Create and restore a snapshot of an SBC SWe instance (standalone or HA pair) on Amazon Web Services (AWS).
Topic | Limitations/Guidelines |
---|---|
Stopping an instance | To preserve data integrity, an instance must be stopped before a snapshot is taken. |
Stopping an instance for HA pairs | For HA pairs, stop the standby instance first, and then stop the active instance before taking the snapshot. Stop the instance where the sbxstatus shows standby, or where it does not show active. |
Restoring an instance | The snapshot of an instance is used to restore that instance alone; the snapshot cannot be used to restore another instance. This guideline also applies to HA pairs; the snapshot of an active instance cannot be used to perform a restoration on the standby instance. |
Creating a new Instance from a snapshot | If you create a brand new instance from a snapshot of an SBC, the new instance is created, but one of the instances needs to be deleted for the others to work. For example,
|
Creating multiple snapshots | When creating multiple snapshots of an instance at the same time, the following restrictions apply:
|
A Root Device Volume ID (EBS ID) is associated with each SBC instance, and is used to create a SBC SWe snapshot. Identify the applicable Root Device Volume ID (EBS ID) as follows:
Before beginning this process, perform a backup of the SBC SWe system.
In the Create Snapshot window:
a. Enter the root volume ID of the instance (active instance if HA pair).
b. Enter the desired name for the snapshot.
c. Enter a description for the snapshot.
d. Click Create.
The steps below detail how to restore an SBC SWe instance from a snapshot.
Detach the root volume from the instance (active if HA pair). Repeat for standby instance.
a. Identify the root device volume ID of instance (see Identify the Root Device Volume ID).
b. From the left pane, select ELASTIC BLOCK STORE > Volumes.
c. Select Volume ID as the search filter and type in the volume ID.
d. Click on the volume to select it.
e. From the Action drop down list, select Force Detach Volumes.
f. Click Yes, Detach. The volume is detached from the instance.
g. From the Action drop down list, select Delete. The volume is deleted.
There are two methods for creating a new volume from a snapshot: Method 1 or Method 2.
Create a new volume from the snapshot for the active instance, and then repeat for the standby instance.
Click Create Volume.
