Re: [Duplicity-talk] My Incremental and Full Scripts

[Timothee Besset]

While we're on the topic, I'll pimp my own wrapper too:

http://github.com/TTimo/dupinanny/

Pretty much same idea, automate incremental vs full, I set it up to run
from cron on various systems. Has support for breaking down a backup
into several smaller ones, failed backups have to be restarted
completely, since I do full machine backups on a slow link, I wasn't
able to get a single full backup through without breaking things down a bit.
