How to get Robocopy to only work on folders that have recently been modified?

Question

Using Robocopy, I’m trying to copy from a source to a destination across a network. The source and desination both have thousands of folders (they're a delayed replica of each other), but I want Robocopy to only look in directories of a certain age… Let’s say, two days old.

In other words, I don’t want Robocopy to enumerate anything past the root directory if it hasn’t been modified for two days. As it stands now, Robocopy is crawling the entire directory structure of the source and destination and it is taking hours.

Answer 1

I suspect you are running Robocopy on the destination server and transferring files from a source server. This is why you are having terrible performance.

You'll get better performance by running robocopy on the source server and transferring over the network to the destination server.

Answer 2

To increase robocopy performance you can try the switches:

/MT[:n] : Multithreaded copying, n = number of threads to use (1-128), default = 8 threads
/FFT : Assume FAT File Times (2-second date/time granularity)

One of the log switches:

     /LOG:file : Output status to LOG file (overwrite existing log).
  /UNILOG:file : Output status to Unicode Log file (overwrite)
    /LOG+:file : Output status to LOG file (append to existing log).
 /UNILOG+:file : Output status to Unicode Log file (append)

/NDL : No Directory List - don’t log directory names

Not to use the /Z or /ZB switches
