ImageBackup is a fully automatic incremental backup system for digital pictures. It will create backup CDs, one at a time, until all images have been backed up. You than then run the program regularly and it will keep gathering images until another disc is full. Once a disc is full, it can use AutoScrapbook to create Web-based index files, automatically generate an ISO image, and reset the staging area. Once an image has been stored in a backup ISO image, it will not be backed up again. Any new images, regardless of where they are mixed into your directory structure, will be added to backups when necessary.
check is a simple commandline utility to calculate CRC-32 or Adler-32 checksums on the fly (that is, as a filter within a command pipeline), or to calculate such checksums on a list of files given as arguments. It is fast and was designed to be used for verification of backups and archives written to semi-reliable media (e.g., tapes), but it can also be used to compare files against versions stored within ZIP archives (same CRC) or to verify one-to-many copies without the need for multiple byte-for-byte comparisons.
FauBackup uses a filesystem on a hard drive for incremental and full backups. All backups can easily be accessed by standard filesystem tools. Later backups to the same filesystem will automatically be incremental, as unchanged files are only hard-linked with the existing version of the file.
imapsync is a tool for facilitating incremental recursive IMAP transfers from one mailbox to another. It is useful for mailbox migration or backup, and reduces the amount of data transferred by only copying messages that are not present on both servers. Read, unread, and deleted flags are preserved, and the process can be stopped and resumed. The original messages can optionally be deleted after a successful transfer.
snapshot is a set of Perl scripts for creating, accessing, and managing a repository of directory snapshots. Multiple snapshots of a directory can exist in a repository representing the state of that directory at different times. A snapshot repository can be local or remote, with remote servers accessed using SSH.
The Linbox Rescue Server (LRS) is a tool to centralize hard disk images (like Ghost Enterprise Server), file backups, hardware and software inventory (with Windows, Linux, and Mac OS X agents), secure software deployment using OpenSSH, and remote access on a single server. It can be managed from any PC through a Web-based administration interface, and disk images can be restored using PXE boot or using a bootable CD or DVD. It supports Ext2/3, ReiserFS, XFS, JFS, and LVM v1/v2.
Better Backup is a backup manager designed to handle large volumes of data at high speed. It is extremely fast and flexible. The system is designed to back up to magnetic tape, CD/R, or DVD-R, or almost any other media. One of the main features of this program is its ability to preform a fast restore from magnetic tape through its use of file markers. The program is extremely flexible allowing the user to customize most aspects of the backup through a configuration file.
