Method and system for providing storage checkpointing to a group of independent computer applications

A non-transitory computer readable medium storing a plurality of computer executable instructions for execution by a processor, the computer executable instructions for:

• taking a storage checkpoint for at least one of at least one full checkpoint and at least one incremental checkpoint for one or more applications in an application group;
• wherein the at one or more applications are comprised of one or more processes, and each process comprised of one or more threads;
• wherein intercepted file operations are added to a file operations data structure upon entering said file operations interceptors, intercepted file operations are removed from said file operations data structure upon completion of said file operations;
• and
• wherein checkpointing of user-space pages is comprised of write-protecting one or more user-space memory pages and including said one or more user-space memory pages in a checkpoint.

A system, comprising:

• a storage disk structured to store files;
• a storage access interface structured to access the files stored on the storage disk;
• and
• a processor structured to process instructions that:
• take a storage checkpoint for at least one of at least one full checkpoint and at least one incremental checkpoint for one or more applications in an application group;
• wherein the one or more applications are comprised of one or more processes, and each process comprised of one or more threads;
• wherein intercepted file operations are added to a file operations data structure when said file operations interceptors are entered, intercepted file operations are removed from said file operations data structure upon completion of said file operations;
• and
• wherein checkpointing of user-space pages is comprised of write-protecting one or more user-space memory pages and including said one or more user-space memory pages in a checkpoint.
