CopyCatX is a backup software product produced by SubRosaSoft.com Inc. The software uses byte and block-level copying to make exact duplicates of devices and volumes.
Byte and block-level copying offer speed advantages over traditional file-copying used by most duplication and backup software. It also maintains every detail of the duplicated device such as icon placement, file permissions, and hidden files that file-copying often misses.
CopyCatX is device and file system independent. This means it can create duplicate and create disk images of any media that the Mac OS X system bus can recognize. Examples include; HFS+, NTFS, FAT32, and Ext2/ Ext3.
CopyCatX is offered on a bootable Mac OS X CD-ROM. This CD-ROM is a LiveCD. This allows the user to start their system using the CD-ROM and backup their system drive.
