摘要： Provided are a computer program product, system, and method for using geographical location information to provision one or more target storages for a source device. A determination is made of a geographical location of the source device and of geographical locations of the target storages. A determination is made of one of the target storages whose distance from the source device based on the geographical locations of the source device and the target storages satisfies at least one distance requirement. A configuration procedure is initiated to configure the source device and the determined target storage to have the source data backed-up from the source device to the target storage over the network.

摘要： For restoring deduplicated data, a method maintains a chunk index on a client computing system coupled to a client data store. The chunk index tracks chunks within files remaining on the client data store after storage of the files to a deduplicated server data store coupled to a server computing system. The method determines whether a valid entry for a first chunk exists in the chunk index. In addition, the method retrieves the first chunk from the server data store responsive to determining the valid entry for the first chunk does not exist in the chunk index. The method further retrieves the first chunk from the client data store specified in the valid entry of the chunk index responsive to determining that the valid entry exists in the chunk index and the first chunk resides in a first file at a first offset.

摘要： Provided are a computer program product, system, and method for using geographical location information to provision multiple target storages for a source device. A determination is made of a geographical location of the source device and a distance between the source device and each of the target storages and between each pair of target storages. A determination is further made of qualifying k-tuples of the target storages, wherein each k-tuple comprises a group of k target storages to which the source data is to be backed-up. A qualifying k-tuple has one target storage that satisfies a distance requirement with respect to the source device and a distance between any two target storages in the k-tuple satisfies the distance requirement. A selected qualifying k-tuple is indicated to use to backup the source data at the k target storages in the qualifying k-tuple.

摘要： Provided are a computer program product, system, and method for replication of versions of an object from a source storage to a target storage. A source retention policy indicates at least one source retention requirement to determine when to expire versions of an object at the source storage and a target retention policy indicates at least one target retention requirement to determine when to expire versions of the object at the target storage. The source and target retention requirements for versions of the object are different. The source retention policy is used to expire at least one version of the object at the source storage to satisfy the at least one source retention requirement. A number of the versions of the object maintained at the source storage and target storage differ due to the different source and target retention requirements.

摘要： Data objects are replicated from a source storage managed by a source server to a target storage managed by a target server. A source list is built of objects at the source server to replicate to the target server. The target server is queried to obtain a target list of objects at the target server. A replication list is built indicating objects on the source list not included on the target list to transfer to the target server. For each object in the replication list, data for the object not already at the target storage is sent to the target server and metadata on the object is sent to the target server to cause the target server to include the metadata in an entry for the object in a target server replication database. An entry for the object is added to a source server replication database.

A source list is built of objects at the source server to replicate to the target server. The target server is queried to obtain a target list of objects at the target server. A replication list is built indicating objects on the source list not included on the target list to transfer to the target server. For each object in the replication list, data for the object not already at the target storage is sent to the target server and metadata on the object is sent to the target server to cause the target server to include the metadata in an entry for the object in a target server replication database. An entry for the object is added to a source server replication database.

摘要： A chunk index has information on chunks in a storage space referenced in objects in the storage space. The chunk index includes a reference count for each chunk indicating a number of objects in which the chunk is referenced and a reference measurement representing a level of data object references to the chunk. One chunk is selected to remove from the storage space based on a criteria applied to the reference measurements of chunks having reference counts indicating that the chunks are not referenced in one object in the storage space.
