Backup Policies for the HubStor Backup Service

Backup policies allow you to define a backup schedule, control backup destinations, and retention, as well as other options. You can assign backup policies to VMs or folders to control the backup of those entities.

You can assign backup policies anywhere in the hierarchy. The policies will be inherited by descendants unless you specify a different policy, or no policy, for specific VMs.

You can create as many backup policies as you want to cover VMs with differing backup requirements.

Note: Currently, the HubStor Backup Service does not support backing up VMWare templates. If you attempt to back up a template, it will generate an error.

Add Backup Policy Wizard

Launch the backup policy wizard by right clicking the Backup Policies node and selecting "Add backup policy…".



Alternatively, select the Backup Policies node, then click the "Create a new backup policy…" link in the Getting Started pane.




You can find more information about the steps in the wizard in the sections below.

When the wizard completes, you can select an existing backup policy to modify its settings.

Summary



The Summary pane provides information about the VMs protected by the selected backup policy.

# VMs Protected: The number of VMs assigned this backup policy. Stale VMs, show in yellow, are VMs that are not current. VMs with errors are shown in red.

Local Cache Space Used: The amount of space that backup sets are using in the local cache used by this backup set.

HubStor Space Used: The amount of space the backups are using in HubStor

Protected VMs: A list of VMs that are currently assigned this backup policy.

Right click a VM in the list for additional options.


Select "Properties..." to jump to that VM in the "All Content" tree.

Select "Backup now…" to initiate a full or incremental backup .



Stop protecting a VM by clicking "Stop protecting VM…". The backup policy for the VM will be set to No Backup. (refresh may be required)




General Settings



Display Name
: The name of the backup policy

Description: An optional description

Pre-ingest Encryption Key: To encrypt your data prior to sending it to HubStor, you can specify an encryption key. Please contact HubStor Support prior to enabling this option.

Backup Schedule



A backup set consists of a full backup, plus optional incremental backups. You can schedule the frequency of each type of backup. (Daily, Weekly, Monthly, Every N Days, etc.) You can set the backup window to "Anytime" or "Non-business Hours". You can configure non-business hours. For more information about "Backup Settings" see SETTINGS FOR THE HUBSTOR BACKUP SERVICE.

Backup Destination



Local Copy: If you are using a local cache, select the cache from the list. Otherwise, select "None". For more information about creating a local cache, see LOCAL CACHES FOR THE HUBSTOR BACKUP SERVICE.

Cloud Copy: Select a HubStor location to store your VMs.

Note: If you have a dedicated HubStor tenant, please contact HubStor Support to create a Stor specifically for the HubStor Backup Service.

Backup Retention


Local Copy Retention



Specify the number of backup you wish to keep in the local cache. A backup set consists of a full backup, plus optional incremental backups.


Cloud Copy Retention


You can reduce the number of backups stored in HubStor by specifying the number of latest, weekly, monthly, and yearly backups to retain. The HubStor Backup Service will prune backups when the service starts and every 24 hours thereafter.

Keep N Latest Backup Sets - Specify the number of backup sets that the HubStor Backup Service must retain. This setting overrides any of the below settings for pruning and deletion.
Then Keep Weekly Backups for N Weeks - Once the above number of backup sets is reached, the HubStor Backup Service will remove all incremental backups and only retain this number of full weekly backups. (This setting only applies when the full backup schedule is daily or weekly.)
Then Keep Monthly Backups for N Months - Once the above number of weekly backups is reached, the HubStor Backup Service will delete backups and only retain one full backup per month. Note: The specific day of the monthly backups may differ by a day or two from one month to the next as the HubStor Backup Service assumes 30 days per month when pruning.
Then Keep Yearly Backups for N Years - Once the above number of monthly backups is reached, the HubStor Backup Service will delete backups and only retain one full backup per year. Any older backups are deleted.
Note: The HubStor Backup Service will not consider backups with errors when pruning backups. You can delete backups with errors from the "Backup Sets" tab of a virtual machine node.
Note: Local copies must also have a corresponding cloud copy. For example, you cannot retain 3 backup sets locally and only 1 in the cloud. Similarly, if you set "Keep N Latest Backup Sets" to 0 (retain all) in "Local Copy Retention", you must also set "Keep N Latest Backup Sets" to 0 (retain all) in "Cloud Copy Retention".

Assigning a Backup Policy

Select any node in the hierarchy and select the Backup Policy tab. Policies will be inherited by descendants unless you specify a different policy, or no policy, for specific nodes or VMs.


No Backup: Select this option if you do not want to back up the specific VM or node (and its descendants).
Inherit Backup: Select this option if this node or VM should inheriting a backup policy. The backup policy will be shown in parenthesis if one is being inherited.
Explicit Backup Policy: Select this option if you want to use a specific backup policy when backing up the specific VM or node (and its descendants).
