Method and system for instantly creating an IT environment

A method to provide instant duplication of the machine images of an IT environment from a source logical disk to at least one target logical disk, implemented by a system comprising:

• a management server to oversee all operations;
• a storage controller;
• at least one host target machine of the IT Environment;
• and at least two storage disks controlled by said storage controller, wherein said method comprises:
• configuring each host target machine to access a logical drive as its hard drive;
• receiving a request for duplicating said source disk from said management server;
• accessing said logical drive;
• managing by said storage controller of the information inside each said logical drive, and storing the information on each of said at least one target logical disks;
• implementing by said storage controller of at least one of a first and a second duplication algorithm, wherein:
• said first duplication algorithm is suited for duplication of an area in said at least one target disk undergoing a plurality of changes over time relative to said second duplication algorithm providing a file system structure with many more read operations than write operations;
• wherein if both of said first and second duplication algorithms are implemented, said implementing step includes implementing a selection algorithm for choosing between said first and said second duplication algorithms for each element of said at least one target disk in the IT environment.
