Description
Technical field
The present invention discloses a kind of new increment asynchronous remote copy design method, is related to long-range technical field of memory.
Background technology
Among actual storage design test, it is found that existing storage system increment remote copy relationship is more clumsy, pacify
Full property deficiency, increment volume and source book are in same Raids groups either on same pool or same external storage system.
Using such a design method, once either RAID groups or Pool delay machine for system where source book, increment will be caused to roll up while delayed
Machine, is not timely received data and causes data imperfect so that increment remote copy exists so as to cause the increment of distal end to be rolled up
There are obvious shortcoming in terms of data protection.And the present invention provides a kind of new increment asynchronous remote copy design method, by increment
Volume is isolated with source book geographical location, improves the protection mechanism of increment volume and source book so that the pool of source book delays after machine, increases
The pool of amount volume still can be normally by the data transfer of increment to opposite end；The pool of increment volume delays after machine, and source book can be automatic
Regenerating new increment volume, asynchronous relationship is lost or asynchronous data is lost without causing.
The content of the invention
Demand and shortcoming of the present invention for the development of current technology, there is provided a kind of new increment asynchronous remote copy is set
Meter method, avoids many drawbacks that source book is rolled up machine of delaying with increment and produced during asynchronous remote copy, is worth promoting.
A kind of new increment asynchronous remote copy design method, increment volume is set up separately from source book and is set in different being locally stored
It is standby upper, increment volume is physically separated with source book, increment volume pass through FC either the transmission mode of IP or wireless network according to
Asynchronous transmission time interval is transferred data in remote storage automatically according to the degree of saturation of the existing performance of storage system.
In the method when increment volume is transferred data in remote storage by the transmission mode of wireless network,
End and remote storage end configuration wireless transport module is locally stored.
Wireless transport module is NRF24LE1 wireless transport modules or NRF905 wireless transport modules in the method.
A capacity is marked off in the method in remote storage less than or equal to the data block of source book as storage to increase
Measure the data protection space of volume.
Remote storage is server or external storage device in the method.
External storage device is USB flash disk or external hard disk in the method.
The volume of increment described in the method sets multiple backups.
The present invention has an advantageous effect in that compared with prior art：
The present invention provides a kind of new increment asynchronous remote copy design method, and increment is rolled up and is set up separately from source book in different locals
In storage device, increment volume is set to be physically separated with source book, increment volume passes through the FC either transmission sides of IP or wireless network
Formula transfers data to remote storage automatically according to asynchronous transmission time interval according to the degree of saturation of the existing performance of storage system
In；Increment is rolled up using the method for the present invention and is isolated with source book geographical location, improves the protection mechanism of increment volume and source book,
So that the pool of source book delays after machine, the pool of increment volume still can be normally by the data transfer of increment to opposite end；Increment volume
Pool delays after machine, and source book can regenerate new increment volume automatically, and without causing, asynchronous relationship is lost or asynchronous data is lost
Lose.

Embodiment
The present invention provides a kind of new increment asynchronous remote copy design method, and increment is rolled up and is set up separately from source book different
On local memory device, increment volume is set to be physically separated with source book, increment volume passes through the FC either biographies of IP or wireless network
Defeated mode transfers data to distal end automatically according to asynchronous transmission time interval according to the degree of saturation of the existing performance of storage system
In storage.
For the object, technical solutions and advantages of the present invention are more clearly understood, below in conjunction with specific embodiment, to this hair
Bright further description.
Using the method for the present invention, increment is rolled up and is set up separately from source book on different local memory devices, make increment volume and source
Volume is physically separated, and source book can be arranged in server storage, and increment volume can be arranged on external USB flash disk or one only
Stand on the external hard disk of storage system, increment volume by FC either the transmission mode of IP or wireless network according to asynchronous transmission
Time interval is transferred data in remote storage automatically according to the degree of saturation of the existing performance of storage system；
Wherein when increment volume transferred data to by the transmission mode of wireless network in remote storage when, be locally stored hold and
Remote storage end, which configures wireless-transmission network and wireless transport module, wireless transport module, to select NRF24LE1 to be wirelessly transferred
Module or NRF905 wireless transport modules, are locally stored the data rolled up increment by wireless transport module at end with electromagnetic wave
Form is transferred to remote storage end；With reference to 2 schematic diagram of figure；
Remote storage end can be a server, and the data block that a capacity is less than or equal to source book is marked off on this server
As the data protection space of storage increment volume, i.e. increment volume can be the automatic simplification volume consistent with source book amount of capacity；
And increment can be rolled up and multiple backups are set, for example set mirror mirror images to carry out multiple protective.
Therefore the method for the present invention is utilized, even if the pool of source book delays after machine, the pool of increment volume still will normally can increase
The data transfer of amount is to opposite end；The pool of increment volume delays after machine, and source book can regenerate new increment automatically and roll up without causing
Asynchronous relationship is lost and asynchronous data is lost.In addition, the data of increment volume are put among external USB flash disk or mobile hard disk, increase
More points of increment copies, increase the ability of data protection.
And above are only the citing implemented of the present invention, under technical solution of the present invention, can according to actual conditions correspondingly into
Row adjustment, for example when choosing FC transmission modes, the setting of optical-fibre channel end and remote storage end is being locally stored accordingly is carried out, with
Just carry out data transmission.Therefore in addition to technical scheme, involved technology is the prior art, does not tire out one by one and states.
