I noticed my system was backing up a lot. Checked Time Machine and it had backups almost every hour and the setting screen says backing up every hour for next 24 hours.

I see no option to stop this and it's set to delete old backups when it runs out of space, yet I don't see how many are being deleted.

The problem is that if I need to go back to an older one, I'm stuck with only hourly new ones.

Version 10.8.2

The only option I see is to select disks/files or to turn it off.

I certainly don't need hourly backups, even daily is a bit much but ok.

My concern is also some kind of malware that would cause this in an effort to spread itself to all my backups.

Q. where do you change the hourly backup or is it an option?

That's how it is suppose to work. It backs up hourly, then daily, then weekly as it needs to. It's only backing up the changes, it is not like it does a full back up of every file every time.

From Apple's Web Site:

Time Machine keeps hourly backups for the past 24 hours, daily backups for the past month, and weekly backups. The oldest backups are deleted when your backup drive becomes full.

Yes, that is how it is designed to work. You could always eject the backup drive if you want to stop it.

Time Machine should notify you when it runs out of space, before it starts deleting any of your old backups.

Time Machine scans your computer hourly for any new or changed files. If there aren't any, it doesn't actually back anything up.

Ok, thanks!

I might have to buy a larger HD for backups. I took a 4T USB and split it up, so I'll have to go in and check how I split it up. Maybe an extra large backup spot would be best.

Strange that I never noticed this before :D

It only backs up what has changed. If you've done nothing, it backs up nothing. If you've created a 5Mb text file, it backs up a 5Mb text file, nothing more.

Try this:

Works well for me.

And BTW: you won't need "to buy a larger HD for backups" - TM automatically deletes old backups once the disk get nearly full. Whatever disk you use will eventually fill up with TM's content, and you don't need to touch it at all.

TM will just keep the recent stuff, and progressively less-frequent copies of old stuff.

Just a suggestion:

Have you considered trying either CarbonCopyCloner or SuperDuper for backups?

Both are free to download and try.

It's a completely different paradigm than Time Machine. TM's operational motto seems to be "turn me on, I'll do the rest."

With CCC or SD, it's up to YOU to create a backup, and what you get will be a completely bootable clone that looks EXACTLY like your source drive.

If you find TM frustrating in its behavior, and you don't like the gigabytes and gigabytes of disk space that it eats up creating one copy after another after another after another after another after another (had enough?) of files you'll never need to access, try a cloning/backup app.

You may be pleasantly surprised.
