You can back up a Vantage VM residing in the Azure public cloud or a Vantage on-premises system to the Azure public cloud using Blob storage as the backup target. The backup may be restored from Blob storage to the same or a different Vantage VM in the Azure public cloud or a Vantage on-premises system.
Before using Blob storage as the backup target for DSU, consider the following limitations:
- DSU supports both hot and cold Blob storage, however, only one type may be used for each backup target group.
- Only one DSC repository may be used. Backup jobs may not be exported from one DSC and imported into another DSC.
- The target group for back up and restore of the DSC repository cannot be Blob storage, but must be a local disk file system.
Initial configuration of Blob storage target groups must be completed using the Teradata BAR portlets. See the Teradata® DSA User Guide.
Storage allocation expands automatically up to the maximum Azure storage account capacity. See Azure Documentation Center for more information on Azure storage account limits and performance targets.
