Abstract

Initially, a configuration script is stored either remotely or locally on a system. The configuration script is executed based on a set of predefined execution parameters, such as time based parameters, system usage or loading parameters, or even based on the types of operations being performed on the system. Once executed, the configuration script outputs a series of current configuration parameters to a safe storage area. These current configuration parameters define the system in terms of system hardware specifics, software specifics, and firmware specifics, including mappings from logical to physical disk drives. By recording such detailed information in a methodical form and preserving it in an accessible state, a script may be written to place every logical volume, every file system, and every block of data back onto its disk of origin, even if the disk arrays stretch into terabytes. By detailing all relevant system parameters, output can be fed as input into a reconstruction script, which can then be written by anyone skilled in UNIX administration, provided the administrator has the comprehensive system environment description generated by the present invention.
