Amazon S3 Glacier is a cloud service dedicated to storing archived data that is not likely to be retrieved often. In other words, it is designed for infrequently accessed data. Glacier has a high latency of data retrieval but offers low pricing and high safety for stored archives. In this article, we are going to explain Glacier’s data uploading nuances. Working with S3 GlacierAmazon Glacier is a quite cost-effective solution for the prolonged keeping of important data that is not used often. It is a nice choice for a company that possesses a lot of outdated electronic documentation and wants cheap but safe storage. Amazon does not urge its customers to store more or less there, though Glacier's optimal usage model foresees archives to be kept for a longer period of time. FREE WHITEPAPER Archiving to the Cloud: Cold Storage How to use cold storage - like Amazon S3 Glacier - cost-effectively and efficiently? Find out in our whitepaper:  Glacier storage ensures high redundancy, as an archive is stored within multiple facilities at once. The archived data is secured with AES-256 encryption on the server-side. Additional safety is ensured by Vault Lock policies. The monthly storage price is fixed and varies from $0.004 to $0.013 per 1GB, depending on the region. Retrieval is free for up to 10 GB a month. The deletion of data is free if this data was stored for more than 3 months, otherwise, an early deletion fee would be applied. Further reading Amazon S3 Glacier Pricing Explained
Users have to set up jobs in order to download archives or archive lists in vault snapshots. These jobs run in the background and usually take several hours to complete. There are two ways to upload data
Let's explore both of them in detail. There is no Wizard in the AWS console for uploading archives to Glacier vaults. Users have to do that by creating requests via Glacier REST API or use AWS Software Development Kits (or SDKs) for their own applications. All that requires some coding and AWS provides SDKs with Glacier support for the following programming languages:
This way of uploading is, therefore, most convenient for users with programming skills or for third-party providers who offer their own tools for S3 Glacier storage management. Amazon provides two alternative schemes of direct upload to Glacier:
Single operation option is available for up to 4GB of data. Upload in parts is recommended for archives bigger than 100MB: it transfers each part in a parallel session (size of parts is specified by the user). If a session fails, only this part would be missing so a user will have to resend only it alone. No additional fees are charged for multipart upload. Scheduled Upload to Glacier from S3Data that is already in AWS’s cloud can be moved to Glacier storage with the help of the lifecycle policy feature. If you do not urgently need some of the files stored in an S3 bucket, it is possible to schedule their transfer to a less costly place - that is what these policies are for. You can create a policy via your AWS console, in the Properties page of your S3 bucket. Just make sure that the Archive to the S3 Glacier Storage Class checkbox is selected. After a new policy is created, your data will be transferred from S3 to Glacier after the time specified. It will not show up in Glacier storage, however - you still could view it from the S3 bucket. You would have to restore this archive from Glacier before any other operations would be available. Further reading How to Upload Files to S3 Glacier with Lifecycle Rules Scheduled upload to Glacier is the best option in case the user's data is already in S3. It is also a more convenient way for companies with a great flow of electronic documentation because it allows an administrator to automate the archiving of a large number of items. On the downside, this additional tier of storage results in extra storage fees plus a request fee for archiving to Glacier. SummaryBoth ways of transferring data to Glacier storage have certain pros and cons. Let us summarize their differences to make the comparison easier.
MSP360 Backup supports Amazon Glacier and you can perform direct uploads of the data to your Glacier storage. It's also possible to create and manage lifecycle policies and transfer archives to Glacier directly from the MSP360 Backup user interface.

Which of the following is not correct about Amazon Glacier?2. Optimized for data for which retrieval times of several hours are suitable. This is untrue about Amazon glacier, as it provides a very rapid data recovery.
Which type of data is not suitable to be stored in Glacier?Thus, Glacier storage is not suitable for storing active data that is changed frequently. A base unit of storage in Glacier is called an Archive. An archive can represent a single file or several files can be combined and uploaded as a single archive.
Can you upload directly to Glacier deep archive?The easiest way to store data in S3 Glacier Deep Archive is to use the S3 PUT API to upload data directly. You can also upload data to S3 Glacier Deep Archive over the internet or using AWS Direct Connect and the AWS Management Console, AWS Storage Gateway, AWS Command Line Interface, or the AWS SDKs.
What must be configured for data archiving to Glacier?How to set up archive to Amazon Glacier. Go to your Amazon S3 buckets and select a particular bucket:. Click Management:. There is no lifecycle rule applied to this bucket. ... . Enter a rule name and choose a rule scope:. Configure expiration (the number of days from object creation):. Review configuration settings:. |
