In our effort to reduce tape media for backup, we have relied on disks for our backup and disaster recovery solution. Disks are getting cheaper and de-duplication technology keeps on improving. We still use tapes for archiving purposes.

One very useful tool for managing our backup and disaster recovery infrastructure is NetApp Protection Manager. It has replaced the management of local snapshots, snapmirror to Disaster Recovery (DR) site, and snapvault. In fact, it doesn’t use these terms anymore. Instead of “snapshot,” it uses “backup.” Instead of “snapmirror,” it uses the phrase “backup to disaster recovery secondary.” Instead of “snapvault,” it uses “DR backup or secondary backup.”

NetApp Protection Manager is policy-based (e.g. backup primary data every day @ 6pm, and retain backups for 12 weeks; backup primary data to DR site every day @ 12am; backup the secondary data every day @ 8am and retain for 1 year). As an administrator, one does not have to deal with the nitty-gritty technical details of snapshots, snapmirror, and snapvault.

There is a learning curve in understanding and using Protection Manager. I have been managing NetApp storage for several years and I am more familiar with snapshots, snapmirror, and snapvault. But as soon as I understood the philosophy behind the tool, it gets easier to use it. NetApp is positioning it for the cloud. The tool also has dashboards intended for managers and executives.
