How do I turn time machine off temporarily?
When I watch films from my NAS via wireless I need to turn off time machine because once it kicks in there isn't enough bandwidth for them both and the film stops and starts.
I assumed that I could go to Time Machine preferences and turn it off using the big switch - but it doesn't stop it. The icon in the menu bar goes grey, but the time machine will still do backups. A bit of internet research indicates that when it is doing this it is keeping local snapshots on the Mac's hard disk, but this is not the case for me. Today, although time machine was turned off a couple of days ago, there was the greyed out icon spinning away telling me it was backing up 4GB of 6GB. I turned wireless off and after a few minutes got the error message that time machine can't access my time capsule. A quick check with Time Machine Buddy shows that it was, indeed, backing up to my Time Capsule over WiFi. What's going on?
I didn't turn off the time machine when it was half way through a backup - I turned it off a couple of days ago. Is there a reliable way to temporarily stop time machine when I'm doing bandwidth-heavy stuff?
Thanks in advance for any help.
