node-duplicity (duplicity.js) 
Latest Release:
Alpha Hint: This is work in progress.
This small command line tool is a javascript powered cli wrapper for duplicity. It wraps the output of the python-based duplicity cli tool into javascript calls and returns json.
Since it's a npm module, it might be integrated into an existing nodejs application.
Installation
$ npm install duplicity -gCli Usage
Let's say, you want to backup a folder called myproject into a local backup at file://backup.
Create a file called .duplicity.json for your configuration (the passphrase will be used for encryption!):
{
"env": {
"PASSPHRASE": "hans"
}
}Backup myproject to the backup directory:
$ duplicity.js full-backup myproject file://backup
