This invention provides a method for mutual backup of operating system partitions on a single RAID solid-state drive (SSD) and the SSD itself, relating to the field of storage backup technology. This invention enables SSD manufacturers to implement SSD backup of the operating system disk through specific functions developed in the firmware. Before leaving the factory, the SSD is configured with two partitions of equal size: a visible primary partition for operating system installation and a secondary partition as a hidden operating system backup partition. The user installs the operating system on the primary partition, along with necessary drivers and applications. A command is triggered by continuously powering on and off n times. When the SSD detects that it has been powered on n times consecutively within a predetermined time period, the SSD firmware is triggered to completely back up the visible partition to the hidden secondary partition. When the device enters idle mode, newly added data on the visible system disk partition is automatically backed up to the hidden secondary partition. When the operating system on the primary visible partition is corrupted and cannot function properly, the system is powered on and off m times consecutively. If the SSD detects that it has been powered on and off m times within a specified time period, the SSD's firmware is triggered to switch the device to the operating system on the backup hidden secondary partition. The secondary partition becomes the primary visible operating system partition, and the primary partition becomes the hidden backup secondary partition. After confirming that the new primary visible partition successfully boots the system, the system is powered off. An unbackup operating system operation is then performed, achieving mutual backup of the operating systems.

The application discloses a cluster operation and maintenance method and device, electronic equipment and a storage medium, relates to the computer technical field, and the method is applied to a management node in a cluster, and comprises the following steps: constructing operation and maintenance components of at least one operating system through at least one first virtual machine; wherein the operation and maintenance components comprise an in-memory operating system image file; the in-memory operating system image file comprises an operation and maintenance execution tool; based on a pre-boot execution environment service program, guiding an execution node in the cluster to load corresponding operation and maintenance components, so that the execution node executes operation and maintenance operations through the operation and maintenance execution tool based on the completed in-memory operating system. Compared with operation and maintenance operations executed through a hard disk operating system, the in-memory operating system has the characteristic that system operations are restored after restarting, damage of viruses and malicious software to the operating system is avoided, operation and maintenance safety of the cluster is improved, and operation and maintenance efficiency of the cluster is improved.
