Partitions & Backups in VMWare?
Posted on 2007-07-24
We are planning our VMware virtualization project early next year, but there's one thing I still can't get my finger around:
On a Physical Server, you have multiple arrays, for OS, Logs, Databases, etc. but when you virtualize that server, you get one huge flat file. How does one go about seperating the partitions so that they aren't on the same volume. (Or to put it this way, you seperate logs from databases to ensure that you do not have a total loss if one of the arrays dies, but in a VMware, you don't have that type of protection, right?)
With regards to backups, I know that there doesn't exist a Mass Market (Read:CA,Symantec, IBM) 3rd party agent that can backup VM Server images while they are running. Is there ever a plan for them to be made, as VM seems to keep exploding in popularity, etc.
There are two options to backup VMWare images currently:
1)Stop the Server, copy the flat file, then start it again; Not a very clean option since some of these servers you wouldn't want going down for even a copy, especially with their size.
2)Use the VMware Aware Software backup software (which is the best one?) to backup the images.to a NAS or SAN.
Obviously in both cases you would have the Windows Agent in the vmware servers to backup the individual files.
