clink replaces duplicate files in Unix filesystems with symbolic links. It can achieve good space savings, for example on automatically-generated directory structures, such as compiling toolchains. It is fast; it reads each file only once, and its runtime is mainly the time taken to read files. It also consumes very little RAM and is very easy to use.
Paragon Drive Backup is a universal backup. It creates images of any partitions of the whole hard disk and places them on CD, DVD, or another partition or disk. It includes a bootable CD and an "undelete partition" function. It can be used to repartition, clone, or upgrade hard disk. It also includes Image Explorer, a tool to explore your backup images and restore only part of one of them. All versions of NTFS are supported, and fast processing is provided for FAT 16/32, NTFS, EXT2/3fs, and ReiserFs.
apachelogrotate.pl rotates and packs the logfiles of the Apache Web server on a Linux system without interrupting its service and without the need for a permanent change in the Web server configuration. Assuming that Apache is running, it will identify the log files which have to be rotated without any configuration, making it easy to install. By default, logfiles with more than 10 MB are rotated, but this parameter may be changed and/or a daily, monthly, or yearly rotation period can be configured. Documentation is included in the script itself.
