I keep seeing these "[W043] Error Setting Times" messages in my backups. What's causing this and what do they mean?

Information about [W043] error messages

During a BRU backup, if you encounter messages that state "[W043] Error Setting Times" followed by another message, such as "Permission denied," then you can relax.

These messages are warnings from BRU to you.  BRU is simply letting you know that it's backed up the file, however, when BRU attempted to modify the access time (atime ) or the modify time (mtime ) of the file specified, it encountered the the error that follows the message.  The error occurs when BRU executes a system call utime (update time).

Common associated errors that you may see are:

  • Permission Denied - BRU was denied the permissions required to make the system call utime.  Make sure that BRU is running as the Root user (Unix, Linux, Mac OS X ) or Administrator (Windows). See commands below how making sure that BRU Server Server and BRU Server Agent are running as Root.
    • Resolution: See the steps below.
  • Invalid argument - An error occurred while processing the utime system call, thus preventing the atime and mtimes from being updated.
    • Resolution: In most cases, the error encountered is not something that you'll be able to change.  You should contact TOLIS Group Support for additional assistance.
  • Mac OS X Only: The file has been locked in the "Get Info" windows within Finder.
    • Resolution: Remove the check next to the "Locked" option in Finder.

There may be other Unix error messages associated with this, these above are just the most commonly seen.

Make sure BRU Server is Running as Root

To make sure that BRU Server is running as Root, run these commands on any Linux/Unix system:

Warning: This will abort any currently running backup jobs for BRU Server.  Make sure there are no backups running before starting these steps.

sudo /usr/local/bru-server/server --kill

This should result with something like:

$ sudo /usr/local/bru-server/server --kill
Sending signal to 2478

The number specified there references the process ID number for BRU Server.  This number is always changing so it's normal to a different number as a result on your system.

Next, you'll need to wait at least two minutes on Mac OS X system before starting the BRU Server daemon. The reason for this is because Apple programed Mac OS X to not allow a port to become free and another process to bind to that port for 120 seconds.

Once two minutes has passed, run:

$ sudo /usr/local/bru-server/server

You should see something like:

$ sudo /usr/local/bru-server/server

That will start the BRU Server daemon as the Root user and ensure that the problems you're seeing are not because of BRU Server not running as Root.

If BRU Server is set to start automatically, that means when the system boots up, the process is started as Root.
