Embodiment 1

[0063] The operating system used in the production environment of this example is RedHat Enterprise 5, the production data uses 1000 data files with a file size of 1GB, and the IP of the production environment is 172.17.2.20. The cluster environment includes 3 nodes, the cluster VIP is 172.17.1.10, and the cluster node IPs are 172.17.1.11, 172.17.1.12, and 172.17.1.13. Assume that the node where the VIP is located is 172.17.1.11, that is, the node 172.17.1.11 is the master node. The operating systems of all nodes in the cluster environment are RedHat Enterprise 5.

[0064] The name of the client module is tsClient, and it is deployed on the 172.17.2.20 environment; the name of the metadata management module is tsMeta, and it is deployed on the three nodes of the cluster; the name of the data reading and writing module is tsData, and it is deployed on the three nodes of the cluster;

[0065] The name of the node management module is tsNode, which are deployed on the three node...

Abstract

The invention relates to a cluster-supported magnetic tape backup system and a method thereof. The cluster-supported magnetic tape backup system comprises a client module, a metadata management module, a data read-write module and a node management module, and also comprises a magnetic tape management module which is used for the management of a magnetic tape, a magnetic tape library and a magnetic tape medium set, and a service management module which is used for managing the service of the tape backup system. The method comprises a data backup process and a data recovery process, wherein thedata backup process comprises a magnetic tape read-write initialization step and a magnetic tape full-write detection step, and the data recovery process comprises a magnetic tape availability detection step. Compared with the prior art, the cluster-supported magnetic tape backup system can actively and effectively help a user to complete data protection more quickly and timely, so that more material cost and manpower cost are saved, and the cluster-supported magnetic tape backup system has the advantages of good practicability, high reliability, low cost, small size, high safety and the like.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a cluster-supporting tape backup system and a method thereof. Background technique [0002] As computers continue to evolve, so does data protection. However, with the rapid increase of data, data protection becomes more and more difficult, and the cost of storing data becomes larger and larger. [0003] Data backup refers to saving the data in the computer management system to some kind of storage medium in an appropriate way, so as to keep a back-up backup for the data in the hard disk, so that when the hard disk data is damaged or needs to use the data that has been deleted from the hard disk Data can be restored. The media used to store backups mainly include floppy disks, hard disks, tapes, and recordable CDs. Under the condition of the same capacity, tape has the lowest cost and the smallest volume, and the tape itself is highly secure, so tape has been the most widely used s...
