that I'm using now is:

# duplicity --dry-run --ssh-options /home/testing
scp://address@hidden/backup/testing
GnuPG passphrase:
Local and Remote metadata are synchronized, no sync needed.
Last full backup date: Thu Dec  8 15:03:51 2011

-------------------------------------------------

In this output se can see that the files have not been
added/modified/deleted - which is probably written in the local
indexing file - used by duplicity.

The problem with this is that the local directory has 310MB of data
and the data is not synchronized. How can I check whether the data is
actually in sync or not.
