USB drives formatted with exFAT solve a host of problems compared to with NTFS. (Especially getting around ACL needless frustration just moving around one’s own BackUp from Lap to PC.)
However, good-ole RoboCopy does not like the format and always does a complete replacement vs a Purge. Apparently there is a difference in the date/time stamps wherein everything is seen as “newer” and therefor; changed.
RichCopy gets around this, but I don’t really trust it as having used RoboCopy in server back-up applications for years with many customers.
Mostly I create Robocopy batch files to run from the scheduler, which once debugged, are bullet-proof. Richcopy seems to have some problems in this regard.
Any thoughts from other IT pros?
