The invention provides a
cloud computing-based safety
backup system and method. The safety
backup system comprises a cloud terminal, a cloud
backup center, and a
data center, wherein the cloud terminal is configured on local
information processing equipment and is used for executing file backup
recovery operation, generating backup file snapshot, extracting file information, inquiring and downloading files and recording operation information; the cloud backup center is used for managing the cloud terminal, setting backup
recovery strategy information, managing backup data and managing backup file operation
authorization; and the
data center is used for storing the file information, the file snapshot, the backup
file storage information and the
authorization information. Compared with the prior art, the
cloud computing-based safety backup
system and method have the advantages of improving the file backup, inquiry and
recovery efficiency of massive data based on the
cloud computing and improving the
file management safety and reliability by uploading the backup files, the file snapshot and the calculated MD5 values of the files, have a rapid previewing function, can realize rapid file downloading and recovery and can solve the problem of coverage of files with same name.
