Also for clarification is the move placeholder Utility still limited to subfolders of the share, so if you have 100 sub folders of a home dir you would have to run it for each?
Correct
does the move placeholder aspect of FSAUtility move everything archived like doing a restore of the placeholders?
It is a copy/delete operation. So if you have the following:-
Archive Point is at the share level so you would have an archive called share1
\\server1\share1\folder1 - 10 items archived in this folder
\\server1\share1\folder2 - 10 items archived in this folder
So currently you would have 20 items in archive named share1
If you then had with an archive point at share2:-
\\server2\share2\folder1
You would then run fsautility -m -s
\\server1\share1\folder1 -d
\\server2\share2\folder1
If you were to copy the items for example with explorer to your other server this would generate a recall of the files on the source server and then you would have the original file on your destination server and they would be archived again on the next run in the new archive.
What this will do is copy/delete (move)10 items
So now you would have 10 items in the archive named share1 and 10 items in archive named share2
Lastly what would happen if you turned off the placeholder service and moved the placeholders?
If you mean when using FSAUTILITY then the operaion would not work as the placeholder service is used.
Using Robocopy like you have done does copy the files directly and they will open fine but when you come to archive them again it will try and archive them where they now are again in the new archive which is your case it cannot find as you must have not set it up.
Hope all of that makes sense
