As MySQL gains widespread adoption and moves more broadly into the enterprise, ZRM for MySQL addresses the growing need among database administrators to protect their digital assets with a comprehensive backup and recovery solution. The Zmanda Disaster Recovery Solution for MySQL provides robust and cost-effective disaster recovery capabilities for your critical MySQL databases. By deploying the Disaster Recovery (DR) Option for MySQL you can avoid the cost and complexity of replicating each individual MySQL database.
The solution provides full failover and restoration capability for your ZRM implementation. Leverage our Expertise: Zmanda Professional Services engineers have extensive experience creating backup strategies across all MySQL storage engines and configurations. This excerpt from "System Center Operations Manager 2007 Unleashed" helps prepare you for the possibility of a catastrophic failure, and guides you through the process of recovering from a total loss or a downed RMS. This chapter excerpt from System Center Operations Manager 2007 Unleashed, by Kerrie Meyler, Cameron Fuller, John Joyner and Andy Dominey, is printed with permission from Sams Publishing, Copyright 2008. Although we hope you never need to restore Operations Manager from a catastrophic failure, you must be prepared for the possibility that this could happen. Your plan should assume the worst but be able to concisely and efficiently restore Operations Manager at a minimum to the last backup of your databases. Install Operations Manager 2007 from the installation media—selecting the option for a typical installation and using the same management group name as the original install.
You should have a well-documented recovery plan that would work for every conceivable type of disaster that could occur, from hardware failures to a total datacenter loss. This concept would take backups of the physical drives you used when installing and configuring Operations Manager, and convert them to virtual drives.
If you reside outside of the United States, you consent to having your personal data transferred to and processed in the United States. Specify the same accounts (SDK and Config service, Management Server Action account) as used by your original installation.
However, for small businesses, disaster recovery may be deemed costly or an unnecessary expense.Disaster recovery is an important aspect of business continuity.
Figure 12.23 illustrates a sample disaster recovery solution that includes log shipping for the Operational and Data Warehouse databases. If your RMS is down and you will not be available to meet your SLAs, you will want to promote an existing management server to become the RMS, as depicted in Figure 12.24. If you need to recover your systems, you would restore database backups, promote the management server to become the RMS, and connect the systems.


These allow the network to smoothly transition to the redundant server in the event of a main server outage due to traffic spikes, failure, or other issue. Cancer cells until it triggers with you trigger of all the perservatives in them and just even equally.
Amanda Enterprise should be on the short list of any IT manager looking for a backup solution. The Zmanda Disaster Recovery Solution provides robust and cost-effective disaster recovery capabilities for your critical data assets. The DR Option for Amanda Enterprise supports all platforms and applications backed up by Amanda Enterprise: filesystem data on systems running Linux, Solaris, Windows, and Mac OS X as well as application and database data residing in MS Exchange, MS SharePoint, MS SQL, Oracle and Postgres. Leverage our Expertise: Zmanda Professional Services engineers have extensive experience creating backup strategies across all supported system types, storage devices, and operating systems. Affordable: The Zmanda Disaster Recovery Solution is available as an annual subscription that includes implementation, through secured remote shell, by Zmanda Professional Services. You backup all your critical databases to the ZRM server already; the DR Option replicates all your backup archives, backup catalog and configuration to the remote server.
There are at two potential scenarios for disaster recovery, discussed in the next sections. Import any additional management packs that were loaded to your old management server or changed and backed up after your last Operational database backup. You need to not only develop a detailed plan for the various contingencies, but should also practice the various scenarios in a development environment until you (and others on your staff for when you are not available) are comfortable with the process. Those with on-premises infrastructure will often invest in additional disaster-recovery tools, such as remote backups, archives, etc. This tool, Operations Manager Inventory, collects information about your installation and saves it to a XML-formatted .cab file.
Another approach to use virtualization to provide an off-site disaster recovery solution would be through sending regularly scheduled backups of the virtual hard drives to the disaster recovery location. It will outline several disaster scenarios, define the detailed responses to each while aiming to keep impact to a minimum. Although this is a very simple implementation of Operations Manager, it is intended to show you the steps necessary to recover OpsMgr from a complete hardware failure of the management server. In addition to deploying log shipping, you will need the RMS and SRS encryption keys for a successful recovery. We will assume that our server team has already built a new server using the same NetBIOS name in the same domain, installed SQL Server 2005, and enabled IIS because we will use the OpsMgr 2007 Web console.


The appropriate level of service packs and security patches are applied—be sure to be at the same level of software maintenance that you had with your original system. In the event of a disaster, the backup copies of the virtual hard drives are activated and IP address changes made to reflect their new physical location. If you’re maintaining a data center, maintain an off-site failover device to monitor your system health and reroute traffic in real-time, to another data center if your data center experiences failure.ConclusionIn the end, businesses are far safer implementing disaster recovery plans in their operations.
Part of any successful disaster recovery plan includes understanding your current configuration. This prevents OpsMgr from writing data to this database, which you will be overlaying as part of your recovery process. Naturally, from a fiscal standpoint, it makes sense to build disaster recovery into your organization's budget, and with monthly subscriptions that range from less than $100 to a few hundred dollars for a cloud-based DR solution, it’s more affordable than you may realize.Disaster Recovery Concepts to Implement in Your BusinessOne reason why many small businesses skip over disaster recovery is a lack of understanding of its basic concepts. It ensures synchronization of data and backups across distributed infrastructure to keep your business continually running smoothly in the event of hard drive failure, or any other number of IT disasters. In the Save As dialog box, enter a name and location for the .cab file the tool will create.
Your actual plan should contain greater detail, including specific hard drive configurations, the exact installation options, the SQL steps necessary to delete and restore the databases, and so forth. The concepts of disaster recovery may have a technical nature, but aren’t as complex as one may believe.The recovery time objective, or RTO, is the maximum desired length of time between an unexpected failure or disaster and the resumption of normal operations and service levels.
The benefit of a investing either in infrastructure or a monthly subscription – in the case of SME-oriented cloud services – to protect yourself from disaster is definitely worth the investment compared to the potential loss of revenue and the damage to your reputation as a result of downtime or online security issues. The moderated business community for business intelligence, predictive analytics, and data professionals. As we discuss in Chapter 10, log shipping automates the process of backing up database transaction logs and storing them on a standby server. The RTO defines the length of time that is allowed to pass between system failure and repair before the consequences of the service interruption become unacceptable.The recovery point objective, or RPO, is the maximum amount of data allowed to be lost, measured in time. This serves to reduce or eliminate the impact on users when a system fails.Redundancies are duplicate servers, attached to the network but ran offline.
