back to article C'mon, Commvault: You have the tech to build VM mutants...

Commvault, the arch archiver and backup biz, appears to have a virtual machine "mutation" facility, and this has prompted some speculation here at El Reg storage desk. A quick recap. Simpana 10 can back up physical and virtual servers and virtual machines (VMs) from VMware and Hyper-V. It supports cross-platform data protection …

Meh

Always liked Commvault,

Back since they were the best people to do backup for Netware.

The opportunities are immense.

For the NSA to slurp even more of people's data.

How realistic is this in the realworld?

I can't see this feature being rolled out that widespread, without a lot of x86 servers and fast storage to make it happen.

Commvault already needs pretty beefy servers as is (They are not an appliance vendor like EMC) so all processing is done in the MediaAgent typically. e.g. PCI Flash, 15k disk, 32+GB of RAM, etc.

Now you want to take a backup, and then perform an automated P2V, and DASHCopy it? How much more compute is needed to do that in a reasonable amount of time, let alone how many concurrent ones can you do?

Since you're creating an entirely new dataset/stream, how efficient can DASHCopy even be? I fear the bandwidth needed in the manual will say "Dark Fiber required to remote site."

On paper this sounds great. Architecturally (Let alone in a tight RTO), sounds like a nightmare.

Re: How realistic is this in the realworld?

And what is an appliance if it is not just a server running propriatory software?

The server spec you detail is near enough any bog-standard rack mount. What CommVault does with deduplication it light-years ahead of the competition. No one can get any where near it and it is all client side. Network bandwidth and client overhead are minimal. As far as restoring into another cloud provider, you have the same issue, no matter who or what it is unless the remote underlying infratructure supports your backup solution. This is simply the reality of stuffing endless amounts of data into a hosted cloud. At some you will want it back or in a different place and you will have difficulties, vm, data or database.

Once data is over a certain size, unless you have core network bandwidth, you are never going to get out. It has always been and always will be a one-way trip. The big providers know this and are laughing all the way to the bank.

Re: How realistic is this in the realworld?

It´s Real

look at AppAssure, he can do this since some Day´s.

But not only from V2V anso from P2V and vise versa....!

cheers

Re: How realistic is this in the realworld?

LOL. Avamar was doing this circa 2001 or so, you are very incorrect. This is way before Commvault was even a name in the enterprise. Avamar to this day still has the best client-side dedupe performance in the market I've seen against various platforms. It's just cost prohibitive.

An appliance is purpose built for a limited task at hand. Purpose built, and purpose tuned. That cannot be said for Commvault, backupexec, TSM, etc. When PureDisk was around is was a cluster *** to get support, due to all the finger pointing on your own hardware, HBA's, multi-pathing software, etc. Commvault is no different.

I see this happening

With Linux VMs, with Windows not so much.

After all 30 years of obfuscation and intentional complexity will have to take a toll.
