Robocopy weirdness

Question

I have been running the following command to copy files every morning at 01:00 over the VPN to a system offsite for disaster recovery reasons:

robocopy.exe "\SERVER\Share" "E:\Share" /COPYALL /SECFIX /E /XO /R:1 /W:1 /nfl /ndl /LOG+:"C:\Temp\companyshare.log"

The log it produces always looks like this:

-------------------------------------------------------------------------------

Indicating it copied over some amount (eg:141.921g) of files and was successful.

But for some reason over the last 2 weeks I get this every night:

-------------------------------------------------------------------------------

    Files : *.*
	    
  Options : *.* /NDL /NFL /S /E /COPYALL /SECFIX /XO /R:1 /W:1

Giving no indication that files were copied. If examine the destination location I do find that, in fact, files were copied.

If I run the same .bat file manually (not in Task Schedular) it runs fine and gives me the first kind of output.

I have been running this every morning at 01:00 for years now, nothing has changed (other then system updates). It runs on the receiving machine. Both machines are Server 2012 Standard.

Because it works fine manually, it makes it hard to debug. Any ideas how I could do that?

Answer 1

Ok, might try delete / recreate the task. The task user may have somehow lost access to \SERVER\Share\

Answer 2

So is E:\ a local disk or a mapped drive?
