Abstract
A method and a system for preserving branch cache file data identifiers upon volume replication, the method including: calculating file data hashes associated with the file; storing the calculated file data hashes on a directory attached to the file; constructing file data identifiers for the file, based on the file data hashes and a secret server identifier of the first content server; providing file data of the file and the file data identifiers to the first branch cache client; caching the file data and the file data at the first branch cache client; replicating the file data hashes contained in the replicated volume; deriving the server secret identifier of the first content server; reconstructing the file data identifiers for the file, based on the replicated file data hashes and the derived server secret identifier of the first content server; providing the reconstructed file data identifiers to the branch cache clients.
