Abstract
A data migration method and system is provided. The system includes a central control node, a first shard storage space associated with a first agent node, a second shard storage space associated with a second agent node, and a data backup subsystem. The data backup subsystem stores chunks of the first shard storage space and chunks of the second shard storage space. The central control node sends a data migration command to the first agent node. The first agent node obtains a to-be-migrated first chunk by using the data backup subsystem. The first agent node sends the to-be-migrated first chunk to the second agent node. The second agent node imports the to-be-migrated first chunk into the second shard storage space.
