The Amazon S3 Glacier storage classes are purpose-built for data archiving, providing a low cost archive storage in the cloud. According to AWS, S3 Glacier storage classes provide virtually unlimited scalability and are designed for 99.999999999% (11 nines) of data durability, and they provide fast access to archive data and low cost.
We only compared the costs but as most of our machines and services are AWS centric and final call was with client so they decided to go with AWS Glacier only.
Amazon Glacier isn't a direct competitor to the products I've listed; it could compare to the clouds/data warehouses each of these products use to store their data. In the case of CloudBerry, Amazon Glacier is used with it to create a complete archival backup system. That …
Glacier is convenient with systems already on AWS and cheaper than S3 for data that needs to be accessed infrequently. A great tool for any team to use that has a legacy system or data.
Since the rest of our infrastructure is in Amazon AWS, coding for sending data to Glacier just makes sense. The others are great as well, for their specific needs and uses, but having *another* third-party software to manage, be billed for, and learn/utilize can be costly in …
The other alternatives for us would involve moving objects out of S3 to some other object storage services, which would generate a lot of network traffic, or keep the objects on more expensive storage.
It is significantly cheaper than other services, however, it is because it actually is a slightly different service. The other services we've tried allow live reading/writing of data as needed, whereas Glacier is a "cold storage" service. So essentially your choice ends up …
As described in the use case, it is perfect for backup data storage where you do not expect to retrieve the data often. Think of it as a data dump; it is nice to know you have a backup, but it actually is expensive and somewhat difficult to retrieve everything.
Amazon Glacier isn't a direct competitor to the products I've listed; it could compare to the clouds/data warehouses each of these products use to store their data. In the case of CloudBerry, Amazon Glacier is used with it to create a complete archival backup system. That said, when using Amazon Glacier along with a product like CloudBerry, you can create a reliable, inexpensive cloud backup system for retaining HUGE quantities of data for much less than these other cloud backup solutions. HOWEVER, if you want to restore said data, the cost and complexity begin to become a major concern, so Amazon Glacier should only be considered in situations where you don't plan to touch the data regularly, if at all, once it's at Glacier.
