Backup system, recovery system and method based on container sandbox

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...

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 at the system level each time, and the backup is only for the current version of the system. After the basic system is replaced, the system backup is incompatible. It will cause two problems: (1) For example, the system is backed up three times. The first backup is A, the second backup is B, and the third backup is C. In fact, C contains the modification of B, and B contains The modification of A will cause the backup file to become larger and larger. If it is not cleaned up in time, the backup speed will be slower as time goes on; (2) It can only do incremental backup of the whole system, and cannot perform specific modules or layers of the system make a backup
