Storage system snapshots for continuous file protection

A method for providing continuous data protection, the method comprising:

• trapping a file system call;
• evaluating if the trapped file system call is associated with a file that has been modified;
• generating a storage snapshot in response to the file having been modified;
• determining if a previous storage snapshot has been rendered redundant by generating the storage snapshot,
• wherein determining that the previous storage snapshot has been rendered redundant comprises identifying that a version of a file protected by the previous storage snapshot is also protected by generating the storage snapshot.

A computer storage medium having computer-executable instructions stored thereon which, when executed by a computer system, cause the computer system to:

• trap a file system call;
• evaluate if the trapped file system call is associated with a file that has been modified;
• generate a storage snapshot in response to the file having been modified;
• determine if a previous storage snapshot has been rendered redundant by generating the storage snapshot;
• and
• causing the computer system to delete the previous storage snapshot if the previous storage snapshot has been rendered redundant.
