There are two ways QoreStor lets you use cloud storage containers: as secondary, policy-based storage or as primary storage with optimized deduplication.
Policy-based cloud storage
Policy-based cloud storage is available to any compatible backup software. It requires that you configure a schedule for when QoreStor automatically transfers backups to cloud storage.
There are three purposes for using policy-based cloud storage:
- Replication
- Tiering
- Archiving
For replication and tiering, the cloud storage group remains online, keeping the data accessible. For archiving, QoreStor uses offline Glacier storage, which is designed to store data for longer terms.
For more information about creating a cloud or archive tier, see Cloud tiering.
Direct-to-cloud storage
Direct-to-cloud storage is the feature that QoreStor offers which lets you store backed up data directly to a cloud container. The container can be in either the cloud storage group or the archive storage group. This feature is available only for NetVault backups. After you create the RDS container, you can enter the name of this container in the NetVault GUI as your primary storage location. QoreStor then automatically saves the backups to the cloud, performing optimized deduplication them during the process. Because the backups go directly to the container, QoreStor does not use the policy manager.
When you back up data from NetVault to a direct cloud container, the container behaves the same as any other QoreStor RDS container. The data is easily accessible, which lets you perform the following operations:
- Listing
- Editing
- Backup
- Restore
For more information about creating a direct-to-cloud container, see Configuring an RDS direct-to-cloud container.
Limitations of direct-to-cloud containers
Direct cloud containers include the following limitations:
- Only NetVault is compatible with the direct-to-cloud containers. You can use the cloud container as primary storage only when storing NetVault backups.
- You can access and control the direct cloud container only through QoreStor. Although only NetVaultis compatible with the direct cloud container feature, the container does not appear as a repository in the NetVault UI and NetVault is not aware of its existence. The backups still pass through QoreStor to reach their destination.
- Archive tiers do not function as direct cloud containers. Verification is required for direct cloud containers, but data in Glacier containers is offline and inaccessible.
- Quest discourages using direct cloud containers as sources. When replicating, QoreStor recommends that you always use the RDS direct container as a target rather than a source repository.
