Robocopy Modified Date Problem

[HermanMunster]

Hi,

Since I updated to 11.3-U1 the robocopy script I run to sync an UNRAID server to my FreeNAS server always copies the new files, where previously It would have ignored the files once copied. On investigation I noticed that the copied files on the FreeNAS server had the modified date of *now* rather than the modified date of the UNRAID server, hence the files always re-copy. I've been running the Robocopy script for years without problem:

robocopy "z:\folder1" "\\freenas\folder1" /e /copy:dt /r:0 /w:0 /ndl /mir

Reverting back to 11.3-RELEASE fixed the problem.

Is there anything I can do about this issue?

Thanks

Herman

I use the below script for just copies the new files and changed files and it works fine

@echo off

:: ie, it just copies the new files and changed files.

this script if you like coding and scripts, also there are GUI alternatives to robocopy that can do this job without any problems or consuming much time in coding, peer sync , gs richcopy360 and securecopy quest as an example.

I've had similar problems, but I assumed it was because I'm migrating the backups from a different system to FreeNAS and hadn't updated the times yet. I'm hoping I've covered it now everything is back in sync.

Have you tried running robocopy with the /timfix option once? This might set the correct times, so that you can go back to normal afterwards.

Also, just BTW and AFAIK: /mir implies /e, so you don't really need that extra option.

Another thing I just realised looking at the documentation (here) is that there is a /COPY: option as well as /DCOPY option which is for directories. For directories, the default is DA(data, attributes) and not Time. I'm going to go add that to my scripts :)

Had the same issue and must revert to 11.3 too ... this problem fix is expected in 11.3-U2

 

[tonci]

This was not only robocopy issue , but pure copy/paste drag&drop resulted the same ... original timestamp was never preserved ... 11.3 is handlong this correctly

 

[HermanMunster]

Thanks for the replys. You've given me a few options.

I have also noticed this problem in 11.3-U1 when doing a copy using the File Explorer. Date Modified is set to the date of the copy. I am pretty sure this was working in 11.3.

I couldn't find a Jira ticket covering the issue, but I just found a related thread, where @anodos from iXsystems says the problem will be fixed in 11.3-U2. There is also a patch mentioned early in the thread. (I think I read somewhere that 11.3-U2 is due at the end of March.)

for me, I prefer GUI SWs
