Please check out cvdupdate or Freshclam for your updates. Once or twice a day to check is fine.

FWIW, running cvdupdate only once or twice a day is a BAD idea.

If you are running a private mirror, then if Freshclam tries to get the latest CDIFF (according to DNS) from the private mirror ...

My understanding is that if you're using a private mirror you're supposed
to set the 'PrivateMirror' option, which does not use DNS to check for the
existence of updated files, but checks the files themselves directly.

Quoting 'man freshclam.conf':

    PrivateMirror STR
        This option allows you to easily point freshclam to private
        mirrors. If PrivateMirror is set, freshclam does not attempt
        to use DNS to determine whether its databases are out-of-date,
        instead it will use the If-Modified-Since request or directly
        check the headers of the remote database files.  For each
        database, freshclam first attempts to download the CLD file.
        If that fails, it tries to download the CVD file.  This option
        overrides DatabaseMirror, DNSDatabaseInfo and ScriptedUpdates.
        It can be used multiple times to provide fall-back mirrors.
        Default: disabled
