Ok.. direct from the expert!

Sorry for the frustration.  I think there’s a different way for TY20 you want to go about doing what you’re doing.

First, let’s fix your Issue. To clean up the duplicates on Computer 2:

• Locate the restored files (probably in the data directory).
• Ensure that the backup folder from computer 1 is not in the data directory anywhere.
• Rename the homebase folder in prowin20 directory to “homebase_backup”
• Start ProSeries and run HomeBase Maintenance.
• Next, delete the backup folder from computer 1 so you don't accidentally work on these files.

Going forward, to copy files from computer 1 to computer 2:

On Computer 1

• In HomeBase, select your files, right click, and choose “Copy/Backup” 

On Computer 2

• Copy the backed up files from computer 1 into the data directory of computer 2. Be sure to overwrite existing files if updating clients (rather than putting them in a subfolder), or there will be duplicates again.
• Run HomeBase Maintenance.

Hopefully that makes sense and gets you pointed in the right directory. If not I'll see if I can get you on a call with the experts to work things out.
