version 0.2
<#
.Description
Current Features:
1. Check for any errors on the Sources or Destinations and generate a report of any extra spaces in UNC
2. Scan for any open files from the source directory recursively and generate a report of any locked files during the copying operations
3. Execute robocopy to mirror each source to its corresponding destination with a time stamp variance allowance of 2 seconds for speed and resiliency
Features under development:
4. Turn on Volume Shadow Copy (VSS) at source
5. Remote into each source machine to perform file copying operations
6. Copy from VSS snapshots rather than from live systems to capture locked files
Recommendations:
1. Execute in the context of a Domain Administrator
2. Run this script on the source server to eliminate extra hops
