Backing up the existing Horizon configuration

By default, each Horizon Connection Server backs up the AD LDS database nightly to a local folder; this backup is key to restoring the configuration of the Pod-wide Horizon AD LDS instance were there problems with the upgrade. Chapter 3, Implementing Horizon Composer, talks about backing up the Composer database, which should also be performed prior to an upgrade. The following list summarizes the backups we should make or verify prior to performing an upgrade:

• Horizon AD LDS database: Performed by default, but can be done on demand as described later on in this chapter. Each Horizon Connection Server hosts a copy of this backup.
• Horizon event database: Backed up using native backup procedures for the hosting database platform.
• Horizon vCenter databases: These databases would typically not be impacted by a Horizon upgrade, but as mentioned later in this chapter they are critical to any larger Horizon disaster recovery operations.
