The dump package contains both dump and restore. Dump examines files in a filesystem, determines which ones need to be backed up, and copies those files to a specified disk, tape or other storage medium. The restore command performs the inverse function of dump; it can restore a full backup of a filesystem. Subsequent incremental backups can then be layered on top of the full backup. Single files and directory subtrees may also be restored from full or partial backups.
fistgen is the FiST language code generator, used to create stackable file systems out of templates and a high-level language. This package comes with stackable file system templates for Linux, Solaris, and FreeBSD. It also contains several sample file systems built using the FiST language: an encryption file system, a compression file system, and more - all of which are written as portable stackable file systems.
mkCDrec (Make CD-ROM Recovery) makes a bootable (El Torito) disaster recovery image, including backups of the Linux system to one or more CD-ROM(s) (multi-volume sets). Otherwise, the backups can be stored on another disk, NFS/CIFS disk, or (remote) tape. After a disk crash or system intrusion, the system can be booted from the CD-ROM and one can restore the complete system as it was. It also features disk cloning, which allows one to restore a disk to another disk (the destination disk does not have to be of the same size, as it calculates the partition layout itself). Currently, ext2, ext3, minix, MS-DOS, FAT, VFAT, Reiserfs, XFS, and JFS filesystems are supported. It can restore disks in Software RAID and LVM mode. It supports the One Button Disaster Recovery (OBDR) mode, which simulates a bootable CD-ROM on tape.
makeself is a small shell script that generates a self-extractable compressed TAR archive from a directory. The resulting file appears as a shell script, and can be launched as is. The archive will then uncompress itself to a temporary directory and an arbitrary command will be executed (for example, an installation script). This is pretty similar to archives generated with WinZip Self-Extractor in the Windows world.
RAR is a general purpose archiving and compression program competing with/replacing programs such as PKZip, ARJ and others. RAR offers significantly improved compression ratios, easier use and a better price as well as supporting long file names, disk spanning and self-extracting file creation. RAR introduces an original compression algorithm. It allows higher compression ratios than other PC archiving tools, especially on executable files, Object libraries, large text files, etc.
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.
CFL (Compressed File Library) is meant for the save-files used by games, and other sorts of data files. Its features include pluggable class factories, easy CFL file creation at runtime, and the ability to have multiple separate CFL objects in memory at the same time. The package also includes a CFL testing tool to make it easier to port the library and to create additional plug-in compressors, preprocessors, and ciphers. It also includes a makecfl utility, which makes it easy to create ini files.
