Introduction

RCB (Rsync-Crypto-Backup) is a set of scripts in Bash that:

• Create local backup with rsnapshot
• Encrypt local backup with rsyncrypto
• Sync encrypted backup to the remote server with rsync
• Restore the backup and
• Compare the restored data with the origin

Rsyncrypto ensures that doing rsync to synchronize the encrypted files to another machine will have only a small impact on rsync’s efficiency. Whole RCB project is approximately 500 lines long.

Installation and configuration was tested with Ansible role https://galaxy.ansible.com/vbotka/rcb/ with FreeBSD and Ubuntu.
