Description: Duplicati is a free backup client that securely stores encrypted, incremental, compressed backups on cloud storage services and remote file servers. It works with Amazon S3, Windows Live SkyDrive, Google Drive (Google Docs), Rackspace Cloud Files or WebDAV, SSH, FTP (and many more). Duplicati has built-in AES-256 encryption and backups can be signed using GNU Privacy Guard. A built-in scheduler makes sure that backups are always up-to-date. Last but not least, Duplicati provides various options and tweaks like filters, deletion rules, transfer and bandwidth options to run backups for specific purposes.

My opinion: Duplicati can be run on CLI for those who like running batch file scripts. I got this from www.portablefreeware.com so I think this can be "portabilized". I hope this gets approved so that I dont have to worry about manually updating it.

When I needed to find a backup client for my Office 365, I went with this Office 365 backup solution from https://spinbackup.com/products/office-365-backup/. I believe that I've made the right decision.
