rsync-mirror is used to backup local directories to another location on the local machine or to a remote machine. As the name suggests, it uses rsync for data transfer so it should be pretty efficient. It does not support any nifty backup features like incremental backups; all it does is mirror a directory to another location. To ease the task of creating backups, rsync-mirror takes care of managing the destination site of the backup. In case the target path needs to be mounted, rsync-mirror does so before backup and unmounts it afterwards.
Poplog is a high-level programming environment including the languages: Pop-11, ML, Common LISP (including CLOS), and Prolog. Poplog allows the programmer to write mixed-language programs and perform incremental compilation. It includes a fully customisable text editor (VED) with multi-font capabilities, a comprehensive X interface including Athena, Motif, and OLIT widget set support, a custom Poplog widget set including a neat text-editing widget, and an easy to use graphics widget. It supports graphics elements such as graph drawing, turtle graphics, high-level support for creating dialog-box based applications, and a multi-window X based implementation of VED (XVed). Poplog implementations are available for Solaris and Intel Linux, AIX on PPC, Digital Unix Alpha and Windows9X/NT.
Magic Mirror Backup works by copying the files and folders on your computer to other computers within your office. In exchange, these other computers also copy their own files onto your computer. This sharing of backups has quite a few advantages not the least of which are that it is extremely convenient and cost effective. (This symbiotic mechanism for backing up data is often called peer to peer backup or p2p backup.) There is also an optional off-site component so that you can additionally backup to a remote server to protect against office-wide failures like fire, theft, or hurricanes.
