Claims20
A method, comprising:
- logically linking a plurality of snapshots to a logical disk in a storage network;
- and
- splitting the snapshots from the logical disk to form a snapshot tree that includes the snapshots split from the logical disk.
A computer readable medium having instructions for causing a computer to execute a method, comprising:
- linking plural snapshots to a logical disk in a storage network, each snapshot including a copy of data at a different point in time;
- and
- splitting at least one snapshot from the logical disk to form a snapshot tree without deleting any of the plural snapshots.
A storage device system, comprising:
- a memory for storing logic instructions;
- and
- a processor for executing the logic instructions to:
- link plural snapshots to a logical disk in a storage network, each snapshot including a copy of data at a different point in time;
- and
- split snapshots from the logical disk to result in (1) the logical disk with no snapshots and (2) a snapshot tree with the plural snapshots.
