different creation date/time


Recommended Posts

I'm using Retrospect Express 7.05.102 that came bundled with a SimpleTech 250gb NAS that I connect to through my LAN.


I am trying to duplicate some picture folders to my backupdrive, (the SimpleTech NAS) Almost all goes fine except it keeps trying to copy "Thumbs.db" files and then complains it can't find them. Below is an example of some of the entries from the log.



File "C:\Documents and Settings\Fred\My Documents\My Pictures\2006-03-01\Thumbs.db": can't write, error -1101 (file/directory not found)

File "C:\Documents and Settings\Fred\My Documents\My Pictures\2006-03-02\Thumbs.db": can't write, error -1101 (file/directory not found)

File "C:\Documents and Settings\Fred\My Documents\My Pictures\2006-03-05



This is a mere nuisance, but please read on below.


I am also getting the following log entries by the hundreds (about 10% of the total being copied). Every time the script runs it recopies hundreds of files that have already been copied instead of simply the new ones. It cites "different creation date/time" because it finds a discrepancy of 2-4 seconds This wastes lots of time running a process that needn't run. What can I do about these problems??? Help!

Everytime this error is reported for one of your files, Retrospect will duplicate the file again the next time around.


In order to avoid this you will need to change the creation date/time so that there is no discrepancy. You can do this with most photo manipulation programs. A useful, lightweight image application can be found here: http://tucows.com/preview/194967 (this app is a personal favorite). You can use this to open the file and then "save as", this should change the creation date for you.


This is a fairly common problem, many digital cameras timestamps can cause these issues when the images are transferred to a computer. There is a KB article regarding this, but I don't have a link to it handy.

Thanks for your reply. I guess I should have been more clear. The problem was only occuring when duplicating to a SimpleTech NAS-250. The problem was not encountered when I tested it by duplicating to a folder on either the source computer or my networked laptop. The problem lies with the NAS drive. They've had a previous firmware fix for a problem where the NAS operating system (a linux variant) was munging up file dates, apparently they don't have it *all* fixed. Curious was that most of the errors were showing time differences of 2-4 seconds but that was enough to trigger the error and the software would want to re-copy the same files at the next run. I'm using this to back up some camera files and I just couldn't get used to it wanting to redo 12-15 gigabytes over and over and over and over.... I returned the NAS drive (again, but this time for good) and replaced it with a Western Digital USB drive and everything works as it should. It was very frustating considering that the Retrospect came bundled with the drive! However I like Retrospect so much, I bought the full 7.5 version.



Thanks again
