I created a bucket just to test the archiving in AWS Glacier using S3. I added a rule using the Lifecycle rules to Permanently Delete 3 days after the object's creation date and I applied this rule to the whole bucket.
Now after 3 days, the test bucket is empty as it should be but I don't know how to access my archived bucket in Glacier using S3. I searched on the AWS documentation and came across this link but how can I restore an object if the bucket is empty, kindly help me to restore the bucket from AWS Glacier.
How did you setup your life-cycle rule?
If you set it to glacier after 1 day and permanently delete after 3 days then it is GONE.
Gone from your bucket after 1 day = put Item is in Glacier. remove from bucket.
You could restore it from glacier at this time.
Permanent Delete after 3 days = delete from glacier. file does not exist in glacier or bucket

Change your 'Action on Objects' to Archive and then Permanently Delete
and set the glacier day to 3 and your permanently delete date to a long time from now (365 days). At 365 days your object will be removed from glacier.

I have 50TB of data in an S3 Standard bucket.
I want to transition objects that are greater than 100MB & older than 30 days to AWS Glacier using an S3 Lifecycle Policy.
How can I only transition objects that are greater than 100MB in size?
There is no way to transition items based on file size.
As the name suggests, S3 Lifecycle policies allow you to specify transition actions based on object lifetime - not file size - to move items from the S3 Standard storage class to S3 Glacier.
Now, a really inefficient & costly way that may be suggested would be to schedule a Lambda to check the S3 bucket daily, see if anything is 30 days old & then "move" items to Glacier.
However, the Glacier API does not allow you to move items from S3 Standard to Glacier unless it is through a lifecycle policy.
This means you will need to download the S3 object and then re-upload the item again to Glacier.
I would still advise having a Lambda running daily to check the file size of items, however, create another folder (key) called archive for example. If there are any items older than 30 days & greater than 100MB, copy the item from the current folder to the archive folder and then delete the original item.
Set a 0-day life-cycle policy, filtered on the prefix of the other folder (archive), which then transitions the items to Glacier ASAP.
This way, you will be able to transfer items larger than 100MB after 30 days, without paying higher per-request charges associated with uploading items to Glacier, which may even cost you more than the savings you were aiming for in the first place.
To later transition the object(s) back from Glacier to S3 Standard, use the RestoreObject API (or SDK equivalent) to restore it back into the original folder. Then finally, delete the object from Glacier using a DELETE request to the archive URL.
create a lambda that runs every day (cron job) that checks for files older than 30 days and greater then 100mb in the bucket. You can use the s3 api and glacier api.
In the "Lifecycle rule configuration" there is (from Nov 23, 2021 - see References 1.) a "Object size" form field on which you can specify both the minimum and the maximum object size.
For the sake of completeness, by default Amazon S3 does not transition objects that are smaller than 128 KB for the following transitions:
From the S3 Standard or S3 Standard-IA storage classes to S3 Intelligent-Tiering or S3 Glacier Instant Retrieval.
From the S3 Standard storage class to S3 Standard-IA or S3 One Zone-IA

I have a lifecycle policy setup in the AWS Console. In my S3 bucket, it has a folder called "backups". My policy has a prefix of "backups" and current and previous transition to glacier set to 1 day after creation. S3 files are still shown as Standard and nothing in Glacier.
I have waited a month to see if it was slow. But nothing happens.
To test this, I did the following:
Created a new Amazon S3 bucket
Created a backups folder through the S3 management console
Uploaded a file to the backups folder
Added a Lifecycle Rule with a filter of backups (displayed in the console as "prefix backups" for current version to Glacier after 1 day
I then waited a couple of days and it transitioned to Glacier:
Bottom line: It can take a couple of days for the transition to happen.
Thanks for reading this.
I am able to transfer files from S3 to Glacier after 30 days using lifecycle rule. However, how do I make the same files get deleted from Glacier after 3 months?
Thanks.
If the objects were moved from S3 to Glacier via a Lifecycle Policy, add a permanently delete setting to the lifecycle policy to Delete the objects after n days. This will delete the objects from both S3 and Glacier.
If, instead, the objects were uploaded directly to Glacier, then there is no auto-deletion capability.
As far as I'm aware, Glacier does not currently have lifecycle policies for Glacier vaults like it does for S3.
You could create your own autodelete setup (likely within the not-expiring-after-12-months AWS Free Tier) by writing metadata about the Glacier archives to DynamoDB (vault name, archive id, timestamp) and have a scheduled Lambda function that looks for archives older than 30 days and deletes them from Glacier and DynamoDB.
It's a bit of work to set up, but it would accomplish what you're trying to do.
I have created a lifecycle policy for one of my buckets as below:
Name and scope
Name MoveToGlacierAndDeleteAfterSixMonths
Scope Whole bucket
Transitions
For previous versions of objects Transition to Amazon Glacier after 1 days
Expiration Permanently delete after 360 days
Clean up incomplete multipart uploads after 7 days
I would like to get answer for the following questions:
When would the data be deleted from s3 as per this policy ?
Do i have to do anything on the glacier end inorder to move my s3 bucket to glacier ?
My s3 bucket is 6 years old and all the versions of the bucket are even older. But i am not able to see any data in the glacier console though my transition policy is set to move to glacier after 1 day from the creation of the data. Please explain this behavior.
Does this policy affect only new files which will be added to the bucket post lifepolicy creation or does this affect all the files in s3 bucket ?
Please answer these questions.
When would the data be deleted from s3 as per this policy ?
Never, for current versions. A lifecycle policy to transition objects to Glacier doesn't delete the data from S3 -- it migrates it out of S3 primary storage and over into Glacier storage -- but it technically remains an S3 object.
Think of it as S3 having its own Glacier account and storing data in that separate account on your behalf. You will not see these objects in the Glacier console -- they will remain in the S3 console, but if you examine an object that has transitioned, is storage class will change from whatever it was, e.g. STANDARD and will instead say GLACIER.
Do i have to do anything on the glacier end inorder to move my s3 bucket to glacier ?
No, you don't. As mentioned above, it isn't "your" Glacier account that will store the objects. On your AWS bill, the charges will appear under S3, but labeled as Glacier, and the price will be the same as the published pricing for Glacier.
My s3 bucket is 6 years old and all the versions of the bucket are even older. But i am not able to see any data in the glacier console though my transition policy is set to move to glacier after 1 day from the creation of the data. Please explain this behavior.
Two parts: first, check the object storage class displayed in the console or with aws s3api list-objects --output=text. See if you don't see some GLACIER-class objects. Second, it's a background process. It won't happen immediately but you should see things changing within 24 to 48 hours of creating the policy. If you have logging enabled on your bucket, I believe the transition events will also be logged.
Does this policy affect only new files which will be added to the bucket post lifepolicy creation or does this affect all the files in s3 bucket ?
This affects all objects in the bucket.
I have an S3 bucket on which I've configured a Lifecycle policy which says to archive all objects in the bucket after 1 day(s) (since I want to keep the files in there temporarily but if there are no issues then it is fine to archive them and not have to pay for the S3 storage)
However I have noticed there are some files in that bucket that were created in February ..
So .. am I right in thinking that if you select 'Archive' as the lifecycle option, that means "copy-to-glacier-and-then-delete-from-S3"? In which case this issue of the files left from February would be a fault - since they haven't been?
Only I saw there is another option - 'Archive and then Delete' - but I assume that means "copy-to-glacier-and-then-delete-from-glacier" - which I don't want.
Has anyone else had issues with S3 -> Glacier?
What you describe sounds normal. Check the storage class of the objects.
The correct way to understand the S3/Glacier integration is the S3 is the "customer" of Glacier -- not you -- and Glacier is a back-end storage provider for S3. Your relationship is still with S3 (if you go into Glacier in the console, your stuff isn't visible there, if S3 put it in Glacier).
When S3 archives an object to Glacier, the object is still logically "in" the bucket and is still an S3 object, and visible in the S3 console, but can't be downloaded from S3 because S3 has migrated it to a different backing store.
The difference you should see in the console is that objects will have A "storage class" of Glacier instead of the usual Standard or Reduced Redundancy. They don't disappear from there.
To access the object later, you ask S3 to initiate a restore from Glacier, which S3 does... but the object is still in Glacier at that point, with S3 holding a temporary copy, which it will again purge after some number of days.
Note that your attempt at saving may be a little bit off target if you do not intend to keep these files for 3 months, because any time you delete an object from Glacier, you are billed for the remainder of the three months, if that object has been in Glacier for a shorter time than that.
