robocopy /MIR keeps copying NEWER

[umayxa3]

We have a NAS that users are allowed to store extra data to.
I am doing backups of my PST files to my network share using:
>robocopy <source> <destination> /MIR

EVERY time I run this, even if there is no change in the files, it sees
the source as being NEWER and copies the files over.

I'll assume this is because our NAS is strange (long story). The NAS
may have a time difference or not allowing perameters copied that
tells "newer".

To work around this, I want to ONLY COPY if the file sizes are
different.

I can't seem to figure this out. How do I tell robocopy to ONLY COPY if
the file sizes between source and destination are different?

Thanks,

Are the drives a mixture of FAT and NTFS?

Have you tried adding /FFT

[umayxa3]

That's the ticket!

Works perfect using /MIR /FFT

Thanks!

I spoke too soon :(
It doesn't work when copying across the network. It still shows the
local files as being NEWER. Even if I run once and again right
afterwards, it copies all the data.

I only want to copy if: FILE SIZE IS NOT EQUAL

Any suggestions how to make this happend?

Thanks,

I think I found my answer:

~=~=~=~=~=~=~=~=~=~=~=~=~
@echo off
if NOT %~z1 == %~z2 ( echo DO NOTHING ) ELSE ( echo DO ROBOCOPY )
~=~=~=~=~=~=~=~=~=~=~=~=~
I'll obviously change the "echo" to my Robocopy script.

I then call it like this:
>docopy.bat C:\my_local_pst_file.pst L:\my_remote_pst_file.pst

If they have the same file size, do nothing. If they are different,
kick off the Robocopy script.

I'll be testing this at work today and follow up if this doesn't work.

From memory XXcopy can do that - it seems Robocopy does not have that
feature.  http://www.xxcopy.com

Your batch syntax will only work if you can create a list of exclude files
that Robocopy can handle.  I don't know Robocopy well enough but I don't
think a simple text file list is enough for it.

Hi All,

 

This is my first email in this group. even though i got lots of usefull resources from this group, but recently getting into the batch files.

at the moment i need a script that can print to a local printer and as well to a network printer that has ipp protocol.

 

Any help would be greatly appreciated

 

Thanks

Hello Omer.Try something on the lines of:
type PrintMe.txt >> prn
Where you need to print the entire contents of the file directly. However,
if you wish to print something like the rendered html file, this will not
work (it is expected to print the html source instead).

Just to let you know you have encountered a defect in your nas product, Windows OS from 2000 on employ a time stamp with a 64 bit value, some samba based NAS devices run an older samba code base that can return a 32 bit or 64 bit timestamp depending on the smb call done.

Robocopy and the windows host are expecting a 64 bit timestamp and your NAS device returned a 32 bit value.

If you have support on this device I would open a ticket with your vendor as they have a defect in their product causing you needless pain.
