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).
This is the "progress" utility from NetBSD, ported to Linux and Solaris. The progress utility allows the file I/O of progresses to be monitored. It includes support for gzip-compressed files, so "progress -z -f file.tar.gz tar xf -" would show the progress of extracting file.tar.gz.
rsyncbackup is a handy tool for scheduled backups using rsync. rsyncbackup lets you easily setup multiple source folders and destinations, both locally, on your iPod or external firewire disk, or at a remote destination using ssh. rsyncbackup has no GUI, but is based on editing configuration files. The script is meant to be run in a crontab, so user interaction is not neccesary. Basic terminal skills are required to use the program.
Simplebackup is a cross-platform backup program. It reads a configuration file, then it builds a compressed file for each of your backup directories or files on your backup list, and places the compressed files into another location. For example, this location can be a network mapped drive in Windows, an NFS mounted drive in Unix, another hard disk, an FTP server, an SFTP (Secure FTP) server, an HTTP (WebDAV) server, one or more email accounts, or a tape device (Unix only). This will duplicate your information, doing the so called "backup".
bdmn is client/server-oriented backup system. The daemon runs on the machine being backed up, and the client runs on the machine that stores the backup. It is very simple, but very fast. It only uses tar, gzip, uuencode, and Perl, so it is portable to many operating systems. It includes a very simple access control system for itself.
Virus Update Server (vsuserver) helps you maintain an updated mirror of the antivirus updates from the McAfee/Network Associates servers without having to download the entire list of updates every time a new antivirus update is available. It mirrors all the files needed for serveral OSes, and it also includes a FAQ on how to configure clients to update for their version of the product.
Bacula is a set of programs that allow you to manage the backup, recovery, and verification of computer data across a network of different computers. It is based on a client/server architecture and is efficient and relatively easy to use, while offering many advanced storage management features that make it easy to find and recover lost or damaged files.
