About immutable storage support for Google Cloud Storage

NetBackup 10.2 and later versions support the Google immutable cloud storage to store the backup data. For more information about Google bucket level retention policy, see Retention policies and retention policy locks.

Enable the retention policy on a bucket. It ensures that all the objects in the bucket cannot be deleted or replaced until they reach the age you define in the retention policy.

  • Locked retention policy

    You cannot overwrite or delete the data that is protected using the locked policy for the defined retention period. Once you set a retention period for the bucket, you can extend it but cannot shorten or remove it.

  • Unlocked retention policy

    You cannot overwrite or delete the data that is protected using the unlocked policy for the defined retention period. Once you set a retention period for the bucket, you can extend, shorten, or delete it.

The bucket level retention period must be twice of the retention period of the backup images that are stored in this bucket. For example, if the backup image retention period is one year, the bucket level retention period must be 2 years.

The bucket may have multiple cloud volumes. Retention policy for the bucket protects backup images of all the volumes.

Limitations:

  • You cannot shorten the bucket level retention period. Some existing image data may lose the retention protection if the retention period is shortened.

  • You cannot remove the bucket level retention policy when it is unlocked. All existing image data loses the retention protection if the retention period is removed.

  • Does not support accelerator backup.

  • Does not support image sharing. Image sharing import lists the failed backup image.

  • Does not support NetBackup for AKS/EKS and NetBackup Flex Scale.
