[0002] With the rapid development of information technology, the importance of data has become increasingly prominent. Both individual users and corporate organizations face the risk of data loss, damage or tampering. Therefore, data backup has become one of the important means to ensure data security. Traditional data backup methods are often full disk backups, that is, each backup will copy the entire data set, which is not only time-consuming and labor-intensive, but also wastes a lot of storage space.
[0003] With the advancement of technology, log-based incremental data backup technology has emerged. This technology can capture data changes in real time or periodically and only back up the changed parts, thereby greatly improving backup efficiency and saving storage space. However, existing log-based incremental data backup devices often have fixed structures and cannot be folded or stretched. They are not easy to carry and move, and cannot flexibly expand backup capacity. In view of this, we propose a log-based incremental data backup device. Utility Model Content

[0026] As a preferred embodiment of the present invention, a first support plate 2 is provided above the topmost placement plate 1, a first cushion block 20 is fixedly installed between the first support plate 2 and the topmost placement plate 1, and a positioning structure for limiting the placement plate 1 is fixedly installed at each of the four corners of the first support plate 2. The positioning structure can limit the placement plate 1 that is not in use, preventing the hard disk rack from being fully unfolded, thereby increasing flexibility during use.
[0027] As a preferred embodiment of the present invention, the positioning structure includes a lower extension plate 4 fixedly connected to the first support plate 2, each lower extension plate 4 is provided with a limiting shaft 41 for limiting the placement plate 1, and the lower extension plate 4 is provided with a plurality of mounting holes 40 which are arranged at equal intervals and are used to cooperate with the limiting shaft 41. When the hard disk rack is fully folded, the mounting hole 40 is aligned with the through hole 14 provided on the outer wall of the placement plate 1, and the limiting shaft 41 is threadedly connected to the mounting hole 40 and plugged into the through hole 14.
