ABSTRACT:
A computer database system has one or more application buffers to use in performing input/output (I/O) operations. A file system receives contents of the application buffers. Contents of the file system are written into a nonvolatile memory. A backup command directed at the file system is received. A data contents of the one or more application buffers is moved to the file system in response to receiving the backup command, and the data contents are written to the nonvolatile memory. An operating system blocks I/O operations directed to the file system after the data contents of the one or more application buffers are moved to the file system. A snapshot of the nonvolatile memory is generated while the I/O operations directed to the file system are blocked.
