摘要： Various systems, processes, and products may be used to source clean cascaded volumes. In particular implementations, a system, process, and product may include the ability to store a number of cascaded backup volumes and prepare received writes for storage. The system, process, and product may also include the ability to examine a metadata set associated with a volume region for a write to determine whether another volume depends on the region and write the new data to the region if another volume is not dependent. The system, process, and product may further include the ability to determine whether a write is for a volume region that is a canonical source and, if so, decrement a reference count in a metadata set associated with the region and establish the volume of the region as a canonical source for a metadata set associated with a new metadata set location identifier.

摘要： Various systems, processes, and products may be used to manage remote data replication. In particular implementations, a system and process for managing remote data replication may include the ability to store versions of a disk at a first site, a second site, and a third site. The version of the disk at the first site may store input/output for a host system, the version at the second site may be a synchronous replication of the version at the first site, and the version at the third site may be an asynchronous replication of the version at the first site. The system and process may also include the ability to synchronize the version at the first site with the version at the third site if the second site is unavailable and synchronize the version at the second site with the version at the third site if the first site is unavailable.

摘要： Provided are a method, system, and a computer program product handling a backup process. An instruction is received initiating a new backup from a source volume to a target volume using one of a plurality of backup processes. A determination is made as to whether there is a cascade of volumes using the backup process including the source volume of the new backup. The cascade includes a cascade source volume and at least one cascade target volume, and a write to a storage location in one of the cascade volumes causes a copying of the storage location to be written in the cascade source volume to each of the cascade target volumes in the cascade according to a cascade order in which the at least one cascade target volume and the cascade source volume are linked in the cascade. The cascade, using the backup process of the new backup already including the source volume of the new backup, is modified to include the target volume of the new backup in response to determining that there is the existing cascade. A new cascade using the backup process of the new backup including the source volume and the target volume of the new backup is created in response to determining that there is not the existing cascade.

摘要： According to one aspect of the present disclosure, a system and technique for coordinating write sequences in a data storage system includes a processor configured to receive from a primary device, responsive to the primary device receiving a request to write to primary storage, a request for a sequence number. The system also includes a sequence generator configured to: generate a current sequence number for the write; generate a first identifier indicating an identity of secondary devices writing to secondary storage based on the current sequence number; generate a second identifier indicating an identity of secondary devices writing to secondary storage based on the current sequence number and a previous sequence number; transmit the current sequence number and the second identifier to the primary device; and transmit the current sequence number and the first identifier to the secondary devices writing to secondary storage based on the previous sequence number.
