Double Image-O provides power users added features to copy dynamic disk, like all types of RAID configurations. Double Image-O is point-in-time snapshot backup software that has the ability to copy any or all folders on local drives, including any 'in-use' files and relational databases.
Most high-profile backup applications use proprietary file formats for saving either one large drive image or a series of compressed packages. The primary strength of Double Image-O is its universality. After copying a 57GB partition in just over 67 minutes, all of the data on the target looks just as it did on the source. In comparison, Dantz Retrospect, Norton Ghost, and Drive Image 7 all use packaging systems that aren't readily accessible by Windows Explorer. The downside is that by default, Double Image-O doesn't use any sort of compression and takes awhile to execute a complete backup. Incremental backups are much quicker, fortunately.
Double Image-O is unique in its ability to back up and restore Linux and Novell clients connected over a network. It isn't limited by client licenses either, as Double Image-O can back up multiple clients across local and remote networks. According to Bryant Kittelson at Host Interface, Mac support is also on the way. Support for open-file backup is another instrumental feature, as is scheduling.
