State and mode for virtual failover

You can monitor a virtual failover client (VFC) by viewing details about its state and mode in the Windows Instant Recovery Clients screen of the appliance that is managing the VFC. To access this screen, log in to the appliance that is managing the VFC and select Settings > Instant Recovery > Windows. This section explains the different states and modes.

The State column of the Windows Instant Recovery Clients screen indicates the current state of the VFC, for example whether it is a newly created VM, whether a restore is occurring, or whether it is in audit mode (see the table below for descriptions of all the possible states). The state can change depending upon an action requested of the VFC. This action is referred to as a “mode.” The action can be requested by the user or by the appliance managing the VFC.

The table below explains the different modes and states and the relationships between them.

Mode

State

Description

N/A

New

State of a VFC for which no virtual restores have been performed. The VFC remains in this state until a virtual restore has been performed.

Restore

A backup has completed, and the appliance has requested that a restore be performed. The VFC is in the Restore state until the restore completes.

N/A

Idle

At least one backup has been performed to the VFC, but currently no action is occurring.

Restore

Halted

A backup has completed, and the appliance has requested that a restore be performed. The VFC goes into a Halted state if the restore cannot be performed. The following can occur when a VFC is in this state:

•

If the restore could not be performed because the appliance could not reach the VFC, it tries again after several minutes, and the state changes from Halted to Idle. After three failed attempts, the VFC’s status becomes Invalid, and it remains in Halted state until a user deletes it. For more details, see The Unitrends appliance cannot communicate with the virtual failover client.

•

If the restore could not be performed because a configuration change was made to the original client, the VFC’s status becomes Invalid, and it remains in Halted state until a user deletes it. For more details, see Configuration changes have been made to the original client.

For details about Invalid VFCs, see Invalid virtual failover clients. For instructions on deleting a VFC, see Deleting a virtual failover client.

Audit

An audit has been requested by the user, and the VFC has been booted in Audit mode. For details about auditing a VFC, see Auditing a virtual failover client.

N/A

Verify

The user has enabled verification reports. The appliance is taking a screenshot of the VFC’s login screen in Audit mode. This screenshot is sent to the user in an email report to verify the VFC. After the verification completes, the state of the VFC is Idle. For details about verification reports, see Automated audits for a virtual failover client.

Live

The user has requested for the VFC to boot and replace the original client. After the state of the VFC is Live, it is no longer managed by the appliance, and virtual restores are no longer performed. Its status is Invalid. (For details about status, see Viewing virtual failover client details.) Once the state of the VFC is Live, the only other state it can enter is Off.

Live

Off

The user has taken the VFC out of Live mode. A VFC in the Off state can enter Live mode again, but its status is Invalid, and it is no longer eligible for virtual restores.
