FIG. 2 is a block diagram of an apparatus for protecting disk data according to the present invention.
Detailed Description
To make the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
Fig. 1 is a flowchart of a method for protecting disk data according to the present invention, as shown in fig. 1, in a BIOS environment, including:
step 100, a partition for data backup is established in a Basic Input Output System (BIOS) environment.
It should be noted that, in the BIOS environment, establishing partitions for data backup is a routine technique for those skilled in the art.
Step 101, writing data to be backed up in the established partition for data backup when data backup is performed; when data recovery is performed, data for recovery is read from the partition in which backup data is written.
It should be noted that, in the BIOS environment, it is also common knowledge of those skilled in the art that data to be backed up can be displayed and written into the data to be backed up. The method can realize effective protection of the disk data, and is based on data backup in the BIOS safety environment, when an operating system during work of a user is started, the backup data in the BIOS environment cannot be displayed, and the safety requirement of the backup data is the safety requirement of the BIOS environment, so that the safety of data backup is higher.
The method of the invention also comprises the following steps: after the partition for data backup is established, a restore key for starting the data backup is set.
The data backup operation is simple and easy to use by setting the recovery key, for a user, the operation processes of data backup and data backup in the same hard disk are basically the same when the user enters a BIOS environment, the setting of the recovery key is to set the key for entering the data backup or recovery when the user starts up, in order to avoid conflict, the keys which are already set to be in a safe mode, a BIOS mode and the like and have set attributes are eliminated, and other single or combined keys can be used for setting the recovery key.
