SL: Time Machine backups too frequently?

[cmaier]

I have a mid-2007 MBP 17" that I upgraded to SL. I've noticed that time machine seems to go every 20-25 minutes or so, instead of every hour. I checked the .plist in launchdaemons, and it's set to 3600 seconds.

Anyone else seen anything like that? (I could be crazy, but it also seems that my screen is shutting off too fast, but I haven't timed it so I might be imagining it).

Do you have backups for every 20-25 minutes, or are you just basing this off of hearing disk activity?

Backups. I use an infrant nas, and time machine launches a backup every 20-25 minutes.
