Abstract
Provided are a method, system, and article of manufacture for system recovery. An operating system and a backup copy of the operating system are both maintained in a partition of a computational device. A boot loader receives an indication to load the backup copy of the operating system. The boot loader loads the backup copy of the operating system. The computational device is rebooted with the loaded backup copy of the operating system.
Claims30
A method, comprising:
- maintaining, in a partition of a computational device, both an operating system and a backup copy of the operating system;
- receiving, by a boot loader, an indication to load the backup copy of the operating system;
- loading, by the boot loader, the backup copy of the operating system;
- and
- rebooting the computational device with the loaded backup copy of the operating system.
A system, comprising:
- memory;
- a partition coupled to the memory;
- and
- circuitry coupled to the memory, wherein the circuitry is capable of:
- (i) maintaining both an operating system and a backup copy of the operating system in the partition;
- (ii) receiving, by a boot loader, an indication to load the backup copy of the operating system;
- (iii) loading, by the boot loader, the backup copy of the operating system;
- and
- (iv) rebooting the system with the loaded backup copy of the operating system.
An article of manufacture, wherein the article of manufacture is capable of causing operations in a computational device having a boot loader, the operations comprising:
- maintaining, in a partition of the computational device, both an operating system and a backup copy of the operating system;
- receiving, by the boot loader, an indication to load the backup copy of the operating system;
- loading, by the boot loader, the backup copy of the operating system;
- and
- rebooting the computational device with the loaded backup copy of the operating system.
