VOLUME INITIALIZATION FOR ASYNCHRONOUS MIRRORING

摘要

Methods, apparatus and computer program products implement embodiments of the present invention that include conveying first data from local regions of a local volume of a local storage system to a remote storage system having a remote volume with remote regions in a one-to-one correspondence with the local regions. While conveying the first data, a request is received to update a given local region, and the given local region is marked. Subsequent to conveying the first data, a local snapshot referencing the local regions is created, and second data is conveyed from the marked local region to the remote storage system.
