JBup (Java Backup) aims to become a robust, professional backup tool. It creates a mirror of the current file set and compares it to the previous version. The deltas are saved and the previous mirror is removed. By applying the increments in reverse time order, complete backups of arbitrary versions can be created. It is an Ant task and can therefore be used in Ant scripts that perform additional backup actions, such as archiving directories or sending emails.
