Dataprotector

The recovery of an Exchange mailbox using a recovery database is usually no big deal. Simply restore the database, create a recovery database and recover the mailbox or items from the mailbox. Sometimes you have the luck that the customer has licensed the Data Protector Exchange 2010 Granular Recovery for Exchange (GRE). This was unfortunately not true in my case. Okay, so let’s do it the old way. The needed tape was available in the library and luckily it was a full backup. So I quickly added a disk to the VM and started the recovery of the database to a temporary location. At this point, the disaster took its course…

HP StoreOnce Catalyst is an enterprise-wide deduplication algorithm which is used in HP StoreOnce appliances, HP StoreOnce VSA and HP Data Protector. With StoreOnce Catalyst, deduplicated data can be moved between Catalyst capable devices without the need to rehydrate the data. Think about the backup in your remote location. You can move the deduplicated data to your central StoreOnce appliance in your HQ without rehydrating the data. This saves bandwidth and time. Or think about source-side deduplication, which means that a server deduplicates the data during the backup and sends the deduplicated data to the backup device. This saves bandwidth and increases the performance (with the downside of more cpu load on the server…).

Sometimes it’s necessary to backup system, that are behind a firewall. A good example for this are servers in a DMZ. When using HP Data Protector there are some things to know and consider, before you can backup systems behind a firewall. Lets start with some basics.
