Zip From server..

[yuppicide]

We have a bunch of servers running Win XP in our office. I'm the one who does the backup of our database and then after that I must .zip it up to save space. We keep backups of the past two weeks as well as tape backups.

Anyway, our computers are older/slower. I have a 1.8Ghz CPU with 1GB ram, but zipping stuff still takes up my precious resources and slows down my system. I normally don't run anything to intense outside of GiMP graphic editor.

My question: Is there a program I can put on our server (without having access to install stuff on the server), such as a command line zip type program or whatever, in which I can start the zip and then close the dos prompt and it'll keep doing it?
