I have Intel Desktop Board DP965LT with Seagate 750 SATA HDD installed on ESXi 4.1. which is up and running.
4GB RAM and Core 2 Quad Q6600 processor.
My worries if that hard drive would fail, how can I image or mirror that hard drive?
Planning to run at least 4 guest OS.
Hope you could help me
Thanks in advance!
Since you don't seem to run a cluster or a centralized storage to protect against harddrive failure the only redundancy option would be a raid system with several mirrored hard drives in the server. This how ever does not eleminate the need for a proper backup since it only protects againt hard-drive failure, not against data-loss within the VMs. Another cheap option would be a low-cost iscsi storage system with raid protected disks. But again, even if you protect the dicsc, you will need a proper backup solution which enables you to restore everything in case the data gets destroyed.
You could add your NFS export as a datastore and copy the .vmdk files over to that one on a regular basis. Maybe you can use scripts to quite the base volume (snapshot), copy it over and commit the snapshot.
If you're using the free edition of ESXi you won't be able to use vCLI to perform commands. It is limited to read-only.
