Embodiment 1
[0042] figure 1 It is the process flow of the backup protection method for defending ransomware file data according to Embodiment 1 of the present invention Figure 1 .
[0043] Such as figure 1 As shown, a backup protection method for file data against ransomware, including:
[0044] Step S100, receiving an operation request on a file.
[0045] Specifically, the file here may also include a folder, and the operation request on the file includes but not limited to the following operation requests: operations such as reading, writing, renaming, deleting, and creating on the file.
[0046] Step S102, determining whether the size of the file is smaller than a preset upper limit.
[0047] Specifically, the preset upper limit value can be adjusted by the user according to the actual situation, and the present invention does not limit the specific size of the preset upper limit value.
[0048] Step S104, if the size of the file is smaller than the preset upper limit, determine ...
Embodiment 2
[0095] figure 2 It is the backup protection system structure for defending ransomware file data according to Embodiment 2 of the present invention Figure 1 .
[0096] According to the above method, the present invention also proposes as image 3 A backup protection system for file data against ransomware, including:
[0097] The receiving module is configured to receive an operation request on a file.
[0098] The first determining module is configured to determine whether the size of the file is smaller than a preset upper limit.
[0099] The second determination module is configured to determine whether the file belongs to a preset file backup type when the size of the file is smaller than a preset upper limit.
[0100] The processing module is configured to perform an operation request on the file after backing up the file in the storage medium if the file belongs to the preset file backup type; directly execute the operation request on the file if the file does not b...
