BE2012 - Design/strategy - VMware based with GRT OR regular backups with periodic VMware backups
I am setting up a new environment, based on Backup Exec 2012. We have Backup Exec licensing for VMware for all hosts and application/database license for all AD, Exchange, SQL, Sharepoint servers.
Our environment is almost 100% virtual - based on VMware vSphere 4.1. Around 50 servers and roughly 2TB of data. We have Exchange 2010, Sharepoint 2010, SQL server 2005/2008/2008 R2, Active Directory (DC's running 2008 R2). We have shared storage based on Fibre Channel and the backup server is connected to the shared storage through FC HBA's
Now, I am a little unsure on how I should make this setup - should I base the setup on a pure VMware backup, and use the GRT option to allow restore of AD, exchange, SQL, sharepoint objects, OR should i perform "regular" backup of AD, exchange, SQL, sharepoint servers? What do people do and what are their experiences on the various choices for backup strategy and agents?
I have personally thought of running a GFS rutine with daily differential and weekly/monthly full backups, based on VMware backups - D2D2T
But I need some inputs on Best Practice, pros/cons as well as maybe other suggestions for strategies...
Any help is greatly appreciated !
