title: Is there a less costly option than gsutil rsync for backup to cloud storage?
body: <p>We are currently utilizing the new coldline storage to backup files off site, the storage part is super cost effective. We are using gsutil rsync once a day to make sure our coldline storage is up to date. </p>
  
  <p>The problem is that using gsutil rsync creates a massive number of class A requests, which are quite expensive. In this case it would be at least 5x the amount of the coldline storage making it no longer a good deal. </p>
  
  <p>Are we going to have to custom code a custom solution to avoid these charges, is there a better option for this type of back, or is there some way get rsync to not generate so many requests?</p>
