ESR Backup

ESR Backup (Easy, Secure, Remote) is a backup system for UNIX and Linux that is easy to use and configure. It automatically performs full and incremental backups on files you choose, and automatically rotates and archives your backups, encrypts archives with a 448 bit key, and can store archives on a remote server via FTP or on the local file system.

    Release Notes: The ability to perform differential backups has been added. Support has been added for setting a backup schedule within the configuration file. This will allow you to set the type of backup that is performed on each day of the week. In past versions, this was hard coded. The ability to specify the date the backups are rotated has been added; in past versions, this was hard coded to be Sunday. Many bugfixes and code enhancements were made.

Adds better support for upgrades.
