Deleting a cloud tier

Before deleting a cloud tier, review the details below:

  • Data in the cloud bucket has to be deleted manually.
  • Cloud policy settings on the source containers are unaffected.

Configuring an Archive Tier

Archive tiers can be configured via the UI or via the cloud_tier command in the QoreStor CLI. Before configuring an archive tier, ensure the following requirements are met:

  • Your cloud storage must be configured prior to configuring an archive tier.
  • Archive tier is not supported when QoreStor is installed in Cloud Optimized mode, Object Direct Small mode, or Demo mode.
  • Permissions for your cloud storage must be correctly configured. Refer to Required permissions to restore from Archive Tier for more information.
  • Only RDA, VTL, and Object containers can be configured to tier data to Archive Tier.

NOTE: QoreStor's archive tier functionality relies on Amazon S3 Glacier and/or Amazon S3 Glacier Deep Archive storage. Before configuring an archive tier, your cloud archive storage must be properly configured. Please refer to the Amazon S3 documents below for more information:

Required permissions to restore from Archive Tier

In order for Qorestor to be able to perform batch operations for restoring objects to Amazon S3 storage from Amazon S3 Glacier or Amazon S3 Glacier Deep Archive storage , you must configure an AWS IAM policy with the required permissions listed below and attach the policy to your AWS account used to access the for accessing AWS S3 storage.

In order for QoreStor to be able to perform batch operations on your S3 storage, you must configure an S3 IAM role with the required permissions and batch operation policy and use that role when creating your archive tier. The permissions required are:

  • Create Job
  • Pass Role
  • The permissions defined in the "Initiate S3 Glacier restore" policy described in the Amazon S3 document Granting permissions for Amazon S3 Batch Operations
    • s3:RestoreObject
    • s3:GetObject
    • s3:GetObjectVersion
    • s3:GetBucketLocation
    • s3:PutObject
    • s3:GetBucketLocation

NOTE: Permission verification is done when restoring an object from S3.
