John Morehouse has a Powershell script to estimate how much disk space you’re using with backups:
Recently, I needed to be able to determine the total size for all the most recent full backups for certain servers. Luckily for me these particular servers were using Ola Hallengren’s Maintenance Solution which simplified things since each back up had it’s own specific directory. Powershell has the flexibility to easily provide what I need with little effort.
Let’s take a look!!
John shows specifically the latest full backup, but you can extend this to include other sets as well.
