    摘要: A method, including defining a snapshot referencing a source partition of a storage volume on a storage device, and receiving a request to write a block of data to the source partition. Upon receiving the write request, a delayed instant copy operation is initiated by allocating a target partition on the storage device and replacing, in the storage volume, the source partition with the target partition. A definition of a condition for completion of the delayed instant copy operation is received, and the delayed instant copy operation is completed upon the condition being met.

    摘要: In a local storage system having a local volume with a plurality of local regions, respective local signatures are computed over the local regions. In a remote storage system having a remote volume with remote regions in a one-to-one correspondence with the local regions, respective remote signatures are computed over the remote regions. A given remote region is identified, the given remote region having a given remote signature and a corresponding local region with a given local signature that does not match the given remote signature. The data in the given remote region is then replaced with data from the corresponding local region.
