I'm wondering what the purpose of creating an ERD with NTBackup on a Windows 2000 server would be. We currently use Veritas 9.1 to backup our servers nightly so NTBackup is not our normal method. I understand that an ERD can let you boot a system if something goes wrong with your hard drive but I fail to understand exactly what it does and what it lets you do. Also, if we are using Veritas, do I need an NTBackup ERD or is there some equivalent in Veritas?
How often do you create ERDs if ever?
