SnapSource is a utility written in Perl to automatically and periodically take a snapshot (incremental backup) of your source code and display the modifications in a 2-column (original and modified) format similar to that of cervisia. Changes, additions, and deletions are displayed in different colors, customizable per user preference. It is not another CVS, and it is not a front-end to CVS, but it is supposed to be used in between CVS commits.
httplog is a replacement for Apache's 'rotatelogs' and Andrew Ford's 'chronolog'. It allows you to specify a logfile using strftime paramaters in the filename to act as a template. This means that the logs in your logfiles will also be sorted according to the filename. For example, if you specify a logfile of /var/log/http%Y%m%d.log, a new log file would be generated each day, with content for only that one day. It also supports compression of logfiles using gzip, and many other useful functions.
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).
LazySync is a file-synchronization program written for handheld devices using the SavaJeXE Java operating system. It attempts to offer similar functionality to HotSync and ActiveSync of the Palm and CE platforms, and supports synchronization via an existing TCP/IP network connection between handheld and host.
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.
