Hot Copy creates an instant point-in-time snapshot of any block device while the system is running without interrupting applications or requiring the use of LVM. As block level changes are made to the real device, hot copy makes a backup copy of the changed block. The changed blocks are efficiently stored in unused space on your hard disk. These stored changed blocks maintain a point-in-time snapshot and space is only needed when you make changes to the real device. You can even write to your snapshots.
ISO Master is an easy to use GUI CD image editor for Linux, BSD, and Windows. Basically, you can use this program to extract files from an ISO, add files to an ISO, and create bootable ISOs, all in a graphical user interface. It can open both ISO and NRG files, but can only save as ISO. It is based on bkisofs, a library for reading, modifying, and writing ISO images.
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.
K9Copy facilitates several methods for backing up a DVD. The software enables direct backup of a single layer DVD-5, provided the user's computer has a DVD recorder. Likewise, direct backup of a dual layer DVD-9 is possible with a dual layer DVD recorder. K9Copy is also able to fit the contents of a dual layer DVD-9 onto a single layer DVD-5. The interface allows a user to explicitly retain or discard any content from the original disc such as video titles, audio tracks, subtitles, and the DVD menu. All content selected for backup is compressed to a configurable target size (4400 MB by default) and stored on the user's hard drive as either an ISO image file or a DVD VIDEO_TS folder. K9Copy can either transfer the backup data to blank DVD±R media or utilize external DVD authoring software such as K3b for this task. Furthermore, an ISO image file produced by K9Copy can be recorded to DVD by any software on any platform capable of recording ISO images to disc. It can also back up a DVD to a video file (such as MPEG-4).
