Abstract

A method begins by a processing module determining that a data storage request is a cloud data storage request. The method continues with the processing module determining at least one of a cloud storage access reliability indication and a cloud storage data reliability indication for the data storage request. The method continues with the processing module sending the data storage request and the at least one of cloud storage access reliability indication and cloud storage data reliability indication to a cloud storage system.

Claims

1. A method comprises:

creating, by a user device, a cloud data storage request that includes data for storing and at least one of a cloud storage access reliability indication and a cloud storage data reliability indication;

sending, by the user device, the cloud data storage request to a cloud storage system;

interpreting, by a device of the cloud storage system, the at least one of cloud storage access reliability indication and the cloud storage data reliability indication to determine at least one of a storage access level and a storage reliability level;

determining, by the device of the cloud storage system, dispersed storage error encoding parameters based on the at least one of the storage access level and the storage reliability level;

encoding, by the device of the cloud storage system, the data based on the dispersed storage error encoding parameters to produce one or more sets of encoded data slices; and

storing, by storage units of the cloud storage system, the one or more sets of encoded data slices.

2. The method of claim 1, wherein the creating the cloud data storage request comprises:

obtaining, from the cloud storage system, a cloud storage menu that provides a range of access for the storage access level available within the cloud storage system and a range of reliability for the storage reliability level available within the cloud storage system;

receiving at least one of;

a selection of an access for the storage access level to provide the cloud storage access reliability indication; and

a selection of a reliability for the storage reliability level to provide the cloud storage data reliability indication.

3. The method of claim 1, wherein the creating the cloud data storage request comprises:

determining a data type for the data; and

accessing a user register to obtain at least one of a user setting for the cloud storage access reliability indication for the data type and a user setting for the cloud storage data reliability indication for the data type;

or

accessing a system register to obtain at least one of a system setting for the cloud storage access reliability indication for the data type and a system setting for the cloud storage data reliability indication for the data type.

4. The method of claim 1, wherein the creating the cloud data storage request comprises:

determining an application type that generated the data; and

accessing a user register to obtain at least one of a user setting for the cloud storage access reliability indication for the application type and a user setting for the cloud storage data reliability indication for the application type;

or

accessing a system register to obtain at least one of a system setting for the cloud storage access reliability indication for the application type and a system setting for the cloud storage data reliability indication for the application type.

5. The method of claim 1, wherein the creating the cloud data storage request comprises at least one of:

accessing a first register to obtain at least one of a default system setting for the cloud storage access reliability indication and a default system setting for the cloud storage data reliability indication; and

accessing a second register to obtain at least one of a user-defined default setting for the cloud storage access reliability indication and a user-defined default setting for the cloud storage data reliability indication.

6. The method of claim 1 further comprises:

the cloud storage access reliability indication including at least one of;

level of availability of data of the data storage request;

storage cost information;

a redundant array of independent disks (RAID) preference indicator; and

a data dispersal preference indicator;

the cloud storage data reliability indication including at least one of;

a data loss cost consequence;

a data loss tolerance level;

the storage cost information;

the RAID preference indicator; and

the data dispersal preference indicator.

7. A computer readable storage medium comprises:

a first storage device that stores operational instructions that, when executed by a processing module of a user device, causes the processing module of the user device to;

create a cloud data storage request that includes data for storing and at least one of a cloud storage access reliability indication and a cloud storage data reliability indication for the data storage request; and

send the cloud data storage request to a cloud storage system;

a second storage device that stores operational instructions that, when executed by a processing module of a device of the cloud storage system, causes the processing module of the device of the cloud storage system to;

interpret the at least one of cloud storage access reliability indication and the cloud storage data reliability indication to determine at least one of a storage access level and a storage reliability level;

determine dispersed storage error encoding parameters based on the at least one of the storage access level and the storage reliability level;

encode the data based on the dispersed storage error encoding parameters to produce one or more sets of encoded data slices; and

a third storage device that stores operational instructions that, when executed by a processing module of a storage unit of the cloud storage system, causes the processing module of the storage unit to;

store an encoded data slice of at least one of the one or more sets of encoded data slices.

8. The computer readable storage medium of claim 7, wherein the first storage device further stores operational instructions that, when executed by a processing module of a user device, causes the processing module of the user device to:

obtain, from the cloud storage system, a cloud storage menu that provides a range of access for the storage access level available within the cloud storage system and a range of reliability for the storage reliability level available within the cloud storage system;

receive at least one of;

a selection of an access for the storage access level to provide the cloud storage access reliability indication; and

a selection of a reliability for the storage reliability level to provide the cloud storage data reliability indication.

9. The computer readable storage medium of claim 7, wherein the first storage device further stores operational instructions that, when executed by a processing module of a user device, causes the processing module of the user device to:

determine a data type for the data; and

access a user register, of the memory, to obtain at least one of a user setting for the cloud storage access reliability indication for the data type and a user setting for the cloud storage data reliability indication for the data type;

or

access a system register, of the memory, to obtain at least one of a system setting for the cloud storage access reliability indication for the data type and a system setting for the cloud storage data reliability indication for the data type.

10. The computer readable storage medium of claim 7, wherein the first storage device further stores operational instructions that, when executed by a processing module of a user device, causes the processing module of the user device to:
