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.

Replication of versions of an object from a source storage to a target storage

A copy procedure detects qualified data objects in a body of source data, and copies the source data to a target storage unit except for unqualified data objects, which are replaced with a prescribed bit pattern. Following completion of the backup, a record is prepared indicating that all data objects exist in the specified target storage, regardless of whether each data object was replaced with a predetermined bit pattern rather than being physically written to the specified target storage. This process may, be repeated in order to perform data reclamation, effectively removing user files no longer qualifying for backup.

Copy process substituting compressible bit pattern for any unqualified data objects

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.

Using geographical location information to provision multiple target storages for a source device

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.

Replication of data objects from a source server to a target server

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.

Using geographical location information to provision a target storage for a source device

Provided are techniques for managing backup operations from a client system to a primary server and secondary server. A determination is made at the client system of whether a state of the data on the secondary server permits a backup operation in response to determining that the primary server is unavailable when a force failover parameter is not set. The client system reattempts to connect to the primary server to perform the backup operation at the primary server in response to determining that the state of the data on the secondary server does not permit the backup operation. The client system performs the backup operation at the secondary server in response to determining that the state of the secondary server permits the backup operation.
