Embodiment 1

[0033] Such as figure 1 As shown, a method for protecting archived data in a distributed file storage system provided by this embodiment is characterized in that it includes the following steps:

[0034] S1: The timer counts, and the timer realizes the conversion of the file state through timing;

[0035] S2: The file enters the file grace state, and the file permissions in this state are readable, writable, and deleteable;

[0036] S3: The file enters the file protection period. At this time, the file permissions are readable, non-writable, and non-deletable (except for administrators).

[0037] S4: The file enters the file protection expired state, and the file permissions in the file protection expired state are readable, writable, and deleteable.

[0038] In this embodiment, in the step S3:

[0039] Empty files in the protection period state can be modified, and the modified files directly enter the grace period state.

[0040] In this embodiment, in the step S4:

[0...

Embodiment 2

[0046] This embodiment provides a protection archive data system of a distributed file storage system, which is characterized in that it includes:

[0047] Timer, the timer realizes the conversion of the file status through timing;

[0048] File grace state, the file permissions in this state are readable, writable, and deleteable;

[0049] The status of the file protection period. At this time, the file permissions are readable, non-writable, and non-deletable (except for administrators).

[0050] The file protection expired state, the file permissions in the file protection expired state are readable, writable, and deleteable;

[0051] The file first enters the file grace state. When the timer counts to the predetermined time, the file enters the file protection period state. When the timer counts to the predetermined time, the file enters the file protection expiration state.

[0052] In this embodiment, an empty file in the protection period state can be modified, and th...

Abstract

The invention relates to a method and a system for protecting archived data of a distributed file storage system, which are characterized in that the method comprises the following steps: S1, a timeris timed, and the timer realizes the conversion of a file state by the timer; 2, the timer is timed by the timer. S2: the file enters the file grace state, and the file permissions in the state are: readable, writable, and deletable; S3: the file enters the file protection period state, at which time the file permission is readable, non-writable and non-deletable. S4: the file enters the file protection expiration state, and the file permission in the file protection expiration state is, readable, writable and deletable.

Description

technical field [0001] The invention belongs to the technical field of distributed file system design, and in particular relates to a method and system for protecting archived data in a distributed file storage system. Background technique [0002] With the rapid development of the distributed file storage system, the storage capacity has reached PB level, more and more data is stored, and the scope of application is more and more extensive. The distributed file storage system mainly uses various protocols such as cifs / nfs / ftp / http Share files with users. [0003] However, in the prior art, it is impossible to protect some data that needs to be archived; it is impossible to ensure that the data in the protected file will not be modified or deleted. This is the weak point of prior art. [0004] Therefore, aiming at the above-mentioned defects in the prior art, it is very necessary to provide a method and system for protecting and archiving data in a distributed file storage...
