Refreshing data in Cloud Reader

When you run the maintenance command with the --quick_ro_recovery, the QoreStor instance only sees what was in cloud bucket at the time the command was done. Later backup data can become expired from the primary QoreStor instance and the Cloud Tier, and new backup data uploads. To see the new file space view, run the same maintenance command. It erases the current view and retrieves the latest view from the cloud.

Configuring RDA immutability

This topic introduces the RDA immutability feature and related concepts and tasks. Refer to the subsequent topics and procedures in this section for more information.

Understanding RDA immutabilty

RDA immutability provides protection from overwrites and deletes on backup files. This technology is present by default for RDS containers, but not all backups are protected by default. Backup applications sending data using the RDA protocol to QoreStor define whether the backup data should be immutable and the time period the data will remain immutable. After you set immutability on the backup data, you cannot modify or delete the backup data from the RDA container until the immutable time period expires. For the current list of supported backup applications that take advantage of this technology, see the Quest QoreStor Interoperability Guide.

Managing containers with RDA immutability

When working with containers that have RDA immutability, take the following conditions into consideration.

Container deletion

Containers with immutability and cloud locked files cannot be deleted until the immutability on all the backup data expires.

Container replication

When container replication is set up between two RDA containers and when replicated backup data includes an immutability time period, the remaining immutability time period is set on the backup data replicated to target containers.

NOTE: It is not possible to add a container with immutable backup data as a replication target.

In case of secondary copy or duplicate operations performed by backup applications over RDA, backup applications set immutability time period on the target backup data.

Cloud Tier and Archive Tier

QoreStor maintains the immutability time period on backup data when it transfers them to a cloud tier or archive tier. During a disaster recovery from a cloud tier or archive tier, the immutable time period is again set on the backup data, making it immutable on new QoreStor instances as well..
