1. A method for performing pre-backup tasks, comprising:
obtaining, by a proxy host, a snapshot request associated with an incremental backup of a file system stored in a network attached storage (NAS) from a backup manager;
in response to obtaining the snapshot request:
instantiating a NAS container to obtain a snapshot of the file system;
providing the snapshot to the NAS container;
after providing the snapshot to the NAS container:
retrieving a previously generated slice list and backup metadata associated with the file system;
identifying, using the backup metadata and the slice list, data types associated with each of the slices;
grouping the slices based on the data types and group criteria to generate slice groups;
generating an updated slice list specifying the slices and the slice groups; and
providing the updated slice list to the backup manager.
