Question
Robocopy taking forever to run
Hello,
We are using microsoft's Robocopy software to copy and sync files between 2 servers. The data size of the source is 160Gb. We ran a first robocopy to copy everything from the source to the target server.
I wanted to schedule the script to run every 15 minutes to copy only modified files from the source to the target, this way we would have the newest files every 15 minutes.
The problem is that the script takes forever to run when running every 15 minutes, it takes a long time to start verifying the status of files and then it seems to be very slow to verify those modified.
Is there anything wrong with the script? Can it be improved to run faster?

Haven't worked with richcopy, but the main issue is probably just the amount of files, unless these files are mostly rather large.
You can try if robocopy's /MOT:m switch helps.
Instead of running the command every 15 minutes, run it once, and add
/MOT:15
to the command line. robocopy will then *not* stop running, it will monitor the source and run again after 15 minutes if it detects any changes.
You can add a /TEE as well, that way you can monitor the output directly as well as having it in the log file.
Any expert with RichCopy experience can help?
This script is working properly, except the logging part, it does not log anything, but otherwise it seems to running and ending successfully.
"C:\Program Files\Microsoft Rich Tools\RichCopy 4.0\richcopy.exe" "E:\Partage\Publique" "\\192.168.99.14\e$\DATA\S
But the same script with a lager portion of files does not work. Would there be a reason to why it does not work with 160gb, but it works with 80gb?
I was able to get the command to create a log file, the problem was tue columns, richcopy does not use columns in its commands. Now the problem seems different, everytime I start the script, richcopy crashes.
Here's the error from the event log: Faulting application RichCopy.exe, version 4.0.217.0, faulting module ntdll.dll, version 5.2.3790.3959, fault address 0x0002caa2.
Hanging application RichCopy.exe, version 4.0.217.0, hang module hungapp, version 0.0.0.0, hang address 0x00000000.
I get that everytime I run the scrip.
Would you like to try this batch file?.....

Get rid of the /V (why do you need to log about a 160GB worth of skipped files?), robocopy is probably more busy logging than copying.
Use /NFL and /NDL instead; even with /nfl and /ndl, errors will still be logged, but you won't have your log file filling up with entries of successfully copied files.
