I have Veritas 9.1, I'm curious how disaster recovery works.  Anyone use this?  You have to buy the agent to do this as well, correct?

Thanks!

Yes, you do have to buy the Intelligent Disaster Recovery Agent.  You don't need an agent for every server or workstation being backed up, just one for each Backup Exec server running it.

Disaster recovery is designed to decrease the time to recover a server.  If you have to install an OS, configure it a bit, and install the Veritas BE client on the server to be recovered, it could take a little while; and you might have some driver (such as RAID Controller), configuration, or authentication issues.

Disaster recovery is designed to get the server back where it was as quickly as possible.  To do so, basically Veritas uses three pieces of data: 1) a boot medium; 2) a disaster recovery information file; 3) data backup/restore medium.

For the boot medium, I prefer creating bootable CDs.  (Just keep in mind that you might have to adjust the server's BIOS boot order when booting from the CD.  The boot medium will retain the drivers necessary for the hardware in the server.

For the disaster recovery information file, I use a UNC path to a DIFFERENT SERVER THAN THE ONE RUNNING BACKUP EXEC because if the Backup Exec server is the one that needs recovery, it can be recovered without the Veritas databse existing.

For the backup/restore medium, it will be the latest one used for the FULL BACKUP prior to recovery.

The recovery information file will be created when you complete the wizard and perform a full backup.  After that, the file will be added to on a continuous basis after backups so that all data can be restored.

Keep in mind when you design your strategy; the closer to a FULL backup you are, the quicker the recovery, and that's where the overall employee productivity is saved.  If you can fit it into the time window, there is no harm in pereforming complete backups nightly.

Thanks for the quick response gpricee!  I am considering giving this a shot.  At present, we do full backups everynight since it doesn't take to long and we have the time.
