Time Machine backups causes Final Cut Pro to grind to a halt...

[Ben1l]

Has anyone else noticed that when their Mac is making a Time Machine backup, playback in FCP becomes impossible/very sluggish?

If so, anyone got any ideas about how to stop this happening other than stopping the backups?

Starting to really annoy me that my editing is interrupted once every hour.

Thanks

Time Machine is CPU intensive, so is FCP. There is no way to avoid a slowdown in FCP if TM is running other than to stop the backup.

istat shows hardly any CPU usage when TM backups are happening. Next to nothing in fact.

If it's not the CPU, it's the hard drive or some sort of indexing function (what does Activity Monitor say, out of curiosity?). You've seen the experimental results anyways, not really sure why you're asking an obvious question. The 1+1 of not using FCP while a TM backup is in process seems clear to me.
