Image is a DOS based backup and restore utility that creates or restores a snapshot of an entire partition or volume.
Image for DOS can backup partitions and restore drives.
If something should ever happen to that partition or volume, you'll be able to simply restore the snapshot image.
The data can be backed up to or restored from just about any drive letter, including network drives, or the program can directly access FAT, FAT32, NTFS partitions as well as most USB2, IEEE1394, ATAPI or ASPI accessible CD-R/RW or DVD RW/ R/-R/-RW drives.
When saving to CDs or DVDs, they can be made bootable which provides you with a convenient recovery CD/DVD.
