Leopard duplicate disk failure

[marhk]

Under 10.4 I had an auto duplicate operation set up that worked well to provide an alternate bootable disk. After upgrade to 10.5.1 duplicate won’t work because of Time Machine issues.

 

Log = {Can't write file “.com.apple.timemachine.supported”, error -42 (too many files open), path: “Christine/.com.apple.timemachine.supported”. Trouble writing files, error -42 (too many files open).}

 

OK, that has been explained before - but, how do I exclude this file during a duplication procedure? File selection doesn’t work during a duplication process and, unless things have changed recently, I have never been able to achieve a bootable disk using an archive and restore procedure (too involved anyway - duplication is what I need).

 

What is needed is a selector under the OPTIONS button to exclude Time Machine files during a duplication operation.

 

What am I missing?

Well, what, exactly, are you doing?

 

- What is your Source?

- What is your Destination?

- How have you configured the Time Machine preference pane?

Sure it does. Selectors are available for Duplicate operations the same as they are for Backup.

Thanks for the reply!

 

You are so right! My mistake. There obviously is a way to select/exclude a file by name (i.e.; .com.apple.timemachine.supported) I did this and so far a duplication process manually started seems to be going OK.

 

What I’m doing is simply duplicating one internal hard disk to another in a PPC machine. Time Machine is active on the main drive to an external firewire drive.

It seems unlikely to me that a single small configuration file (/.com.apple.timemachine.supported) would be stopping Retrospect's Duplicate operation.

 

Instead, I'd think that the very act of Time Machine running _at the same time_ that you're trying to duplicate one volume to another could result in more open files then OS X can support.

 

But tests are the key; if your Duplicate is consistently successful, do let the Forum readers know.

Interestingly, it worked - done once in manual mode. Down the road - we'll see? Before I excluded this file (on all backups not just duplications of Leopard) it would fail.

 

Some other features are that it seems to take 50% longer vs. 10.4.10 for a duplication.

Upon starting up from the duplicated drive all went well. The fascinating thing to me is at first trying to decide which disk it actually started from. The right upper corner is no longer respected in Leopard for the startup drive.

Time Machine works as expected. Upon opening the Time Machine, all of the old backups of the source drive are there and available. (I have the duplicated drive excluded from TM in the source disk TM prefs) So, these TM files of the source drive can be used if I ever have to jump to the duplicated backup drive.

 

Sounds too simple - I agree - but, so far it works.

 

I still think there should be a simple button in the backup choices of Retrospect to choose this, however. (More Leopard friendly. ;-)

How does the speed compare when you turn Time Machine off?

I shall have to try that at some point.
