Abstract

A data archiving method includes: finding, in local space when an archiving task for a target block header exists, current state trees of block headers, the current state trees including a current state tree that the target block header points to and a current state tree that a first block header before the target block header points to; reconstructing new state trees according to the found current state trees, node reuse information between the current state trees, and target state data corresponding to a second block header after the target block header; and archiving the current state trees stored in the local space to a target archiving server, and deleting the current state trees in the local space after successful archiving.
