Abstract: A method for execution by a distributed storage network begins by receiving a request to transfer a copy of a set of encoded data slices from at least some associated virtual storage vaults to a destination virtual storage vault and continues by determining whether the destination storage unit supports a source virtual storage vault of the at least some source virtual storage vaults. When the destination storage unit supports the source virtual storage vault the method continues by determining a sub-set of encoded data slices of the set of encoded data slices for transfer and finally, by facilitating sending the sub-set of encoded data slices to the destination storage unit.

Abstract: A method begins with a processing module obtaining a data object from a user and identifying a plurality of virtual storage vaults (VSVs) for storage of the data object. The method continues with the processing module determining dispersal error encoding parameters associated with a first virtual storage vault and error encoding the data object in accordance with those dispersal error encoding parameters to produce a corresponding plurality of sets of encoded data slices (EDSs), issuing write slice requests for the EDSs and receiving EDS information from at least some of the plurality of VSVs. When the EDS information indicates that a threshold number of VSVs have successfully stored the plurality of sets of encoded data slices within a synchronization timeframe, the method continues with the processing module issuing a favorable response to the user, or when a threshold number of VSVs have not successfully stored the plurality of sets of encoded data slices initiating a retry process.

Abstract: A method for execution on a storage network begins with receipt of a data object for storage by a plurality of users and continues with a storage network processing unit determining whether the data object is associated with a replica storage node of a plurality of replica storage nodes associated with the storage network. When the data object is associated with a replica storage node, the method continues by facilitating storing the data object in each replica storage node of the plurality of replica storage nodes and receiving a plurality of access responses from at least some replica storage nodes of the plurality of replica storage nodes. The method then continues by determining whether an access response threshold number of access responses have been received and finally, in response to a determination that an access response threshold number of access responses have been received, transmitting an acknowledgement to the plurality of users.

Abstract: A method for execution by storage network begins by identifying a subset of encoded data slices stored in a set of storage units for enhanced access and interpreting registry data to determine a listing type. The method continues by generating listing slice names for the subset of encoded data slices based on the listing type and sending the listing slice names to the set of storage units, where each storage unit updating storage and/or listing of at least some of the subset of encoded data slices associated with the storage unit based on the listing type and each storage unit issuing slice access information to a requesting entity in response to one or more slice access requests in accordance with the listing type for some of the subset of encoded data slices and the requesting entity receiving slice access information from at least some of the set of storage units.

Abstract: A method includes identifying an existing logical storage vault having existing dispersed storage coding properties for vault transformation, where a first set of storage units support the existing logical storage vault, and a data object of first data objects stored within the first set of storage units is stored as a first plurality of sets of encoded data slices in accordance with the existing dispersed storage coding properties. The method includes identifying a new logical storage vault having new dispersed storage coding properties, wherein storage units support the new logical storage vault. The method includes transforming the first data objects from being in accordance with the existing dispersed storage coding properties to being in accordance with the new dispersed storage coding properties to produce transformed first data objects. The method includes storing the transformed first data objects in the new logical storage vault supported by the storage units.
