将整个过程状态存储在磁盘上并在以后还原? (在Linux/Unix上) [英] Storing entire process state on disk and restoring it later? (On Linux/Unix)

问题描述

我想知道:是否可以使用系统调用，库，内核模块或命令行工具将正在运行的程序的 complete 状态存储在磁盘上?

I would like to know: Is there a system call, library, kernel module or command line tool I can use to store the complete state of a running program on the disk?

也就是:我想将当前正在使用的进程的内存，页面布局，堆栈，寄存器，线程和文件描述符完全转储到硬盘驱动器上的文件，并能够稍后无缝地将其还原，就像模拟器"savestate"或虚拟机快照".

That is: I would like to completely dump the memory, page layout, stack, registers, threads and file descriptors a process is currently using to a file on the hard drive and be able to restore it later seamlessly, just like an emulator "savestate" or a Virtual Machine "snapshot".

如果可能的话，我还希望有多个程序状态的备份副本"，所以如果程序由于某种原因死了，我可以恢复到上一个​​执行点.

I would also like, if possible, to have multiple "backup copies" of the program state, so I can revert to a previous execution point if the program dies for some reason.

这可能吗?
