To get the Job:
1) Education: You need Certs, MCSE. VM ware is a good on too as many orgs are consolidating and visualizing, and some sort of backup system. The certs are so that the prospective employer knows you are not BSing. A degree doesn't hurt.
2: You need experience. Because good employers know that you can get certs and not actually know anything on how to do the job.
3: People/sales skills. Because you need to make the connection and sale yourself to actually land the job.
To do the job:
1: You need the ability to learn and adapt because the real world is nothing like school. New tech is always coming out and you need to be able to adapt.
2: You need to know how to program/script. Because working smarter and not harder is the only way to stay ahead of all the work.
3: People skills again. "Plays well with others" is always a good thing.
And ad Mr. Anthony said. Backup Backup Backup. Have a disaster recovery plan and test it 2-4 times per year. Recover a file from your backups at least once per month if not once per week.
