Enabling External Blobstore Backups

Page last updated:

This topic describes enabling external blobstore backups in your Pivotal Application Service (PAS) tile.

BOSH Backup and Restore (BBR) supports:

  • Versioned S3 or S3-compatible blobstores
  • Unversioned S3 or S3-compatible blobstores
  • Azure blobstores

For more information, see Backup and Restore with External Blobstores.

Note: To enable external blobstore backups for PAS, the Backup Restore Node must be enabled. For more information, see Enable Backup Restore Node in the Backing Up Pivotal Cloud Foundry with BBR topic.

External Blobstore Support

External blobstore backup support varies based on which version of Pivotal Ops Manager you are running and what type of blobstore you are backing up.

In some cases, external blobstore support is included in the version of Ops Manager you are using. In other cases, installing Blobstore Add-On is required.

To determine if external blobstore support is included in the version of Ops Manager you are using, see the table below.

Ops Manager Version
Blobstore Type
2.2 2.3 2.4 2.5 2.6
Versioned Included Included Included Included Included
Unversioned Included Included Included Included Included
Azure Add-On Included Included Included Included
GCS Not supported Not supported Not supported Not supported Included

S3 or S3-Compatible Blobstores

In PAS v2.2 and later, BBR supports backing up and restoring versioned and unversioned S3 or S3-compatible blobstores by default. For more information about configuring an S3 or S3-compatible blobstore, see the AWS section of the Configuring File Storage for PAS topic.

Note:
  • Backup artifacts of external, S3-compatible, versioned blobstores do not contain the physical blobs. BBR requires that the original buckets still exist to be restored.
  • To protect yourself from losing a bucket, see the Enable Replication on Your Versioned S3-Compatible Blobstore section of the Backup and Restore for External Blobstores topic.

Azure Blobstores

To configure your Azure blobstore for backups, you must enable soft delete in your Azure Storage account. You can also enable soft delete for existing Azure storage accounts that were not initially created with soft delete enabled. For more information, see Soft delete for Azure Storage blobs in the Microsoft documentation.

After enabling soft delete, you can enable Azure blobstore backups in Ops Manager for new or existing blobstores. For more information, see the Azure section in the Configuring File Storage for PAS topic.

To save storage space and cost, Pivotal recommends that you configure a retention.

GCS Blobstores

For more information about configuring a GCS blobstore, see the GCP section in the Configuring File Storage for PAS topic.
