DATA MIGRATION

摘要

Data migration data may include analyzing data to be migrated from a first device to identify data blocks containing content that is the same at an abstraction layer and constructing a content map. Entries in the content map may respectively correspond to unique contents found at the abstraction layer, and each of the entries may include a list of addresses at which the unique content corresponding to the entry can be found. The unique contents may be sent from the first device to the second device and written in the second device at addresses selected based on the content map and using the abstraction layer in the second device.

1. A process for migrating data, comprising:
analyzing data to be migrated from a first device, to identify data blocks containing content that is the same at an abstraction layer; constricting a content map having a plurality of entries respectively corresponding to a plurality of unique contents found at the abstraction layer, wherein each of the entries includes a list of one or more addresses at which the unique content corresponding to the entry can be found in the first device; sending the unique contents from the first device to a second device; and writing the unique contents in the second device at addresses selected based on the content map and using the abstraction layer in the second device.
