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.

摘要： A method for data storage includes accepting write commands belonging to a storage operation invoked by a host computer, and caching the write commands in a volatile memory that is powered by external electrical power. A current execution status of the storage operation is also cached in the volatile memory. Responsively to an interruption of the external electrical power during the storage operation, the cached write commands and the cached execution status are backed up in a non-volatile memory. Upon resumption of the external electrical power, the backed up execution status is recovered, so as to resume the interrupted storage operation.

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.
