TH72698A - Providing a file system subset of the transient status - Google Patents

Abstract

DC60 (12/05/46) System, methods and computer-readable media for provisioning the file system subset momentary state. The first momentary state of the first set of source files in the file system is created. The first momentary state includes the corresponding innode for each source file in the first set of files. Stored in each innode are the first identifier associated with the first set of files and the second identifier associated with the time of the first momentary state. Subsequently, the second momentary state of the second set of source files is executed. The second momentary state includes the corresponding innode for each source file in the second set of files. Stored in each innode are the first and second identifiers. Subsequent momentary states are executed at every first and every second period for the first and second sets of files, respectively. System, methods and computer-readable media for provisioning the file system subset momentary state. The first momentary state of the first set of source files in the file system is created. The first transient state section includes the corresponding innode for each source file in the first set of files. Stored in each innode are the first identifier associated with the first set of files and the second identifier associated with the time of the first transient state section. Subsequently, the second transient state section of the second set of source files is acted upon. The second transient state section includes the corresponding innode for each source file in the second set of files. Stored in each innode are the first and second identifiers. Subsequent transient states are acted upon at every first and every second period for the first and second sets of files, respectively.
