NAS backup to HDD after reinitialization

Hi All,
I am mirroring my NAS to a HDD using SyncBackSE and had no issues. I rebuilt the NAS RAID and copied the backup from the HDD to the NAS using FileZilla. Same folder names, etc. For a test I then ran the SyncBack profie. It compared the newly FTP copied files on the NAS to the backup HDD and wants to replace all the files in the backup. I believe attributes may be part of the issue. Any thoughts or suggestions?
