Schedule backups of your AD LDS instance using Dsdbutil [2]

In my last post, I provided a small batch file to support scheduled IFM dumps of an AD LDS instance.  Afterwards, I realised that batch files are sooo last century and decided to have a crack at the Powershell version.  I’m no Bwandon, but the script below seems to do the trick.

# Run Dsdbutil.exe to create the IFM dump file Invoke-expression $DumpIFM# Rename the dump file to give the backup a unique name
