Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of embodiments of the present application, instead of all the embodiments.It is based on
Embodiment in the application, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall in the protection scope of this application.
First below to the invention relates to concept simply introduced.
Ceph, a kind of distributed memory system；
NAS (Network Attached Storage), network attached storage；
SAN (Storage Area Network), storage area network；
Rbd-rados device block, block device management.
Fig. 1 is that a kind of distributed memory system disk snapshot restoration methods process that the application specific embodiment provides is shown
It is intended to, as shown in Figure 1, it is mainly included the following steps that.
Step S101: when needing to restore snapshot, protecting the snapshot to be restored in source book, obtains protection snapshot,
The protection snapshot is configured as not deleting.
Step S102: clone volume is created according to the protection snapshot, the clone volume, protection snapshot and source book store chain type
Relationship is both configured to not delete.
Step S103: the pointer of disk is directed toward the clone volume, the read-write of data is carried out by the clone volume.
First snapshot is protected when carrying out snapshot recovery using method provided by the embodiments of the present application, prevents from being missed
It deletes, is then based on the protection snapshot and carries out quickly link clone, the pointer of disk is directed toward clone volume, data writes after recovery
Enter and read all by clone volume, to achieve the effect that restore data, improves snapshot and restore efficiency.
It is described in detail below in conjunction with specific embodiment.
Fig. 2 is a kind of distributed memory system disk snapshot and restoration scenario schematic diagram provided by the embodiments of the present application,
Source book is shown in Fig. 2, which can be rbd disk, and all data of virtual machine are all written in source book.When creation snapshot
When, snapshot 1, snapshot 2 ... snapshot N are generated using the inside snapshot command that rbd disk provides, these snapshots are relationships arranged side by side,
Snapshot metadata information therein is recorded in source book, and there is the letter such as timing node and data distribution bitmap of each snapshot in the inside
Breath；Restored when needing to restore snapshot, such as using snapshot 1, need first to protect snapshot 1, not in shielded snapshot 1
It can be deleted；Then the operation for restoring snapshot 1 is executed, a new clone volume, clone volume can be generated according to protection snapshot 1 at this time
It is that there are chain relationships, therefore after carrying out recovery snapshot operation, protect snapshot 1 and source book not with protection snapshot 1 and source book
It can delete；It is last if necessary to carry out snapshot 4, snapshot 5 ... snapshot M to the disk after recovery, snapshot metadata information is just at this time
It will record in clone volume, clone volume at this time is equivalent to source book, and the read-write of data is all stored in clone volume.
Wherein, it before carrying out snapshot recovery, needs to be the reason of first protecting snapshot, prevents the later period from accidentally deleting the snapshot,
Chain structure is caused to be interrupted, the problem of loss of data.In addition, other than the snapshot in guard mode, other snapshot nodes
It can delete.
After restoring snapshot, subsequent all data can all be write in clone volume, no longer be write in original disk, the later period pair
Clone volume carries out snapshot and restores similar with original disk, and details are not described herein.
In the embodiment of the present application, the scheme based on primary ceph block device disk snapshot improves, when being created
It is still based on snapshot inside ceph when snapshot, but when carrying out snapshot recovery, first snapshot is protected, prevents from accidentally being deleted,
The snapshot for being then based on the protection carries out quickly link clone, the pointer of disk is directed toward clone volume, data writes after recovery
Enter and read all by clone volume, to achieve the effect that restore data.
It is corresponding with above method embodiment, restore to fill present invention also provides a kind of distributed memory system disk snapshot
It sets, described device includes:
It is fast to obtain protection for being protected to the snapshot to be restored in source book when needing to restore snapshot for protective module
According to the protection snapshot is configured as not deleting；
Cloning module, for creating clone volume, the clone volume, protection snapshot and source book storage according to the protection snapshot
Chain relationship is both configured to not delete；
