Considerations and Limitations

This section lists considerations and known limitations for object storage repositories.

General

  • Make sure to open required ports to communicate with object storage repositories in advance, as described in Used Ports.
  • Make sure the S3 Compatible device you are adding supports AWS v4 signature. For more information about authentication requests, see this Amazon article.
  • When adding Amazon S3 object storage, only the Standard, Standard-IA and One Zone-IA storage classes are supported. For more information about Amazon S3 storage classes, see this Amazon article.
  • For Microsoft Azure Blob Storage, Veeam Backup & Replication supports specific types of storage accounts and tiers. For more information, see Microsoft Azure Storage Accounts.
  • Object storage gateway appliances that are used to store backup data in filer (CIFS/NFS) or block device mode (iSCSI/FC/SAS) are not supported if the backup data is offloaded to object storage and is no longer stored directly on the appliance.

Such gateway appliances are only supported in the following cases:

  • All of the backup data is stored on the appliance altogether (that is, all of the backup chains are stored on the appliance as a whole and not scattered across multiple devices) and only additional copies of the backup data are transported to object storage.
  • These appliances emulate a tape system (VTL) as an access protocol for Veeam Backup & Replication.
  • Data in object storage bucket/container must be managed solely by Veeam Backup & Replication, including retention and data management. Enabling lifecycle rules is not supported, and may result in backup and restore failures.
  • If a backup chain contains backup files that are marked as corrupted by Health Check, then such corrupted files, as well as all subsequent files that go after the corrupted one are never offloaded. In such a scenario, offload is only possible starting from the full backup file that succeeds the backup chain with corrupted backups.
  • Different object storage repositories mapped to the same cloud folder can be used for storing both the Capacity Tier backups and the NAS backups.

Considerations and LimitationsImportant!

The same object storage repository (mapped to the same cloud folder) must not be used across multiple Veeam Backup & Replication servers for the same purposes as it leads to unpredictable system behavior and inevitable data loss.

For the same reason, two object storage repositories mapped to the same cloud folder must not be added to different scale-out backup repositories within one Veeam Backup & Replication server.

There is a misspelling right here:

 

I want to let the Veeam Documentation Team know about that.
