Scanning only new files via cron

Hi All
I am experiencing really high resource usage when using the following command

files:scan --all

I tried using --unscanned but this doesn’t seem to fit my needs.

If there a way to do files:scan without scanning every single file? i.e. only scanning the new files on the disk?

The only thing who i found is this:

sudo -u www-data php occ files:scan --help
   files:scan [options] [--] [<user_id>]...

   user_id                Will rescan all files of the given user(s)

       --output[=OUTPUT]  Output format (plain, json or json_pretty, default is plain) [default: "plain"]
   -p, --path=PATH        Limit rescan to this path, eg. --path="/alice/files/Music", the user_id is determined by the path and the user_id parameter and --all are ignored
   -g, --groups=GROUPS    Scan user(s) under the group(s). This option can be used as --groups=foo,bar to scan groups foo and bar
   -q, --quiet            Do not output any message
       --all              Will rescan all files of all known users
       --repair           Will repair detached filecache entries (slow)
       --unscanned        Only scan files which are marked as not fully scanned
   -h, --help             Display this help message
   -V, --version          Display this application version
       --ansi             Force ANSI output
       --no-ansi          Disable ANSI output
   -n, --no-interaction   Do not ask any interactive question
       --no-warnings      Skip global warnings, show command output only
   -v|vv|vvv, --verbose   Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug

but why you make this manually, it should work automatical.
