Abstract

A method includes obtaining a data object for storage. The method further includes generating a data object identifier for the data object. The method further includes determining a vault for storing the data object. The method further includes generating a source name for the data object based on the data object identifier and a vault identifier. The method further includes dispersed storage error encoding the data object to produce a plurality of sets of encoded data slices. The method further includes generating a plurality of sets of slice names, wherein each of the slice names of the plurality of slice names includes the source name. The method further includes sending, in accordance with the plurality of sets of slice names, the plurality of sets of encoded data slices to a set of storage units of the DSN that supports the vault for storage therein.

Claims

1. A method for execution by a computing device of a dispersed storage network (DSN), the method comprises:

obtaining a data object for storage in the DSN;

generating a data object identifier for the data object;

determining a vault of the DSN for storing the data object;

generating a source name for the data object based on the data object identifier and a vault identifier, which identifies the vault;

dispersed storage error encoding the data object to produce a plurality of sets of encoded data slices;

generating a plurality of sets of slice names for the plurality of sets of encoded data slices, wherein each of the slice names of the plurality of slice names includes the source name; and

sending, in accordance with the plurality of sets of slice names, the plurality of sets of encoded data slices to a set of storage units of the DSN that supports the vault for storage therein.

2. The method of claim 1, wherein the obtaining the data object comprises one of:

receiving the data object from a second computing device of the DSN; and

generating, by the computing device, the data object.

3. The method of claim 1, wherein the generating the data object identifier comprises:

performing a hash function on the data object to produce the data object identifier.

4. The method of claim 1 further comprises:

determining the vault identifier based on user information affiliated with a source of the data object.

5. The method of claim 1 further comprises:

generating the source name to further include a vault generation indicator.

6. The method of claim 1, wherein the dispersed storage error encoding the data object further comprises:

dispersed storage error encoding the data object in accordance with dispersed storage error encoding parameters that include a pillar width number and a decode threshold number, wherein pillar width number corresponds to a total number of encoded data slices in a set of encoded data slices and the decode threshold number is a minimum number of encoded data slices of the set of encoded data slices needed to recover a corresponding data segment of the data object.

7. The method of claim 1, wherein a slice name of the plurality of sets of slice names comprises:

a pillar number identifier;

a segment identifier; and

the source name.

8. A computing device comprises:

an interface;

memory; and

a processing module operably coupled to the memory and the interface, wherein the processing module is operable to;

obtain a data object for storage in the DSN;

generate a data object identifier for the data object;

determine a vault of the DSN for storing the data object;

generate a source name for the data object based on the data object identifier and a vault identifier, which identifies the vault;

dispersed storage error encode the data object to produce a plurality of sets of encoded data slices;

generate a plurality of sets of slice names for the plurality of sets of encoded data slices, wherein each of the slice names of the plurality of slice names includes the source name; and

send, via the interface and in accordance with the plurality of sets of slice names, the plurality of sets of encoded data slices to a set of storage units of the DSN that supports the vault for storage therein.

9. The computing device of claim 8, wherein the processing module is operable to obtain the data object by performing one of:

receiving, via the interface, the data object from a second computing device of the DSN; and

generating, by the computing device, the data object.

10. The computing device of claim 8, wherein the processing module is operable to generate the data object identifier by:

performing a hash function on the data object to produce the data object identifier.

11. The computing device of claim 8, wherein the processing module is further operable to:

determine the vault identifier based on user information affiliated with a source of the data object.

12. The computing device of claim 8, wherein the processing module is further operable to:

generate the source name to further include a vault generation indicator.

13. The computing device of claim 8, wherein the processing module is operable to dispersed storage error encode the data object by:

dispersed storage error encoding the data object in accordance with dispersed storage error encoding parameters that include a pillar width number and a decode threshold number, wherein pillar width number corresponds to a total number of encoded data slices in a set of encoded data slices and the decode threshold number is a minimum number of encoded data slices of the set of encoded data slices needed to recover a corresponding data segment of the data object.

14. The computing device of claim 8, wherein a slice name of the plurality of sets of slice names comprises:

a pillar number identifier;

a segment identifier; and

the source name.
