Pstdelta can be used to store the differences between an old and new version of an Outlook .pst file. It can then generate the new file using just the old file and the output generated by pstdelta. It was created in order to vastly reduce the size of differential backups of .pst files.

K9Copy facilitates several methods for backing up a DVD. The software enables direct backup of a single layer DVD-5, provided the user's computer has a DVD recorder. Likewise, direct backup of a dual layer DVD-9 is possible with a dual layer DVD recorder. K9Copy is also able to fit the contents of a dual layer DVD-9 onto a single layer DVD-5. The interface allows a user to explicitly retain or discard any content from the original disc such as video titles, audio tracks, subtitles, and the DVD menu. All content selected for backup is compressed to a configurable target size (4400 MB by default) and stored on the user's hard drive as either an ISO image file or a DVD VIDEO_TS folder. K9Copy can either transfer the backup data to blank DVD±R media or utilize external DVD authoring software such as K3b for this task. Furthermore, an ISO image file produced by K9Copy can be recorded to DVD by any software on any platform capable of recording ISO images to disc. It can also back up a DVD to a video file (such as MPEG-4).
Arkeia Network Backup Enterprise Edition for Ubuntu LTS is a completely free version of the Arkeia Network Backup software specifically for Ubuntu servers. It is available in the Ubuntu LTS (Long-Term Support) software repository. It allows an administrator to backup and restore files via a Web UI. This edition has the option to backup up to 2 machines to a 250 GB VTL or tape drive. It allows you to backup Linux machines, Windows desktops, Mac desktops, FreeBSD servers, and more.
Dconf is a tool to collect a system's hardware and software configuration. It allows you to take your system configuration with you and compare systems (like nodes in a cluster) to troubleshoot hardware or software problems. It can also be configured to send out configuration changes at given intervals to a group of people, or store a new snapshot when system changes happen.
histbackup makes incremental backups of a directory tree in a set of directories named by dates, or date-time if the date already exists. Its companion script histbackup-prune controls the archive growth. The new backup is prepopulated by hardlinks of each file from the previous backup and then updated with rsync(1). This arranges that the only new content of each new backup is fresh copies of the changed files. In this way each backup directory is a full copy of the source directory but the disk space cost is that of an incremental backup. Because it uses rsync, it is possible to efficiently backup remote directories in this manner.
zfec is a fast, portable, and programmable implementation of erasure coding. It includes a C library, a Python library, and a command-line tool. Erasure coding is also known as "forward error correction", which is the generation of redundant blocks of information such that if some blocks are lost then the original data can be recovered from the remaining blocks. The RAID-5 algorithm is an erasure code, but while RAID-5 can recover from the loss of any one element, zfec can be parameterized to choose in advance the number of elements whose loss it can tolerate.
digup is a console tool to update md5sum or shasum digest files. It will read existing digest files, check the current directory for new, updated, modified, renamed, or deleted files, and query the user with a summary of changes. After reviewing the updates, they can be written back to the digest file. This makes digup very useful to update and verify incremental archives like chronological data storages, which are commonly stored and backed up on hard disks. Using a full file digest scan, even slowly creeping bad blocks on old hard disks can be detected. By using a crontab entry, this check can be performed unattended and routinely.
