Patent ID: 6850945

Claim:
A method of generating a frozen image of a system having a plurality of logical storage objects, including a first logical storage object, wherein the first logical storage object includes a storage device, the method comprising: building a logical storage tree with the first logical storage object as the root object and with the storage device as a leaf node; starting at the leaf node, constructing a freeze list for freezing the first logical storage object, wherein the freeze list includes one or more freeze methods, and wherein a given freeze methods includes operations configured to generate a frozen image of the leaf node according to storage device split and quiesce characteristics; modifying the freeze list as a function of traversing the logical storage tree to the root object, wherein modifying includes adding information about split and quiesce characteristics for logical storage objects between the root object and the leaf node; selecting a freeze method from the freeze list; and freezing the first logical storage object using the selected freeze method.
