Embodiment Construction

[0021] The present invention will be further explained below in conjunction with the accompanying drawings.

[0022] This embodiment is based on mainstream linux systems, such as debian / ubuntu of deb series or redhat / centos of rpm series, etc. Such as figure 1 As shown, the process of adding NAS storage in this embodiment mainly includes the following steps:

[0023] Step 11: Map the storage space of the NAS service to the local through the network protocol nfs or cifs protocol, and then convert the storage space mapped to the local NAS service into a device block through fuse (user space file system) technology; directly treat it as a local device use. Fuse technology is a set of API interfaces provided by linux, which can make logical devices. Usually, the storage space of each NAS service is a file directory on the server side, and a directory can be converted into a local basic device. A directory can also be converted into multiple local basic devices, that is, multip...

Abstract

The invention belongs to the technical field of computers, and discloses a file-level data backup method for an NAS service. According to the present invention, by the network mapping, the storage space of the NAS service is directly led to the local and is used by a local server, the mapping storage space of the NAS is converted into the local equipment through an FUSE related technology, and then the data backup based on the NAS service is completed through the combination of a dynamic file system and the NAS service. The invention provides a file-level data recovery method for the NAS service. According to the invention, the backup recovery system of the NAS service is complete in function and more convenient to use as the backup of a traditional server; a user of the NAS service can use the NAS service without mastering an additional operation knowledge system; the client can realize the functions of snapshot, archiving and the like of the NAS service; and the client can quickly recover the data and also can select a recovered time point.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a file-level data backup and recovery method for NAS services. Background technique [0002] A NAS (Network Attached Storage) server is a dedicated data storage server that provides cross-platform file sharing. For the use of NAS service data backup, the industry's traditional practice is to use the interface of the NAS service itself to directly perform data backup and recovery operations, which can meet general backup and recovery scenarios. However, if the customer has further needs, such as restoring data to a specified point in time, or archiving data, the traditional backup and recovery system cannot achieve more data operation functions due to the lack of relevant technical means, and the data recovery time Also very long. At this time, we urgently need to introduce concepts such as snapshots in the local storage solution. [0003] On the other hand, the l...
