This seems simple.
I performed a Test Restore from an external HDD for a single user to an internal HDD on one of our servers. The restore was successful for 138,000 files in 3,100 folders for a total of 42GB but...
There were a handful of folders (perhaps 5-6) that the restore failed for claiming...
"Access is Denied".
The restore was done "retaining permissions". I checked the destination folder and it was indeed empty but the permissions were the same as folders above it that did restore successfully (permissions were inherited). Further, the account the restore was run from had administrator rights.
Any idea of why this would be a problem considering the above details? I suppose I could have tried a restore ignoring the current permissions but I wanted to test both the restoration and retention of original permissions.
