Backup options for VMware
Posted on 2011-05-07
I am in the early stages of migrating my client from a single SBS2003 Server to a virtual environment which consists of:
2. Exchange 2010
These will all be VM's on Windows 2008 Std R2, and the VM Package is Vmware Essentials.
All storage will be held centrally on an iSCSI SAN. This SAN box also runs Starwind Enterprise CDP Edition which effectively virtualises the storage.
Another SAN and Essentials Plus will be a future upgrade to unlock more DR and HA features.
The current backup solution is by means of Online Backup with a local appliance storing a local copy. Data is also compressed, right now they are using around 100GB (compressed figure).
This is obviously expected to grow in the future.
So, what are my options to ensure a good backup/recovery system with VMWare?
I can keep the existing solution to backup data/email etc.
What else should I be considering?
o If a user deletes something by mistake, I can restore easily using the current backup system.
o If a physical server fails, I can bring up the VM's on alternate Hosts with a cold migrate. No Vmotion so cannot be seamless.
o If the SAN fails, they're screwed. Will need to acquire new hw and reinstall everything.
o If they have a site failure (fire/theft/whatever) only the Data will be recoverable...everything still needs to be reinstalled from scratch
The simplest solution is obviously a DR site but what will not happen til next year earliest, which will have another SAN and probably some ESX hosts and replication.
From what I can think of, it seems to me I should keep the existing solution for data backup and find another solution for backing up the VM's OR maybe the Starwind images (which contain everything)?
