Problems solved by technology

[0004] In a distributed file system, due to the large number of clients and frequent access, it is inevitable that there will be erroneous file operations, such as wrong uploads, wrong changes, or more serious wrong deletions, resulting in unexpected changes or loss of file content, resulting in unexpected Loss
In addition, file errors caused by network transmission errors are also one of the important reasons for system file insecurity.

specific Embodiment 1

[0052] A highly fault-tolerant distributed file security storage system, including: a client end, which completes operations such as consulting, modifying, deleting, and saving files; an analysis server, which completes file encryption, decryption, and path orientation; file storage.

[0053] A highly fault-tolerant distributed file security storage method based on the above-mentioned security storage system, the specific method steps are:

[0054] A. The operation log records the operations of the file server on file content changes, including upload, update, and delete operations;

[0055] B. For errors caused by accidental file changes, the user makes a recovery request, and the system rolls back the operation through the log records to correct the errors.

[0056] Correct the wrong operation or roll back the operation to avoid or reduce the loss caused by it and achieve high fault tolerance of the system.

[0057] The steps further include: after receiving the recovery r...

specific Embodiment 2

[0071] Based on the distributed file secure storage method of the secure storage system in the specific embodiment one, the specific method steps are:

[0072] 1. The operation log records the operation of the file server FileSerDel on changing the content of the file, including uploading, updating and deleting;

[0073] 2. For files deleted by users, retrieve them through operation logs and file deletion backups.

[0074] Retrieve accidentally deleted files, avoid or mitigate the losses caused by them, and achieve high fault tolerance of the system.

[0075] like image 3 As shown, the steps further include: after the parsing server receives the retrieval request from the user, after judging that the request is legal, the request is passed to the file server that previously stored the file. For example, it is necessary to determine whether there is permission for the retrieval request to avoid leakage of documents.

[0076] In this specific embodiment, the file server in s...

Abstract

The invention provides a safety storage system and a safety storage method for distributed files. The safety storage method comprises the steps of recording the operation of changing the content of files by a file server based on an OperateLog, wherein the operation comprises uploading, updating and deleting; putting forward a recovery request by a user for an error caused by accidental changing of the files, carrying out rollback operation through the recording of the OperateLog by the safety storage system, and achieving the correction on the error; finding a file which is deleted by the user through the OperateLog and file deletion backup for the files deleted by the user, and achieving the correction on the error. According to the safety storage system and the safety storage method, provided by the invention, correction or rollback operation can be carried out on error operation, the file which is accidentally deleted can be found, the loss caused by the accidental deletion of the file can be avoided or relieved, and the high error tolerance of the system can be realized.

Description

technical field [0001] The invention relates to a highly fault-tolerant distributed file security storage system and a method thereof, in particular to a highly fault-tolerant distributed file security storage system and a method suitable for Internet smart TVs. Background technique [0002] At present, Internet users are growing rapidly, and a large number of user visits is a huge test for the data throughput and system concurrency of the system platform. In the process of frequent file interaction, it is inevitable that there will be errors caused by user misoperation or network reasons. This requires the system to provide sufficient fault tolerance to correct this wrong operation or roll back the operation to avoid or mitigate its losses. [0003] Most of the existing distributed file systems focus on the high throughput of the system, and less consideration is given to the fault tolerance of the system. [0004] In a distributed file system, due to the large number of ...
