My first powershell script – move and delete SQL backup files

Remember my first Sony? I had a walkman and it was the first electronic device I took apart and put back together when I was around 11 years old. After that it was held together by some masking tape but I managed to at least get it back together and it could still play tapes. Well, I managed to create my first powershell script by deconstructing other scripts I found and doing some basic tutorials. My script just moves SQL bak files with “full” in the name from a backup folder to an archive folder then cleans up the archive folder. For testing I have it in that order, but in production you’ll want to clean the archive folder first.

The first thing I needed to do was move some files based on date. Moving files is really easy, moving them based on date not so much. But I managed to find a script that I deconstructed and tailored to what I needed. After getting the files to move I realized it would move ALL files, not just my full backups. It took me a couple hours to find, but it’s actually just a simple -filter switch. The final step was to make sure the archive folder only had one set of backups in it. That one was a lot simpler and just involved one line, which I added to so I could create some variables. Below is the final product.
