The Vault is a collaborative document management system. It offers a central storage area for group documents, uses secure access to ensure that only users with appropriate permissions view or edit stored documents, makes it possible to identify which users were working on which documents at any point in time, tracks the changes made to each document, offers a quick and easy way to locate documents in a large repository and categorize them according to type, and provides a framework for multiple users to collaborate on a document, without imposing any special software requirements or constraints on them.
backupIT is a script to backup local and remote filesystems onto a remote tape drive. It includes a collection of functions to send mail, to use system commands to drive a tape library, and to use NetBackup(tm) to drive a tape library. backupIT uses rsh/ssh to connect to remote hosts, and it supports ufs, vxfs, and ext2 file systems. It works on Solaris, Slackware Linux, and Red Hat Linux systems. backupIT requires the dump utility, which might not be installed on Linux systems.
dnbackup is yet another client-server backup solution. Design goals include portability (within Unix variants), security, minimizing trust between client and server, ability to optimize for remote backups over slower speed links, and OS independence in the communication protocol (thus allowing for non-UNIX clients).
