ShadowBack requires Windows 2000 (service pack 3 or higher) or Windows XP.

A Pentium class or higher machine is required for tape or hard drive backup, and a Pentium II running at 300MHz or higher is required for CDR or DVDR backups.

128 megabytes of memory is recommended, as well as 10 free megabytes hard drive space for the program and temporary files.

If you are backing up to CDR, you’ll need at least 100 megabytes of free space.

If you are backing up to DVDR, you’ll need at least 1 gigabyte of free space.
