Abstract

A computer-implemented method for deduplicating data is disclosed. The method may include identifying a request to transfer data from a client in a deduplication system to a server in the deduplication system. The method may also include determining, based at least in part on performance of the deduplication system, whether to deduplicate the data before transferring the data from the client to the server. The method may further include performing the following, the order of which is based on the determination: deduplicating the data and transferring the data from the client to the server. Various other methods, systems, and computer-readable media are also disclosed.

Claims20

Dependent claims

A computer-implemented method for deduplicating data, at least a portion of the method being performed by a computing device comprising at least one processor, the method comprising:

identifying a request to transfer data from a client in a deduplication system to a server in the deduplication system;
determining whether performing deduplication on the client currently outperforms performing deduplication on the server by:
measuring data throughput while performing deduplication on the client;
measuring data throughput while performing deduplication on the server;
comparing the data throughput while performing deduplication on the client with the data throughput while performing deduplication on the server;
determining, based at least in part on determining whether performing deduplication on the client currently outperforms performing deduplication on the server, whether to perform deduplication of the data on the client before transferring the data from the client to the server or to perform deduplication of the data on the server after transferring the data from the client to the server;
performing the following, the order of which is based on determining whether to perform deduplication of the data on the client before transferring the data from the client to the server or to perform deduplication of the data on the server after transferring the data from the client to the server:
deduplicating the data;
transferring the data from the client to the server.

6 more elements

A system for deduplicating data, the system comprising:

a data-transfer module programmed to:
identify a request to transfer data from a client in a deduplication system to a server in the deduplication system;
transfer the data from the client to the server;
a deduplication module programmed to:
determine whether performing deduplication on the client currently outperforms performing deduplication on the server by:
measuring data throughput while performing deduplication on the client;
measuring data throughput while performing deduplication on the server;
comparing the data throughput while performing deduplication on the client with the data throughput while performing deduplication on the server;
determine, based at least in part on determining whether performing deduplication on the client currently outperforms performing deduplication on the server, whether to perform deduplication of the data on the client before transferring the data from the client to the server or to perform deduplication of the data on the server after transferring the data from the client to the server;
deduplicate the data;
a storage device configured to store the data;
one or more processors configured to execute the data-transfer module and the deduplication module.

9 more elements

A non-transitory computer-readable-storage medium comprising one or more computer executable instructions that, when executed by at least one processor of a computing device, cause the device to:

identify a request to transfer data from a client in a deduplication system to a server in the deduplication system;
determine whether performing deduplication on the client currently outperforms performing deduplication on the server by:
measuring data throughput while performing deduplication on the client;
measuring data throughput while performing deduplication on the server;
comparing the data throughput while performing deduplication on the client with the data throughput while performing deduplication on the server;
determine, based at least in part on determining whether performing deduplication on the client currently outperforms performing deduplication on the server, whether to perform deduplication of the data on the client before transferring the data from the client to the server or to perform deduplication of the data on the server after transferring the data from the client to the server;
perform the following, the order of which is based on determining whether to perform deduplication of the data on the client before transferring the data from the client to the server or to perform deduplication of the data on the server after transferring the data from the client to the server:
deduplicate the data;
transfer the data from the client to the server.
