Could you help me with clarifying what do I need to do if the VMware vCenter Server or the database will crash or be corrupted and I need to do a disaster recovery to get vCenter Server up and running?
With a good backup of the vCenter server and its database I can perform restore but if I don't have a good backups what are the options.
If I am unable to restore the server and need to reinstall vCenter and configure it from the ground up.
For example if I have only backup of the database, but I am not able to restore vcenter server.
what exactly is stored in database?
I read this article http://www.yellow-bricks.com/2010/08/09/standby-vcenter-server-for-disaster-recovery/
and there is written that roles and permissions are stored in ADAM so in case of problem and not ability to restore, it seems that I will lose roles and permissioonns.
Currently what I am doing is: 1. backup database every day. 2. backup vcenter as a whole vm to tape, and recently due to library crash I lost several tapes and backup of vcenter were on this tapes.
is there anything else that I need to add in my backup strategy( for example ADAM backup and maybe how to do it or anything else that I am not aware.
You'll need to make sure to backup the certificate file that vCenter is using in order to restore it correctly.
How big is your enviornment? Depending on the need and if you have spare resource you could always setup another vCenter. The secondary vCenter will be automatically promoted in the event of primary vCenter failure. To cut the cost you could use vCenter Appliance for the secondary vCenter.
