Abstract:
1. A method implemented in a non-transitory computer-readable storage medium as executable instructions that process on one or more processors to perform the method, comprising: exposing, by the processors, a list of the files having changes in a file system as an independent Virtual File System (VFS) that is used to perform a backup operation on the list of files that changed, the VFS used as a single addressable interface that bridges different file systems, wherein exposing further includes detecting event notifications at a kernel level of the OS for each of the changes, wherein detecting further includes using a File System in User Space (FUSE) module to track the event notifications from the kernel level; and acquire, by the processors, metadata by querying inodes for the files, the metadata including data changes of each file and an increase or decrease in file size for each file after the changes.
