Problems solved by technology

In this case, it is difficult to guarantee the absolute security of key systems in the network, so it is necessary to adopt backup and recovery technology to ensure that data can be recovered as soon as possible in case of accidental data loss, and the loss of users can be minimized
[0005] The inventors of the present disclosure found that most of the existing system backup and recovery methods are slow, and cannot achieve backup accuracy, real-time performance, and self-defined backup; because the system backup is based on what modifications are made on the basic system, In the prior art, these modifications are backed up, that is, incremental backups are made a

Example Embodiment

[0049] Example 1:

[0050] Such as figure 1 As shown, Embodiment 1 of the present disclosure provides a backup system based on a container sandbox. The entire system adopts a four-layer architecture: including a kernel driver layer, a customized desktop layer, a data storage layer, and an application center layer.

[0051] The system is started up in layers based on containers; the system is just a few packaged files (basic system files and kernel); after the system is started, the basic system files will be loaded as the bottom container sandbox; the operations performed by the user on the started system will not be performed Persistence, that is, resume after restart.

[0052] The user can perform persistent operations on the started system (using built-in commands), and the system will automatically solidify the user's modifications to generate a new layer of container. The new container layer modified by the user and the basic file will be started the next time the user starts i...

Example Embodiment

[0070] Example 2:

[0071] Embodiment 2 of the present disclosure provides a system backup method based on container sandbox, such as image 3 Shown.

[0072] Suppose the system disk is the first SCSI disk, the device name is / dev / sda[1,2,3,4,5,6,7], the system also has a data scsi disk, the device name is / dev / sdb1, and the file The system is ext3.

[0073] The user can back up the system to the specified device with one key:

[0074] S41: Boot the CD, and boot to Shell state according to the linux rescue mode;

[0075] S42: Mount the data disk for backup;

[0076] S43: Backup system;

[0077] S44: Pop up the light zone and restart the system.

[0078] In step S43, it also includes the steps of backing up the container and the container backup:

[0079] S431: First, in order to back up the container, you can first check the list of containers to be backed up.

[0080] S432: After finding the container to be backed up, create a snapshot of the container. This step will generate a container ...

Example Embodiment

[0086] Example 3:

[0087] Embodiment 3 of the present disclosure provides a system recovery system based on a container sandbox, which includes a memory in which a backed-up container sandbox is stored;

[0088] The container sandbox includes at least a kernel driver layer, a customized desktop layer, a data storage layer, and an application layer;

[0089] The kernel driver layer is configured to drive and be compatible with various hardware devices, the customized desktop layer is configured to customize the image user interface of the operating system; the data storage layer divides the storage area for the protection of the operating system , Is configured to store different types of data; the application layer is configured to provide system software management services;

[0090] The system starts hierarchically based on the container sandbox. After the system is started, the basic system file is loaded as the bottom container sandbox; by performing persistent operations on the ...

Abstract

The invention provides a backup system, recovery system and method based on a container sandbox, belongs to the field of linux system development and application, and the invention comprises a kerneldriving layer, a customized desktop layer, a data storage layer and an application center layer which are arranged in the container sandbox. The system is started in a layered mode based on a container sandbox, and after the system is started, a basic system file is loaded as a bottom-layer container sandbox; persistence operation is executed on the started system, and the system automatically solidifies the modification command to generate a new container layer; the basic file and the modified new container layer are started in the next starting process; system backup is realized by integrally backing up a container sandbox to external equipment, and the external equipment carrying the container sandbox for system backup is used for recovering a system to a specified position; rapid system backup and recovery are realized, and the safety of the system is ensured.

Description

technical field [0001] The present disclosure relates to the field of development and application of linux systems, in particular to a container sandbox-based backup system, recovery system and method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] While an application cannot crash a normal modern operating system, it can wreak havoc on the operating environment of the operating system. From the perspective of resource utilization, how to limit the resources that a process or a group of processes can use is also an urgent problem to be solved. So people came up with the concept of sandbox (Sandbox), which isolates an application or a group of applications in a restricted environment so that it cannot escape. For a sandbox, it is a process rather than a thread. However, Linux schedules threads by default instead of scheduling processes...
