There are MS Exchange admins out there that if you ask them how long does it take to recovery an Exchange server, you will see them shudder over the thought. And those who are recovering from tape? It gets even worse. I know there are requirements for tape and there are some that still like putting a tape in a fire proof safe just in case but lets talk about recovery.
Messaging is increasing becoming a top priority in companies around the world. We use it to communicate latest releases, respond to clients requests, get the scores from last night. It may not be as important as keeping the SAP database online, but its provides value that is noticed when down.
Not all recoveries are done through swinging the entire data center through the DR strategy. There are times when we need to restore a mailbox for legal reasons or people asking for certain emails to be brought back from an errand delete. How quick is your restore at that point? Can you pull the data off tape quicker than someone can recreate the excel spreadsheet?
With SnapManager for Exchange, we can quickly backup and restore exchange mailboxes. The same technology that we use for file level snapshots apply to here to a database. We put the database into a backup mode and take a consistent snapshot of the data with out the end user noticing. Backups can then be mirrored to another system either at a DR site or just another exchange cluster. This allows you to have a point in time capture of the data in case you need to restore.
Restores seem to be the more of the headache for most admins. With the snapshot restore via SnapManger for Exchange, an admin can simple choose which recovery point they want to restore from and they can have the data restore over the production or they can restore to a recovery storage post. The restore is quick and is intuitive which also cuts down on the overall recovery time.
Here is a quick video of the backup and restore function of SnapManager for Exchange.

I have been asked about the VMware SRM tool a few times this week and its already Tuesday. Netapp has published a great demo on you tube that goes through the process of protecting the VMware environment. SRM allows VMware administrators to automate and test the disaster recovery strategy.
The main question people are asking is how do we know the DR site data is going to work when we really need it. For most customers I have suggested using the flex clone technology that allows you to clone a volume from a snapshot. This cloned volume does not take any more space from the N series system which allows you to create multiple copies of the volume if needed.
SRM automates this process of snapmirroring the virtual machines and the creation of the cloned VMs. Here is a great video of the tool and how it works.

Pretty cool demo of doing a file level restore from a clone using a mounted snapshot. I could see this being useful for storage admins that want to get out of doing restores for those other admins. Simply send them an email with the link and let them do their own restore.
