Web Interface and Daily Backup

[MxxCon]

if you have a capable enough mobile device, you could probably use some service like LogMeIn which is web-based remote desktop.
alternatively you can install windows version of ssh server and then connect to it and kill whatever processes you want to.
or see if you can configure your ftp server to run at lower/idle priority so that during high load other tasks won't get slowed down by the ftp transfers.
