Is there a method to have rsync write only errors to a log file?

  • 772

I have a situation where I need to (almost)completely copy my Ubuntu HD to an external HD. The biggest problem I and encountering is that there are an extremely large number of files that won't copy for various reasons.

If I could get rsync to write only the errors it encounters to a log file, then I could use that file to create bash file to get me further along. By errors I mean any situation where a file won't copy, regardless of reason.

When I use the log option the log file is too large as it contains info on every file. So large I am unable to even open it.

rsync  /source/ /dest/ --log-file=error.log

When I tried the quiet option outputing the screen to a file, the log file I get is empty.

rsync -q /source/ /dest/ > error.log

Is there anyway to get rsync to write to a file, only the errors it has encountered?

rsync

    rsync writes error in stderr therefore error.log is empty in the following case 

    rsync -q /source/ /dest/ > error.log
    Instead of the above run the following command 
    rsync -q <options> /source/ /dest/ 2> error.log

    Now all the errors will be saved on error.log.
