Peer Backup Assistant: High Availability (deprecated)

Note

This step is deprecated, and you should use the Peer Backup Assistant: Finalize Nomad PBA Data Store instead. Existing deployments will still work, but you cannot modify them. Going forward, we recommend using its replacement.

This step stores additional backup copies of the PBA data store, after the primary data store has been created with Peer Backup Assistant: Provision Nomad PBA Data Store and after the USMT data has been saved andc losed with Peer Backup Assistant: Close Nomad PBA Data Store (deprecated).

The following actions must have been run successfully:

  • Peer Backup Assistant: Provision Nomad PBA Data Store

  • USMT Save User State

  • Peer Backup Assistant: Close Nomad PBA Data Store (deprecated).

This custom action is available in the 1E Nomad PBA task sequence actions .

Actions

Notes

When run, this task:

  1. Polls Nomad peers enabled for PBA to find the required number of data stores where the user state may be saved.

  2. Backs up the primary data store on each Nomad peer after locating the PBA data stores.

This task sequence:

  • Must have the minimum and maximum number of PBA data stored to create defined

  • Must have the number of synchronous backups that must be completed successfully defined before continuing with the next action in the task sequence. The remainder of the additional backups are performed asynchronously while the other task sequence actions are running.

Configurable parameters

Parameter

Default value

Description

Name

Peer Backup Assistant: High Availability.

Name for the custom task sequence step.

Description

Action to find additional PBA data stores for saving user state.

Description for the custom task sequence action.

Minimum

1

The minimum number of PBA data store backups. Must be at least 1 and not greater than 6. The specified number (minimum) of data stores must be available when PBA-HA starts backing up the data. If the minimum number of data stores will not respond, then the PBA-HA task sequence step will fail.

Note

The minimum should be greater than or equal to the Synchronous value. If the minimum number is less than the Synchronous value, the task sequence may fail even though the minimum number of backups have been done.

Maximum

1

The maximum number of PBA data store backups. Must be at least equal to the minimum and not greater than 6.

Synchronous

1

The number of backups that must be performed successfully before moving onto the next action in the task sequence. Must be 0 or more and not greater than the value set for the maximum.

Note

It is possible, but not recommended, to set this value to 0. If this is done, the next action in the task sequence will start immediately, but there will be no guarantee that any backups have been successful.
