Disaster Recovery Disaster Recovery helps you quickly recover and reinstall your McAfee ePO software. To recover your McAfee ePO environment, you must have a backup of the data that is unique to your environment and a mechanism for restoring McAfee ePO using this backup. The data that makes your McAfee ePO environment unique consists of two things: the McAfee ePO database, and sections of the McAfee ePO server file system. For example, the extensions that you checked in and the configuration files that control McAfee ePO. A McAfee ePO database backup containing a valid Disaster Recovery Snapshot allows you to restore: McAfee ePO to your current McAfee ePO server, which allows you to recover from. For example, a failed McAfee ePO software upgrade. McAfee ePO to new server hardware with the original server name and IP address. For example, in the case of catastrophic hardware failure. McAfee ePO server hardware with a new server name, which allows you to move your McAfee ePO server from one domain to another. For security, the files stored in the Snapshot are encrypted using the Keystore Encryption Passphrase. Keep a record of this passphrase; you need it to decrypt the Disaster Recovery Snapshot records and McAfee can't recover it. Important considerations For a successful disaster recovery, the database and the snapshot it contains must be in sync. For example, if you took a Disaster Recovery Snapshot a week ago, two days ago you checked in a new extension, and last night you backed up the McAfee ePO database without taking a new snapshot, the database and snapshot are not in sync and it is unlikely you will be able to successfully restore from that database. The Server Snapshot dashboard monitor can be used to tell you if your snapshot is up to date. To prepare for disaster recovery, save the files to the Snapshot in the database, and then perform a full backup of the McAfee ePO database. Install McAfee ePO software on a restore serverYou can restore the McAfee ePO software as a recovery installation where your Microsoft SQL Server already includes a McAfee ePO configuration from a previous installation. Change the server recovery passphraseYou can change the server recovery passphrase when you install McAfee ePO and link it to a SQL database restored with Disaster Recovery Snapshot records.
