Object Storage as NAS Backup Repository

How File Share Backup to Object Storage Repository Works

You can select an object storage repository added in your backup infrastructure as a backup repository for storing NAS backups.

Types of Connection to Object Storage Repository

Depending on your infrastructure and the activity type, the source general-purpose backup proxy can connect to the object repository through one of the connection types:

  • Direct. In this mode, the general-purpose backup proxy writes directly to the object storage. This connection type is used, for example, for backup and restore sessions when your target object storage repository is located in your local infrastructure.

  • Through gateway servers. In this mode, the backup server automatically selects the most suitable gateway server from the preconfigured list. This connection type is used, for example, for backup copy sessions when the source backup is stored on an SMB or NFS share, or if the target object storage repository is a cloud repository.

The connection type is configured at the Account step of the New Object Storage Repository wizard.

The main peculiarity of storing NAS backups in an object storage repository is keeping a copy of the metadata in the object storage next to the data. The main metadata is stored in the cache repository. This metadata is active: it is actively used during backup, restore, merge, transform, or health check operations. All the changes in the active metadata is then replicated to the metadata copy.

The metadata copy is self-sufficient: if anything happens to the source file share and the cache repository, you still will be able to restore data from the backup stored in the object storage repository.

Helper Appliance in NAS Backup

NAS backup is forever forward incremental and it does not create periodic full backups. To avoid constantly downloading and uploading data for performing transform and health check operations, you can configure a helper appliance. To learn how to configure the helper appliance, see the Mount Server step in Adding S3 Compatible Object Storage, Adding Amazon S3 Storage, Adding Google Cloud Object Storage, Adding IBM Cloud Object Storage, Adding Azure Blob Storage, Adding Wasabi Cloud Object Storage.

Changing Cache Repository

If your file share is protected with a file backup job that backs up data to an object storage and you decide to change the cache repository for this file share, Veeam Backup & Replication will prompt you to:
