Amazon Glacier and Arq 3 combined allow for off-site computer backup solution. In November I posted about my first impressions backing up with Amazon Glacier client Arq 3 . Nearly 2 months in it seems like a good time for an update of my continuing thoughts on this off-site data backup solution. You can read more about the service and my initial setup of the software in my previous post off-site backup with Amazon Glacier .
Glacier is just like it sounds: S-L-O-W. The process of uploading my initial complete backup is still in process and has been for 50 days, almost continuously. There are of course lots of factors including my household internet upload speed. And it is a lot of data, 165GB to date according to Arq. Although I could have simply pointed Arq at my hard drive to back it all up, I chose to pick and choose what I thought was most critical and incrementally add to my backup. Based on the time it has taken I strongly recommend this approach - get the important data backed up first!
Testing your backup is critical. I initiated a file restoration of a backed up 6MB file, which Arq reported I could expect the file to be delivered in 4 hrs. The file arrived as promised within minutes of the 4 hours.
Glacier being slow cannot be fairly considered a criticism as it is advertised as exactly that: Glacier. What Amazon is offering is low cost data storage. To date I have spent less than $10 in fees, the majority being upload transfer charges. For instance for the month of December while populating my backup:
||$0.81 ($0.010 per GB / month)
||$3.83 ($0.050 per 1,000 requests)
All-in-all I am very happy with the Arq 3 and Amazon Glacier redundant catastrophic backup solution. I'll continue to run Time Machine as a quick access local backup.
If you missed it I encourage you to read my first post, off-site backup with Amazon Glacier , where you will find my initial impressions during setup and the first few days with Arq 3 .

New Arq 3 Taps Amazon Glacier for Backup Nirvana

It's hard to think of a cheaper, better way to create and store an offsite backup of your files. Back when Glacier first launched we speculated that it would be a perfect fit for a backup utility like the OS X backup app Arq.
