DB Backup Script Broken - Archive Question

I am using the newest ELA 5 on windows server 2003. I am trying to get my backup strategy going and there are lots of posts that mention the backup scripts. there is one in the ela\troubleshooting directory and one in the ela\tools directory. neither work for me. I have shutdown ela and try running both and I get an error in the middle of the process that says file now found.

Now to my archive question. in the ELA\archive folder there is a folder for every host I am monitoring, and it also looks like a zip is created for every host every 7 days. is what is being archived there still in the DB? and if so would it be better for my disk space to make it archive in larger intervals so I don't have double data (same data archived and in DB)
