Information on using Duplicity  dpbackup script
===============================
http://duplicity.nongnu.org/


Summary
---------------

Duplicity has been around since 2002,  I'm testing with v0.5.14, v0.6.16
Duplicity is similar to rdiff-backup, however instead of creating a mirror of files
on the remote device, duplicity compresses ( and optionally encrypts ) them.
We are NOT using encryption for backups.

Duplicity in it's simplest form is run like this.

    duplicity       /source_dir      scp://host.net/target_dir

However, logging and emailing results need to be handled in a wrapper script.



Wrapper
--------------

Several wrapper scripts are available on the duplicity site,  for using duplicity with Amazon S3
and local storage.

Since none of the scripts were ideal,  I've taken the best feature and written dpbackup.
Available here:   ftp://4aero.com/pub/dpbackup/

Use
-----
dpbackup is edited for your desired source directory and storage location

Call dpbackup like this:

dpbackup                     - incremental backup
dpbackup full                - Full backup
dpbackup stats               - Show statistics of all backups.
dpbackup restore dir         - Restore 'dir' inside backup location NO LEADing or TRAILing slashes !
			       enclose in single ' parenthesis for embedded spaces.
dpbackup --help              - print use summary

Logs
-------

Logs are stored ,  normally in /home/user/logs/,   Separate logs for Full and Incremental.
Logs for the same day are concatenated together.

Email
----------

The logfile for the day is emailed after each backup to the designated user.
