Data Usage Has Quadrupled since upgrading to Mavericks!

Mate.
I thought it's me who is experiencing this only.
I have a 64 GB SSD.

After a while I start to see GBs dissapearing from free space for no reason.
I did clean installs, I tried beta versions, still the same.

Some data seems to be gone.
I downloaded iWork update and iMovie update today and now I see a drop in 2 GB per total.
I assume some code was added to the apps. However 2 GB seems a lot.

I had 26 GB free 1 month ago. I installed NOTHING and freespace dropped at 18.
Then I make the update and I have now 15.6 GB free.

I have Trim Enabled.
No clue what is going wrong.

 

Time Machine local backups ?

If you are unsure that Activity Monitor is recording everything, you can try using nettop in a Terminal. Once its running, hit c to collapse the connection details to a per-process summary. Leave it running and it will log all network activity.

 

One thing to check is iCloud--especially photo streams to iPhoto.

 

Time Machine local backups are stored locally on your computer. You can disable local backups. For an SSD that small, I'd say it's pretty critical that you do.

 

This is an issue for me as well. We have satellite internet through Dish Network (DishNet/ Hughes Net... horrible, story for another time.) and thus are capped at a measly 15GB per month. I came from having Comcast with no cap so I need this thing to stop using bandwidth whenever it wants.

I was informed about updates in the App Store yesterday, so I opened App Store to see what they were. I knew I wasn't going to download them over the internet here at home and would venture to town to tether to my phone. (Unlimited LTE on Sprint)

What I didn't know was that just by merely opening App Store, it would begin downloading the updates. I HAVE AUTOMATIC DOWNLOADS/ UPDATES TURNED OFF! It was downloading in the background and did not show status bars for downloading these updates to iWork suite.

I have now turned off the only 'on' feature relating to updates- the option to even notify me of updates. I am scared to even open the App Store now because it seems like it will want to start downloading something in the background.

I really wouldn't care at all if I didn't have this completely crummy and money grab of an ISP, but I live in the middle of nowhere and it literally is the only option for Internet.

 

another possibility

ocspd process using bandwidth
"Turning off CRL & OCSP checking in the Certificates Preferences in Keychain Access solved the problem."

This solution fixes the problem...go for it. I posted about that about a month ago.

 

And it will introduce a new problem: it won't check if a certificate is still valid or not. You will be susceptible to thing we've seen with the DigiNotar hack. Their root certificate got compromised and was used for malicious websites. It was used to spy on the Iranians by their own regime in order to track down people who were against the regime. Since the certificates where seen as valid by browsers such as Safari no alarm bells went off. The DigiNotar certificate was revoked when they discovered this. A revoked root certificate will cause alarm bells to go off (it will trigger a warning about the certificate of a website). However, the browser or OS (as in this case) needs to check if a certificate is revoked or not. If you turn of the OCSP settings it won't do these checks and thus will not be able to detect a revoked certificate and warn you about it. This leaves you vulnerable to attacks.

People who live in regimes like the one in Iran are better off moving back to Mountain Lion than disabling the OCSP settings.

In this case it is very crucial to understand what you are disabling!

 

Thanks. I will try.

After you disable them is it possible to clean them?

 

I've just discovered this affects me today as well. Have knackered the certs so hopefully that fixes it.
