Abstract
A technique includes communicating signatures of samples of first data associated with an object to at least some stores of a plurality of stores on which the object is distributed, and in response to the communication, receiving responses indicating numbers of the samples stored on the respective at least some of the plurality of stores and regulating on which store of the plurality of stores deduplicated data associated with the first data is stored based at least in part on the numbers and a pattern of data storage on the stores.
Claims15
A method comprising:
- communicating signatures of samples of first data associated with an object to at least some stores of a plurality of stores on which the object is distributed;
- in response to the communication, receiving responses indicating numbers of the samples stored on the respective at least some of the plurality of stores;
- and
- regulating on which store of the plurality of stores deduplicated data associated with the first data is stored based at least in part on the numbers and a pattern of data storage on the stores.
A system comprising:
- a backup application comprising a processor to designate first data associated with an object to be backed up, the object being stored on a plurality of stores in a distributed fashion;
- and
- a client application to:
- in response to the first data, communicate signatures of samples of the first data to a plurality of stores on which the object is distributely stored;
- receive responses from the plurality of stores indicating numbers of the samples stored on the respective at least some of the plurality of stores;
- and
- regulate on which store of the plurality of stores deduplicated data associated with the first data is stored based at least in part on the numbers and a pattern of data storage on the stores.
An article comprising a computer readable non-transitory storage medium to stored instructions that when executed by the computer cause the computer to:
- communicate signatures of samples of first data associated with an object to at least some stores of a plurality of stores on which the object is distributed;
- in response to the communication, receive responses indicating numbers of the samples stored on the respective at least some of the plurality of stores;
- and
- regulate on which store of the plurality of stores deduplicated data associated with the first data is stored based at least in part on the numbers and a pattern of data storage on the stores.
