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.

IBM N series Release News 3 of 4
The past two days I have been writing about new technologies IBM released on October 20th. There was plenty of hardware to help IBM customers to get more bang for the buck but there was also an addition the SnapManager suite; SnapManager for Hyper-V.
One of the biggest chances in the data center has been the server virtualization of the data center. This new idea of consolidating the server farm from multiple 1 U servers to a larger server hosting multiple virtual machines posed new challenges. Backup, restores, IO bottle necks; all new things we had to work through.
For many years VMWare was the main player in the virtual server game. As the virtual movement caught more traction with customers, other vendors started coming out with their own virtual products. Microsoft released their virtual product codename Viridian, with their Windows 2008 OS and named it Hyper-V.
IBM SnapManager suite allows customers to take a consistent backups of databases and Hyper-V is no different. Built on snapshot technology, SMHV takes snapshots of the VM. Some of the terms used with Hyper –V is different than VMWare but the idea is pretty much the same.
SMHV uses a group of objects called datasets. These datasets can have certain retention policies set on the dataset. The dataset is backed up collectively but can be restored individually.
There is also Snapmirror integration that helps mirror the datasets to another N series set of disks. Reporting is also a feature that is included.
If you have some time to review the SMHV product, there are a few links you should take a look at:
