Enabling External Blobstore Backups
Page last updated:
This topic describes enabling external blobstore backups in your VMware Tanzu Application Service for VMs (TAS for VMs) 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 for External Blobstores in the Cloud Foundry documentation.
Note: To enable external blobstore backups for TAS for VMs, you must enable Backup Restore Node. For more information, see Enable Backup Restore Node in Backing Up Deployments 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.
To determine if external blobstore support is included in the version of Ops Manager you are using, see the table below:
|GCS||Not supported||Not supported||Not supported||Not supported||Included|
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 AWS in Configuring File Storage for TAS for VMs.
- 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 Versioned S3-Compatible Blobstore in Backup and Restore for External 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 Azure in Configuring File Storage for TAS for VMs.
To save storage space and cost, VMware recommends that you configure a retention.
For more information about configuring a GCS blobstore, see GCP in Configuring File Storage for TAS for VMs.
