Backup and disaster recovery solutions are now easy to manage for different situations. The first crucial step is deciding how to handle a permanent archive and how often data is taken offsite and to what frequency. Upon defining Recovery Time Objective (RTO) and Recovery Point Objective (RPO) for different types of scenarios, a comprehensive backup and recovery plan can be designed.
A recovery solution may be as simple as restoring a deleted file or a complete server, the recovery point is as far as the previous nights’ backup. A file restore still has a simple and very fast restoration time within minutes. While a server recovery upon a hardware failure can take several days to get back into production with the current environment.
Now that server virtualization is more affordable and being used in production, the backup and recovery strategies can change the RPO and RTO dramatically. The traditional disk to tape is no longer a constraint for dictating all of the recovery scenarios that may arise.
VMware provides virtual snap shots to apply patches and applications to a server in a test environment without impacting production and going through a lengthy process to create the test server or servers. VMware also leverages the Equal Logic SAN to provide an easy and fast recovery from a physical server hardware failure within minutes.
The Equal Logic SAN can be leveraged for multiple snap shots per day that can be kept and used for entire virtual server recoveries within minutes.
The granular capability of backup to disk software also allows files and databases to be saved multiple times per day. Files can now be restored to multiple points in time by the end user out of Windows Explorer by leveraging Microsoft’s Data Protection Manager.
Another component can be introduced for getting data offsite to another remote server on a nightly basis eliminating nightly tape backups and weekly off site tape rotations. Then it is just a matter of how to handle any permanent archive, which is accomplished by tape or hard drive. The hard drive can be space at a secure facility such as a hosted data center. Most services allow up to 7 years for such long term storage of data. This is more often an expensive method as simply buying hard drives every month is far more affordable since the price for hard drives are now a couple hundred dollars and hold up to 2 TB.
