Veeam Customer Support will not support environments where some or all of backup files' data is being offloaded to another storage with 3rd party solutions. For additional information, please refer to the
User Guide.
Veeam Customer Support is unable to assist with failed restores from copies of backups made by 3rd party solutions, because Veeam cannot guarantee that the backup files' data was correctly managed by the 3rd party application, and is consistent. This is especially true with object storage, which often provides "eventual consistency" only.
