Abstract:
A system and method are presented that reduce the use of snapshot space. One embodiment of the present invention only performs snapshot copies for blocks on the source volume that have not yet been backed up. Another embodiment stores the data in the snapshot space in multiple files, and then deletes those files that contain data whose corresponding blocks have been backed up. A third embodiment stores the data in the snapshot space directly onto a dedicated device and then reuses the data blocks for data already backed up when the dedicated device is full.

Claim (Index 9):
The method of  claim 1 , wherein the snapshot space is maintained on a dedicated device, and further comprising the steps of:\n h) copying a plurality of source data blocks on the source volume to the snapshot space, wherein the snapshot space maintains an association between a source volume offset of the copied source data blocks and a snapshot offset where the data blocks are copied; i) when the snapshot space is full and additional source data is to be copied to the snapshot space, performing the following sub-steps:\n i) identifying a first snapshot offset location of copied data that has already been backed up by the block-level backup, and \n ii) copying the additional source data to the snapshot space at the first snapshot offset location.
