1. A computer-implemented system comprising:
a processor; and
a memory storing a plurality of executable instructions that, when executed by the processor, cause the system to:
identify modified folders during an incremental backup scan;
receive an input comprising a modification time limit from a user;
generate a filetype database comprising a list of filetypes in each folder of a plurality of folders of a storage;
generate a file modification database comprising a list of filetypes modified and a corresponding latest modification time for each of the modified filetypes;
check, at one or more times of the incremental backup scan, whether each folder of the plurality of folders of the storage contains a filetype listed in the file modification database,
after a filetype is checked as being listed in the file modification database, compare a latest modification time thereof to the modification time limit,
identify one or more folders as a modified folder(s) if the latest modification time is less than the modification time limit; and
scan the identified folder during the incremental backup scan.
