Patent ID: 8762341

Claim:
A non-transitory, computer-accessible storage medium storing program instructions executable by one or more processors to: for each respective backup policy of a plurality of backup policies, configure the respective backup policy with information specifying a respective subset of a plurality of files to be backed up; in response to changes to the plurality of files, maintain a global file change log that lists which files of the plurality of files have been changed; process the global file change log, wherein in processing the global file change log, the program instructions are executable to: for each respective backup policy of the plurality of backup policies, determine which particular files of the respective subset of files corresponding to the respective backup policy are listed in the global file change log, and add the particular files to a respective policy-specific file change log for the respective backup policy; and clear the global file change log; wherein the program instructions are further executable by the one or more processors to perform a respective backup operation for each respective backup policy, wherein in performing the respective backup operation for each respective backup policy, the program instructions are executable by the one or more processors to backup the files listed in the respective policy-specific file change log for the respective backup policy; wherein after performing the respective backup operation for each respective backup policy, the program instructions are further executable by the one or more processors to clear the respective policy-specific file change log for the respective backup policy.
