Abstract
The invention relates to the field of data memory technologies and discloses an asynchronous remote copy method for a memory. The method comprises the following steps of scribing data in a local memory to a plurality of pieces of data, respectively time-stamping each piece of data and automatically synchronizing the pieces of data in the local memory to a remote memory at every one synchronizing cycle. Through scribing the data to the pieces of data, time-stamping each piece of data and directly obtaining the pieces of data of the corresponding time stamp from the local memory to be copied to the remote memory in a copy process, the time delay is reduced and the data relocation efficiency is greatly improved.
Description
Technical field
The present invention relates to technical field of data storage, a kind of storer asynchronous remote copying method.
Background technology
In computer data storing process, in order to ensure the safety of data, often need to carry out asynchronous remote copy to data, traditional asynchronous remote copying method is by block copy many parts, and by many numbers according to copying, and need after all copy replications complete, just complete write operation, this mode needs repeatedly to write, and greatly reduces the efficiency of data resettlement.
Summary of the invention
Solve the problems of the technologies described above, the invention provides a kind of storer asynchronous remote copying method, by data scribing, be divided into multiple data slice, and timestamp is stamped to each data slice, in reproduction process, the data slice directly obtaining corresponding timestamp from local storage copies in remote memory, reduce time delay, greatly improve data resettlement efficiency.
In order to achieve the above object, the technical solution adopted in the present invention is, a kind of storer asynchronous remote copying method, comprising:
By the data scribing in local storage, be divided into multiple data slice, and respectively timestamp stamped to each data slice,
Whenever a synchronizing cycle of interval, then automatic data slice in local storage to be synchronized in remote memory.
Further, local storage is divided into primary memory and from storer, after local storage and remote memory set up asynchronous remote copy relation, start initial synchronisation, and the data slice full dose of primary memory is copied to from storer, after initial synchronisation completes, from data mode and the main memory data state consistency of storer.
The present invention is by adopting technique scheme, compared with prior art, tool has the following advantages: the present invention passes through data scribing, be divided into multiple data slice, and timestamp is stamped to each data slice, in reproduction process, the data slice directly obtaining corresponding timestamp from local storage copies in remote memory, reduce time delay, greatly improve data resettlement efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiments of the invention.
Embodiment
Now the present invention is further described with embodiment by reference to the accompanying drawings.
As a specific embodiment, first Fig. 1 illustrates the apparatus structure schematic diagram that a kind of storer asynchronous remote copying method of the present invention embodies, this structural representation embodies the implementation procedure of storer asynchronous remote copy, local storage is connected with multiple local data base, remote memory is connected with multiple remote data base, and asynchronous remote copy between storer will be realized, it is then the backup by realizing data between local storage and remote memory, local storage extracts data from local data base, the data received are stored in remote data base by remote memory.
A kind of storer asynchronous remote copying method of the present invention, comprising:
By the data scribing in local storage, be divided into multiple data slice, and respectively timestamp stamped to each data slice,
Whenever a synchronizing cycle of interval, then automatic data slice in local storage to be synchronized in remote memory.
In the present embodiment, local storage is divided into primary memory and from storer, after local storage and remote memory set up asynchronous remote copy relation, start initial synchronisation, and the data slice full dose of primary memory is copied to from storer, after initial synchronisation completes, from data mode and the main memory data state consistency of storer.
The data of local storage are transferred in the equipment of remote storage area and back up, and provide data long-distance disaster function, guarantee data security, and are convenient to the quick self-recovery of data.
Although specifically show in conjunction with preferred embodiment and describe the present invention; but those skilled in the art should be understood that; not departing from the spirit and scope of the present invention that appended claims limits; can make a variety of changes the present invention in the form and details, be protection scope of the present invention.
Claims (2)
1. a storer asynchronous remote copying method, is characterized in that: comprising:
By the data scribing in local storage, be divided into multiple data slice, and respectively timestamp stamped to each data slice,
Whenever a synchronizing cycle of interval, then automatic data slice in local storage to be synchronized in remote memory.
2. a kind of storer asynchronous remote copying method according to claim 1, it is characterized in that: local storage is divided into primary memory and from storer, after local storage and remote memory set up asynchronous remote copy relation, start initial synchronisation, and the data slice full dose of primary memory is copied to from storer, after initial synchronisation completes, from data mode and the main memory data state consistency of storer.
