Enabling External Blobstore Backups
Page last updated:
This topic provides instructions for enabling external blobstore backups in your Pivotal Application Service (PAS) tile.
BOSH Backup and Restore (BBR) supports the following:
- 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. See Enable Backup Restore Node in Backing Up Pivotal Cloud Foundry with BBR.
External blobstore backup support varies based on which version of 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.
Refer to the table below to determine if external blobstore support is included in the version of Ops Manager you are using.
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 Configuring Load Balancing for PAS.
- 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 Enable Replication on Your External Blobstore in Backup and Restore with External Blobstores in the Cloud Foundry documentation.
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, Configuring Load Balancing for PAS.
To save storage space and cost, Pivotal recommends that you configure a retention policy to permanently delete objects after a period of time.
