Arq (Cloud Backup for Mac) Adds Support for Amazon Glacier


November 6th, 2012

Back Up to Amazon Glacier

Arq now backs up to Amazon’s new Glacier service, and I’m really excited about it! Glacier storage is super-cheap — just $.01/GB per month!

With Glacier you can store 100GB for just $1/month! Or store a terabyte for just $10/month!

I got hundreds of emails and tweets asking for Glacier support. Turns out it’s a good option for some scenarios (even with the slow restore time and┬ápossible extra Amazon charges). People want to use it for big stuff like iPhoto libraries, videos, etc that get too expensive in S3. They use it as a┬ásecondary backup, so they don’t expect to actually restore unless their whole house burns down, taking their primary backup with it.

Arq’s been getting pretty popular with independent folks as well as corporate employees. One user described it recently as “the backup utility of choice for the geekier segment of the Mac community.” Glacier support makes Arq a good fit for even more people!

Retrieval Costs

Amazon has designed Glacier for “infrequent retrievals”, according to their FAQ. In the event you need to restore a significant amount of data from Glacier, Amazon may charge you an additional retrieval fee on top of the standard data-transfer-out charges. The formula for calculating this retrieval fee is complicated, but Arq helps figure it out for you. When you select an item to restore, Arq shows you the expected retrieval fee given the detected download rate:

You can adjust the download rate to change the retrieval fee:
