Slicer library for high-density file system
The NAS agent creates slices of the NAS share for backing up a folder that contains a huge number of files (more than one million). Eight slices are backed up in a single session and the maximum allowable sessions for each NAS proxy is three.
The slicing agent within the NAS agent crawls and creates metadata of the files and shares. During the backup process, the backup agent uses this metadata to backup the files rather than initiating the second crawl process to read the files in the folder.
The slicing and chunking of files within the NAS shares reduces the overall backup time, and allows backup of high-density folders and folders that have huge number of files without any subdirectories.
