Embodiment 1

[0038] A data disaster recovery method between different backup domains, comprising the following steps:

[0039] S1: Use Netbackup to generate source backup domain data;

[0040] S2: Confirm the data type of sending the data in the source backup domain to the target backup domain;

[0041] S3: The target backup domain receives data from the source backup domain.

[0042] Further, the specific process of the step S1 is as follows:

[0043] S11: Build data deduplication in the source backup domain;

[0044] S12: configure the source storage server;

[0045] S13: configure the source deduplication storage unit;

[0046] S14: Configuring communication between the source backup domain and the target domain;

[0047] S15: Configure the sending source backup domain backup data.

[0048] Further, the specific process of the step S2 is as follows:

[0049] Confirm whether the data sent from the source backup domain to the target backup domain is the production data of the backu...

Embodiment 2

[0058] Such as Figure 1-2 As shown, a data disaster recovery system between different backup domains includes several Netbackup backup domains, and each Netbackup backup domain includes a Netbackup master server, a media server and a client, and the media server includes several storage media units ; Netbackup master server completes data backup, archiving and restoration; media server manages its storage media unit; client completes selection and reading data from storage unit;

[0059] The Netbackup master server in any Netbackup backup domain generates the source backup domain data, stores the source backup domain data in its storage medium unit and sends it to the storage medium unit of the media server in another Netbackup backup domain, and receives the source backup Netbackup backup domain data The Netbackup master server in the domain backs up, archives, and restores the source backup domain data.

[0060] Further, the arbitrary one or more Netbackup backup domains s...

Abstract

The invention provides a data disaster tolerance method and system between different backup domains. The system generates source backup data through a Netbackup main server in any Netbackup backup domain, and after it is confirmed that the data in the source backup domain is sent to the data type of the target backup domain, the source backup data is copied and sent to another or multiple Netbackup backup domains; any client side browses and selects the needed backup data, the netbackup main server in the Netbackup backup domain where the backup data is located searches the Netbackup backup domain where the backup data is located or other Netbackup backup domains for the needed data, and the data is restored into a storage medium of the client side. Cross-backup-domain data transmission is achieved, one-to-many, many-to-one and many-to-many transmission modes are supported, the speed is high, and storage space and copying bandwidth are saved.

Description

technical field [0001] The present invention relates to the field of data protection, more specifically, to a data disaster recovery method and system between different backup domains. Background technique [0002] With the rapid development of backup technology, data is getting more and more attention from enterprises. The most precious wealth of business systems is data. To ensure the continuous operation of business systems, it is necessary to protect computer-based data from loss. Human errors, hard disk damage, computer viruses, natural disasters, etc. may cause data loss and cause immeasurable losses to the enterprise. For business systems with a large amount of data, due to their own particularity, the loss of business data in computer systems is a catastrophe, which will lead to the loss of system files, customer information, and business data, making it difficult for business systems and daily work to proceed normally. At this time, the most critical issue is how t...
