Chiron FS is a FUSE based filesystem that implements replication at the filesystem level like RAID 1 does at the device level. The replicated filesystem may be of any kind you want; the only requisite is that you mount it. There is no need for special configuration files; the setup is as simple as one mount command (or one line in fstab).
The WebReboot Plugin for Nagios is a suite of commands that can be used within Nagios to monitor a server and take corrective action if necessary via the WebReboot line of products. For example, the plugin can be used to alert you if a host is powered down, versus simply not responding to network requests. Likewise, it can be used to reboot a server if a host fails to respond to ping, or to shut down a server when a critical temperature threshold is exceeded. The commands can be mixed-and-matched with all existing Nagios commands, maximizing total network coverage.
The GNU Tar Autoloader Patch allows you to automate tape loading (during writing) on any autoloader that supports changing to the next tape with the "mt offline" command. This only has an effect during backup. During restore, you will still have to manually change the tape because tar hops back and forth various times. It behaves exactly as upstream except during a write operation (using the "c" flag) with multiple tapes (using the "M" flag).
DIASER is a cloud storage class combined geo-data replication, long-term archive system, and WAN vault application. Manage long term mixed data archives generated by existing backup software. Ensure availability using commodity hardware. Retain administrative and financial control. It combines a disk-based backup volume management system and triple redundancy with a storage architecture designed to structure months to years of long term sustainable archiving space. It is a quick and low-cost way to make an environment more robust by backing up data in multiple places. This replication also provides fast retrieval of archived data from all node hosting locations. A Perl installer creates the system. Nodes can be dedicated to storage or used for existing services over unused bandwidth. DIASER works in user space over SSH.
iloog is a Gentoo-based live CD targeted mainly at students and scientists. It features UnionFS filesystem support that enables you to write everywhere on the LiveCD and install extra packages, a graphical X environment through the Fluxbox window manager, many programming editors and IDEs, and a plethora of scientific applications, including Octave, Namd, Merlin, and full (La)TeX support.
pbackup is a small utility for backing up and restoring file permissions on GNU/Linux and compatible Unix-based systems. It enables you to store the current access permissions from any part of the file system to a local file. This file can later be used to restore modified access permissions if needed.
BG-Tiny Linux Bootdisk is a Linux bootdisk that does not use a ramdisk, so it will run on computers with very little RAM. It is basically a somewhat extended fork of Tiny Linux Bootdisk. It is based on Linux 2.4 series, uClibc, and BusyBox. It includes dosfsprogs, e2fsprogs, gpart, lilo, and ms-sys. Supported filesystems are ext2, ext3, iso9660, tmpfs, and vfat.
