Shasplit takes a large data block, splits it into smaller parts, and puts those parts into an SHA-based content-addressed store. Reassembling those parts is a trivial "cat" invocation. Repeating parts (e.g., from previous split operations) are stored only once, which allows efficient incremental backups of whole LVM snapshots via Rsync. Shasplit shows its strengths on encrypted block devices, but might be useful for non-encrypted data, too.
SnaRSShE (Snapshots via Rsync in a Simple Shell Environment) is a simple, lightweight (both in size and system requirements) server data archiving package designed for secure and reliable archiving of critical data of defined network systems. The general idea was taken from the need to capture snapshots of data on a regular basis and have easy access to that data. Originally, the script handled alerting as well, but the author since recognized the sense in offloading the alerting to a separate system. This script is a front-end for rsync, which does the real work. SnaRSShE just creates the environment and manages the rotation of archives.
