METHOD AND DEVICE FOR IMPLEMENTATION DATA REDUNDANCY

摘要

Provided are a method and device for implementing data redundancy. The method includes: a storage strategy identifier of data to be stored is acquired; and the data to be stored is stored in a storage manner corresponding to the storage strategy identifier, wherein the storage strategy identifier is used for indicating the data to be stored is stored in at least one of the following storage manners: a copy redundancy processing manner and an eraser encoding and decoding processing manner. The problem of incapability of ensuring a higher storage space utilization rate in the related art is solved, so that the security and reliability of the data are ensured, meanwhile, the utilization rate of a storage space is increased, and data redundancy implementation flexibility is improved.

1. A method for implementing data redundancy, comprising:
acquiring a storage strategy identifier of data to be stored; and storing the data to be stored in a storage manner corresponding to the storage strategy identifier, wherein the storage strategy identifier is used for indicating to store the data to be stored in at least one of the following storage manners: a replication redundancy processing manner, an erasure encoding and decoding processing manner.
