摘要: Described are techniques for performing restoration processing for a data segment. A list of tokens is received. The list represents a first data state of said data segment. Each of the tokens correspond to a data portion of said data segment. Data portions of the data segment are scanned. A token is determined for each data portion. The token represents the data currently stored in said data segment at said each data portion. For each data portion of said data segment, it is determined whether a first token from said list associated with said each data portion is different from a second token associated with said each data portion. The second token is determined as part of said scanning and corresponds to data currently stored at said each data portion. Each data portion of the data segment determined to have a first token that is different from a second token representing data currently stored at said each data portion is restored.

摘要: Described are techniques for representing a data segment comprising. A list of one or more tokens representing one or more data portions included in the data segment is received. A unique identifier uniquely identifying said data segment from other data segments is received. A signature value determined in accordance with said list of tokens and said unique identifier is received. The list of tokens, said unique identifier, and said signature value are stored as information corresponding to said data segment.
