Copying Backups to Object Storage

Veeam Backup & Replication allows you to copy backups from the extents of your scale-out backup repository to object storage as soon as these backups are created.

To copy data to object storage, Veeam Backup & Replication uses a copy session that is executed automatically upon completion of a backup (or backup copy) job that is targeted to a scale-out backup repository that was extended with object storage.

A complete name of each copy session is built up of the backup (or backup copy) job name + the Offload postfix. That is, if your backup (or backup copy) job name is Amazon, the copy session name will be Amazon Offload.

Once the backup (or backup copy) job is complete, Veeam Backup & Replication initiates a new copy session which simply extracts data blocks and metadata from each new backup file (.vbk, .vib, .vrb) created on any of the extents of your scale-out backup repository and copies these blocks to object storage, thereby making an identical replica of your backup data.

Having such a replica gives you the ability to quickly restore data as of the latest state in case of any unexpected failure of any of your extents, or even of the entire scale-out backup repository, as described in Restore Scenarios.

To enable data copy, make sure to select the Copy backups to object storage as soon as they are created option, as described in Add Capacity Tier.

Combining Copy and Move Operations

You can combine both the Copy backups to object storage as soon as they are created option and the Move backups to object storage as they age out of the operational restores window option. In such a scenario, a copy session will be copying newly created backups right upon creation.

Once the backup chain becomes inactive (or sealed) and exceeds the operational restore window, data blocks will be removed from each associated backup file in such an inactive on-premises backup chain and only metadata will be preserved. Such a behavior mimics data movement, but instead of moving data that was already copied, Veeam Backup & Replication simply purges associated data blocks from the extents, thereby saving traffic and reducing costs that might be incurred by your storage provider for performing read/write operations.

The following figure shows an example in which both options are enabled, suggesting that each backup file has been copied to object storage upon its creation.

The backup chain on the left becomes inactive after a new full backup file is created and consists of one .vbk file and five .vib files. Since only the first four backup files (represented as grey blocks) in this inactive backup chain exceed the operational restore window, Veeam Backup & Replication removes blocks of data from these four files only and leaves the other two .vib files (created on Thursday and Friday) as they are until the operational restore window moves forward, and so on.

Copying New Backups to Object Storage

After copy is complete, the new Object Storage node appears in the Home view, under the Backups node and shows backups that have been copied to object storage.

Copying Backups to Object Storage Note:

The copy is not performed in any of the following cases:

  • During prohibited hours specified in the backup window configuration.
