multicd provides an easy way to backup a large number of files to multiple CDs or DVDs. Give multicd the files/directories you want backed up and it will create as many CDs or DVDs as it needs to, prompting the user to put in a new disc whenever needed. It can be configured to run in a multi-threading mode, where it will burn one image to a disc while it is copying files to another image. This feature can be disabled for slower machines.
NewSyslog is an updated version of a package put together by Theodore Tso of MIT Project Athena (which is included in NetBSD, FreeBSD, OpenBSD, etc.). It manages the rotation and archiving of log files (primarily those written to by syslogd). This version has a mix of features from all of the other versions, and it has been made more portable than any of the others with the help of GNU Autoconf.
nfsbu consists of two scripts written in Perl to help automate backing up data between two servers via an NFS mount. Its features include error reporting via e-mail, automatic NFS mount/unmount, error-checking to prevent NFS from causing a hang (as can be happen when the NFS server dies or doesn't respond), directories to back up can be listed in the configuration file, and either use the same or alternate destination directories on the backup server.
CD-R/W discs can be written with a technique called packet or incremental writing. This allows transparent and buffer-underrun-free recording for CD recorders that support this method. No more mastering of .iso images; just mount your CD-ROM read/write and copy files directly to it.
Payload Delivery Vehicle (PDV) is a program that builds an executable that contains a complete package (e.g. and RPM, System V package or tar file) and the commands required to install it. When the executable is run it will extract the payload (the package) and then execute another command (such as rpm -i, pkgadd -d etc.). The big advantage to this is that a developer can hand a user a single file to be executed - the end user does not need to know how to extract the package or get it installed.
Perl-LZO (aka Compress::LZO) provides Perl bindings for the LZO data compression library. You can access the LZO library from your Perl scripts thereby compressing ordinary Perl strings. LZO is a portable lossless data compression library written in ANSI C. It offers pretty fast compression and very fast decompression. Decompression requires no memory. In addition there are slower compression levels achieving a quite competitive compression ratio while still decompressing at this very high speed.
pkgusage lists all the packages you have installed on your system, along with a number telling you how many days ago you last accessed any of the files in the package. This could be useful for cleaning out your hard drive. Pkgusage works with RPMs and Debian packages, and is written to be easily portable to other package managers as well.
plbackitup is a simple Perl script for backing up directories/files to a tarball. It uses a flat file database for selecting what to backup, and features logging, excludes, email notification, FTP backup files, scp files, and removing old tarballs in the backup directory. It can be run as a cron job or manually.
