Immutability
Veeam Backup & Replication allows you to prohibit deletion of data from the extents of the scale-out backup repository by making that data temporarily immutable. It is done for increased security: immutability protects your data from loss as a result of attacks, malware activity or any other injurious actions.
You can enable the immutability feature for any tier of scale-out backup repository.
To learn how immutability works with performance tier of the scale-out backup repository, see Immutability for Performance Tier.
To learn how immutability works with capacity tier of the scale-out backup repository, see Immutability for Capacity Tier.
To learn how immutability works with archive tier of the scale-out backup repository, see Immutability for Archive Tier.
To use immutability, you must specify the following settings for your object storage:
- Amazon S3 Storage and S3 Compatible
You must enable the Object Lock and Versioning features on your S3 bucket when you create the bucket.
Important |
Note that most vendors allow enabling Object Lock only at the moment of creating the bucket. |
For more information on enabling the Object Lock and Versioning features, see these Amazon articles: Creating a bucket and Enabling versioning on buckets.
- Azure Storage
You must configure immutability policies for blob versions and enable blob versioning for your storage account when you create a storage account.
For more information on enabling immutability for a container, see Microsoft Docs.
For more information on blob versioning for a storage account, see Microsoft Docs.
Important |
When you create the storage account, by default the version-level immutability support option is enabled. You must disable it, otherwise immutability will not be applied for your Azure object storage. For more information, see Microsoft Docs. |
For considerations and limitations on immutability, see Considerations and Limitations.
