Abstract
Preparing source data to be replicated in a continuous data replication environment. Certain systems and methods populate a file name database with entries having a unique file identifier descriptor (FID), short name and a FID of the parent directory of each directory or file on a source storage device. Such information is advantageously gathered during scanning of a live file system without requiring a snapshot of the source storage device. The database can be further used to generate absolute file names associated with data operations to be replayed on a destination storage device. Based on the obtained FIDs, certain embodiments can further combine write operations to be replayed on the destination storage device and/or avoid replicating temporary files to the destination system.
