Before You Begin

This section contains information that you should consider before you create an object storage backup job.

General Considerations

Before you create an object storage backup job, consider the following:

  • The object storage backup feature is available starting from Veeam Backup & Replication 12.1 (build 12.1.0.2131).
  • Consider limitations listed in the Platform Support section.
  • The account that you use to add Amazon S3 and S3 Compatible object storage as unstructured sources and back up data from them must be able to perform the actions listed in the Permissions section.
  • Backup infrastructure components that will take part in the object storage backup process must be added to the backup infrastructure and properly configured. These include objects storage sources to back up, backup proxies, and all repositories, including cache, backup, archive, and secondary repositories. For more information, see the Backup Infrastructure for Unstructured Data Backup section.
  • The target backup repository must have enough free space to store created backup files. If you want to receive notifications on the repository running low on free space, configure global notification settings as described in the Specifying Other Notification Settings section.
  • Make sure that repositories intended to store object storage backups are not configured to store files in the Write Once Read Many (WORM) status. Otherwise, the backup jobs will fail when Veeam Backup & Replication cannot update the backup metadata files.
  • If you plan to map an object storage backup job to a backup that already exists in the backup repository, you must perform the rescan operation for this backup repository. Otherwise, Veeam Backup & Replication will not be able to recognize backup files in the backup repository.

For more information on how to rescan backup repositories, see the Rescanning Backup Repositories section.

  • If you plan to use pre-job and post-job scripts, you must create scripts before you configure the object storage backup job.
  • Antivirus software may significantly slow down object storage backup jobs. To improve performance, we recommend you exclude the c:\Program Files (x86)\Veeam\Backup Transport\x64\VeeamAgent.exe process from the antivirus scan on machines running the object storage backup proxy and backup repository roles. Keep in mind that it can weaken the security of these machines.
  • If the object content and modification time are not changed, Veeam Backup & Replication will back up only attributes of this object.
  • Veeam Backup & Replication does not back up version history of objects.
  • Veeam Backup & Replication does not create the separate node in the inventory pane for the archived backups. If you plan to use archive repositories and want to make sure that backups were moved to it, you can do it using backup properties. For more information, see Viewing Unstructured Data Backup Properties.

Limitations for Microsoft Azure Blob Storage

Before you create an object storage backup job, consider the following limitations for Microsoft Azure Blob storage:

  • Veeam Backup & Replication backs up objects encrypted only with Microsoft-managed and customer-managed keys. If you create a blob using the Put Blob or Put Block List API method and specify a customer-provided key, Veeam Backup & Replication cannot back up such blobs. For more information about customer-provided keys, see this Microsoft article.
  • Backup of ACL for Azure containers.
  • Backup of hierarchical namespace.

Limitations for Amazon S3 Storage

Before you create an object storage backup job, consider the following limitations for Amazon S3 storage:

  • Veeam Backup & Replication backs up objects encrypted only with Amazon S3 managed keys and AWS KMS keys. If you add an object to a bucket using the Put Object API method and specify a customer-provided key, Veeam Backup & Replication cannot back up such objects. For more information about customer-provided keys, see this Amazon article.
  • Veeam Backup & Replication does not support backup of the objects with the Amazon S3 Glacier Flexible Retrieval and Amazon S3 Glacier Deep Archive storage classes.
