Problems solved by technology

If a large-capacity backup device is used, such as tape, although the capacity can be guaranteed and the price is relatively low, the data read and write rate is low, which cannot meet the large-capacity data backup needs.

Embodiment 1

[0063] Such as figure 1 As shown, the present invention provides a deduplication-based tape archiving system, including a business data generation module 1, a backup server 2 and a physical tape library 3;

[0064] The backup server 2 is provided with a disk, a deduplication module 4, a unique data storage pool 5 and a deduplication calculation module 6;

[0065] The only data storage pool 5 is set on the disk;

[0066] The deduplication module 4 is used to receive the backup data file generated by the business data module 1, and delete the duplicate data existing in the unique data storage pool, obtain the unique data, and store the unique data in the unique data storage pool 5;

[0067] The repeated data calculation module 6 is used to calculate the backup repetition rate of the unique data in the unique data storage pool 5, and migrate the unique data whose backup repetition rate is lower than the threshold to the physical tape library 3, and release the disk space of the ...

Embodiment 2

[0069] Such as figure 2 As shown, the present invention provides a tape archiving system based on deduplication, including a business data generation module 1, a backup server 2, a physical tape library 3 and an optical fiber switch 7;

[0070] The backup server 2 is provided with a disk, a deduplication module 4, a unique data storage pool 5 and a deduplication calculation module 6;

[0071] The only data storage pool 5 is set on the disk;

[0072] The deduplication module 4 is used to receive the backup data file generated by the business data module 1, and delete the duplicate data existing in the unique data storage pool to obtain the unique data, and then store the unique data in the unique data storage pool 5, Release the disk space of the unique storage pool 5; the data deduplication module 4 includes:

[0073] The backup data receiving unit 4.1 is used to receive the backup data file generated by the business data module;

[0074] A data block division unit 4.2 is ...

Embodiment 3

[0085] Such as image 3 As shown, the present invention provides a kind of tape archiving method based on deduplication, comprising the following steps:

[0086] S1. The data deduplication module receives the backup data file generated by the business data module, and deletes the duplicate data that already exists in the unique data pool, obtains the unique data, and then stores the unique data in the unique data storage pool;

[0087] S2. The repeated data calculation module calculates the backup repetition rate of the unique data in the unique data storage pool, and migrates the unique data whose backup repetition rate is lower than the threshold to the physical tape library, releasing the disk space of the unique data storage pool. The customer's business application will inevitably generate duplicate content over time. For these duplicate data, we can obtain unique data through deduplication, and we can back it up to the disk-based primary storage area, because the high-sp...

Abstract

The invention provides a magnetic tape archiving system and method based on repeated deletion. The system comprises a service data generation module, a backup server and a physical tape library; the backup server is provided with a disk, a repeated data deleting module, a unique data storage pool and a repeated data calculating module. The unique data storage pool is arranged on the disk; the duplicated data deleting module is used for receiving the backup data file generated by the service data module, deleting duplicated data existing in the unique data storage pool to obtain unique data, and storing the unique data into the unique data storage pool; and the repeated data calculation module is used for calculating the backup repetition rate of the unique data in the unique data storage pool, migrating the unique data of which the backup repetition rate is lower than a threshold value to the physical tape library, and releasing the disk space of the unique storage pool.

Description

technical field [0001] The invention belongs to the technical field of storage systems, and in particular relates to a tape filing system and method based on deduplication. Background technique [0002] The backup device is always full of a large amount of redundant data. The backup device is usually a disk, but the capacity of the backup disk has become saturated, and there is not enough space in the data center to back up PT-level data. In this case Under the circumstances, when we want to save the backup data for one month, we can only save it for two to three days, and the price of the disk is too high. If a large-capacity backup device is used, such as a tape, although the capacity can be guaranteed and the price is relatively low, the data read and write rate is low, which cannot meet the large-capacity data backup needs. How to quickly back up the useful data of customers and save costs is the problem to be solved by the present invention. [0003] This is the defic...
