Question

I am running a robocopy job through a batch file that is scheduled to run every hour. I am using the following switches:

Robocopy \servername\share D:\somedir /E /R:5 /Log+:D:\Logs\CopyLog.txt

It has been working faithfully for a long time but it ran into a snag this morning. I went to check the log file and was suprised to find it had grown to just shy of 280 Mb.

My question then is how I can change my batchfile to write more managable log files? I think it would make sense to append on a period for which it is reported in. ie: CopyLog_201103.txt would be the log file for March 2011.

I’m fairly adept at working with higher level programming languages, but command line programming was already long gone by the time I was growing up. I’m definitely learning the value of getting a firm understanding of the much more basic computer concepts.

Any suggestions/advice would be appreciated, thanks in advance.

Answer 1

You can get the day, month and year using this cmd snippet:

for /f "usebackq tokens=1-3 delims=/" %%d in ('%date%') do (
    set day=%%d
    set month=%%e
    set year=%%f
)

(Warning: locale specific.)

Now you can write to different log files as you see fit.
