What are
configuration object snapshots?
On the BIG-IQ, a
configuration object
snapshot
is a backup copy of the module-specific object configuration settings
that the BIG-IQ uses. You can create a snapshot of the current object configurations
defined on the BIG-IQ to provide yourself a restore point. With this restore point, you can
freely experiment with configuration settings, knowing that you can easily restore the
BIG-IQ back to a known good collection of configuration settings. Before you proceed, keep in mind that there are several different
ways to make backups of your data. Each of these methods backs up different things and is
documented separately.
For type of Backup | Look here for the documentation |
|---|---|
Configuration object snapshots back up the settings for configuration
objects that reside on your managed BIG-IP devices. | This task is detailed in this guide. |
DCD snapshots back up the alert, event, and
analytics data collected by your DCDs. | Refer to Managing
Data Collection Device Snapshots in the Setting up and Configuring a BIG-IQ Centralized Management Solution
article on support.f5.com for details. |
To back up the entire configuration of a managed
BIG-IP device, you create a compressed user configuration set (UCS). | Refer to Managing
BIG-IP UCS Backup and Restore in the Managing BIG-IP Devices from BIG-IQ article on support.f5.com for
details. |
To back up the entire configuration of a BIG-IQ
system, you create a compressed user configuration set (UCS). | Refer to Managing
BIG-IQ UCS Backup and Restore in the Setting up and Configuring a BIG-IQ Centralized Management Solution
article on support.f5.com for details. |
As with most other object configuration settings,
creating a snapshot or restoring from a snapshot does nothing to the object settings on the
managed device until and unless you deploy those settings to the managed device.
This table shows common configuration object snapshot work flow tasks
and descriptions.
Task | Description | For details on this task |
|---|---|---|
Create Snapshot | Creating a snapshot makes a copy of the
configuration settings that the BIG-IQ currently has stored for the objects on
a managed device. | Refer to Create a
snapshot on support.f5.com . |
Compare Snapshot | You can either compare a snapshot to the present
BIG-IQ object configuration settings, or you can compare two snapshots. | Refer to Compare
snapshots on support.f5.com . |
Restore | When you want to revert configuration settings,
choose a snapshot that contains the settings you want, and restore
them. | Refer to Restore some
objects from a snapshot or Restore all
objects from a snapshot on support.f5.com . |
Deploy | If the configuration changes you are reverting were
deployed to a managed device or if you are reverting after importing objects
from a managed device, you need to deploy the settings to the managed device to
get back to the known good state that you used to create the snapshot. | Refer to Create a
snapshot on support.f5.com . |
Configuration snapshots are created manually. This
type of snapshot does not include events or alerts.
If an Access group version changes to a later BIG-IQ version and
you attempt to restore a snapshot created during the previous version, then restoring that
snapshot can cause working configuration changes that can cause a deployment failure.
