Configuring the Cloud objects tab

The Cloud objects tab lets you select the Cloud object store account that you want to use to connect to cloud resources to protect objects in the desired buckets. NetBackup lets you make a discrete selection of the buckets/containers and objects that you want to protect using the policy. You can use queries to intelligently filter and select the items that you want to protect.

NetBackup supports a single backup host or scale-out server per policy. Hence, to distribute the load, you have to create multiple policies, and using queries, you can bifurcate the load of buckets/objects being backed up across multiple backup hosts or scale-out servers.

To configure cloud objects:

  1. Select a Cloud object store account and Host. You can see a list of accounts and backup hosts that you are privileged to access. If you use a scale-out server for the account, the Host field is disabled. You cannot change a scale-out server while creating a policy.
  2. (Optional) Select the Allow dynamic multi-streaming option to allow NetBackup to divide automatic backups for each bucket/container into concurrent multiple streams. This option can dramatically improve the backup time of the protected buckets/containers.

    In the field, Maximum number of streams per bucket/container specify a number between 1 to 64. The default value is 8.

    Some streams may go to a queue, if the maximum number of concurrent jobs allowed in the storage unit selected for the policy, is less than the total number of streams that are running for the policy. For optimal performance, keep the Maximum concurrent jobs allowed property of selected storage greater than the total number of streams that you expect the policy to handle. The minimum value for the Maximum concurrent jobs for the storage must be 64.

    Optionally, specify a Temporary staging location path, or use the default path. You can leave this field blank to use the default path. See Configure a temporary staging location.

    Note:

    If you enable dynamic multi-streaming, all selected buckets and containers are completely backed up. You cannot define any queries for the buckets or containers that you have selected.

  3. To add buckets/containers, click Add near the Buckets/Containers table. In the Add bucket/containers dialog, do any of the following to add buckets/containers.
    • To add a particular container, enter the name in the Bucket/Container name field, and click Add.

    • Select one or more bucket/container from the Bucket/Containers table, and click Add. You can use the search box above the table to filter the list.

    If the Cloud object store account credentials do not have permission to list buckets, the bucket list remains empty. But you can manually add buckets.

    In the Cloud objects tab, click Remove in the row of any bucket/container name in the Buckets/Containers table to remove it from the policy. Enter a keyword in the search box to filter the table.

  4. To add a query to the selected buckets/containers, click Add query under Queries.
  5. Enter a name for the query, and select the buckets that you want to filter using the query.
  6. In the Select objects/blobs table, select the option Include all objects/blobs in the selected buckets/containers to backup one or more entire buckets.
  7. Under Buckets with no queries, select the buckets/containers to which you want to add queries. If a bucket is previously selected to include all queries, that bucket does not appear in this list. Click Add condition or Add Tag condition to add a condition or a tag condition. See Adding conditions . and See Adding tag conditions . respectively, for more details.
