Abstract
Incremental checkpoint, for use in data replication, track the changes made to a file system after a point in time at which the incremental checkpoint is created. Data replication techniques using the incremental checkpoints may include taking a regular checkpoint of the file system and creating the first time full copy on remote node using the regular checkpoint. Changes made to the file system are then tracked in an incremental checkpoint that are stored on the remote node. The processes of taking the incremental checkpoint and storing the incremental checkpoint are iteratively performed. The first time fully copy and the incremental checkpoints may then be used for data replication, backup, continuous data protection (CDP), or the like.
