Hot data is data that is accessed frequently and\/or needs to be available quickly, and cold data is unlikely to be accessed often. One example of hot data that has gone cold is a month\u2019s worth of weekly backups of your databases. Within the first 30 days of the files being created, you need them accessible to recover rapidly.. After 30 days, they are unlikely to be used but kept available to extreme circumstances.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">AWS has simplified this transition through the use of <\/span><a href=\"https:\/\/docs.aws.amazon.com\/AmazonS3\/latest\/dev\/object-lifecycle-mgmt.html\" target=\"_blank\" rel=\"noopener noreferrer\"><span style=\"font-weight: 400;\">object lifecycle policies<\/span><\/a><span style=\"font-weight: 400;\">. Object lifecycle policies allow you to specify storage transition rules along with purging settings.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In our example, you could store the initial backups in S3 Standard. You could then set an object lifecycle policy to transition each backup from S3 Standard to S3 Glacier after 30 days.

In Amazon Glacier data is stored in special containers, called vaults. That architecture was both unique and difficult to access and manage. Thus, over time, AWS has restructured its solution and created Amazon S3 Glacier, which used more user-friendly and common buckets to store data in.<br \/>\nThat allowed 3-rd party software developers <a href=\"https:\/\/www.msp360.com\/resources\/blog\/aws-s3-glacier-storage-class-instead-of-aws-s3-glacier-vaults-step-ahead\/\">to abandon vaults and use more convenient buckets in Amazon S3 Glacier<\/a>.<\/p>\n<h2><span style=\"font-weight: 400;\">Restoring Objects from Amazon S3 Glacier<\/span><\/h2>\n<p><span style=\"font-weight: 400;\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-29459 alignright\" src=\"https:\/\/www.msp360.com\/resources\/wp-content\/uploads\/2019\/03\/Restoring-Objects-from-S3-Glacier.png\" alt=\"Restoring Objects from S3 Glacier\" width=\"160\" height=\"161\" srcset=\"https:\/\/www.msp360.com\/resources\/wp-content\/uploads\/2019\/03\/Restoring-Objects-from-S3-Glacier.png 160w, https:\/\/www.msp360.com\/resources\/wp-content\/uploads\/2019\/03\/Restoring-Objects-from-S3-Glacier-150x150.png 150w\" sizes=\"auto, (max-width: 160px) 100vw, 160px\" \/><\/span><\/p>\n<p><span style=\"font-weight: 400;\">To get objects out of Amazon S3 Glacier, you need to request to restore the object. Restoring the object will pull it out of Glacier and into a standard S3 storage class where it can be accessed immediately.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">When making a restore request from Glacier, there are a few things to consider:<\/span><\/p>\n<ul>\n<li><b>Restore speed<span style=\"font-weight: 400;\">: As mentioned in the Glacier Storage Classes section above, AWS provides three options on restore speed -- expedited, standard, and bulk. The right choice for you depends on your budget and how quickly you need the data.<\/span><\/b><\/li>\n<li><strong>How long to keep the data<\/strong>:<span style=\"font-weight: 400;\"> When restoring data from Glacier, you specify an amount of time to keep the restored data in S3. This helps you to save on cost if you only need the restored data for a short period. If you need the restored data for longer, copy the restored object to a permanent location in S3.<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><span style=\"font-weight: 400;\"><span class=\"further-reading \">Further reading<\/span>\u00a0<\/span><a href=\"https:\/\/www.msp360.com\/resources\/blog\/temporary-restore-from-glacier\/\"><span style=\"font-weight: 400;\">Temporary Restore from Glacier with MSP360<\/span><\/a><\/li>\n<li><strong>Cost and AWS Free Tier<\/strong><span style=\"font-weight: 400;\">: The costs for restoring data will be affected by a few factors: the size of the data you\u2019re restoring, the restore speed you use, and the retention time you specify.<br \/>\nAWS does provide a Free Tier for S3 Glacier.<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><span style=\"font-weight: 400;\"><span class=\"further-reading \">Further reading<\/span>\u00a0<\/span><a href=\"https:\/\/www.msp360.com\/resources\/blog\/amazon-glacier-pricing-explained\/\"><span style=\"font-weight: 400;\">Amazon Glacier Pricing Explained<\/span><\/a><span style=\"font-weight: 400;\">.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">While the basic restore functionality has been a core of Amazon S3 Glacier since the beginning, AWS has been steadily adding features over time.

The new restore request must use a faster restore speed than the existing restore -- you cannot downgrade your restore speed.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">You may not change other details about your restore after it has been started, such as the number of days to retain your objects after they are restored.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Receiving S3 Glacier Restore Notifications<\/span><\/h3>\n<p><span style=\"font-weight: 400;\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-29461 alignright\" src=\"https:\/\/www.msp360.com\/resources\/wp-content\/uploads\/2019\/03\/Receiving-S3-Glacier-Restore-Notifications.png\" alt=\"Receiving S3 Glacier Restore Notifications\" width=\"160\" height=\"161\" srcset=\"https:\/\/www.msp360.com\/resources\/wp-content\/uploads\/2019\/03\/Receiving-S3-Glacier-Restore-Notifications.png 160w, https:\/\/www.msp360.com\/resources\/wp-content\/uploads\/2019\/03\/Receiving-S3-Glacier-Restore-Notifications-150x150.png 150w\" sizes=\"auto, (max-width: 160px) 100vw, 160px\" \/><\/span><\/p>\n<p><span style=\"font-weight: 400;\">One of the downsides of using Amazon S3 Glacier is that restoring an object takes a variable amount of time, and you have to constantly check whether the restore process is completed..<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In November 2018, AWS added the ability to receive <a href=\"https:\/\/docs.aws.amazon.com\/AmazonS3\/latest\/dev\/NotificationHowTo.html\" target=\"_blank\" rel=\"noopener noreferrer\">S3 event notifications<\/a> when the restore has finished. Rather than polling for the object to exist, you can receive a notification in an <a href=\"https:\/\/www.msp360.com\/resources\/blog\/aws-free-tier-sns-sqs-ses\/\">SQS queue<\/a>, an <a href=\"https:\/\/www.msp360.com\/resources\/blog\/aws-free-tier-sns-sqs-ses\/\">SNS topic<\/a>, or a Lambda function once your restore has completed.<br \/>\n<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Conclusion<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">In this post, we covered the powerful Amazon S3 Glacier service.
