Abstract:
1. A backup and reversion system for an information system, comprising: at least one host system for processing information; at least two storage systems, wherein only one of said at least two storage systems at a time may be communicatively connected to said at least one host system for processing information; at least one duplicator, wherein said at least one duplicator reads at least a portion of information from a source storage system of said at least two storage systems and writes said at least a portion of information to at least one destination storage system of said at least two storage systems; at least two switching systems, wherein said at least two switching systems function to switch all connections between each of said at least one host system and said at least two storage systems; and at least one controller system, wherein said at least one controller system communicates with and controls the functionality of said at least one duplicator and said at least two switching systems; wherein during duplication of said at least a portion of information from said source storage system to said at least one destination storage system, said at least two switching systems disconnect said at least one host system from both said source storage system and said at least one destination storage system wherein said at least one duplicator, said at least two switching systems, and said at least one controller system are transparent to said at least one host system and said at least two storage systems, whereby said at least one host system and said at least two storage systems are unaware that said at least one duplicator, said at least two switching systems, and said at least one controller system have been inserted therebetween, wherein said at least one duplicator, said at least two switching systems, and said at least one controller system are operating system independent from said at least one host system, wherein said at least one duplicator, said at least two switching systems, and said at least one controller system are immune to malicious code affecting said at least one host system.
