back to article Luminex rips virtual tape from data centres, shoves it in the cloud

While EMC thinks the next move in storage is to rip the tape out of the mainframe and replace it with the virtual stuff, Luminex seems to be going one step further: by grabbing its virtual tape from the data centre and floating it up to the cloud. Mainframe virtual tape library (VTL) vendor Luminex has buddied up with cloud …

There is NO BACKUP in the CLOUD, ONLY VAPOR

A backup is a complete copy of your data, with incremental updates on changes. The minute the responsibility for the back up job and the actual data leave your hands, it's reliability percentage drops like a stone.

A physical backup (Tape, Optical or Hard drive) provides 100% certainty if you do it yourself and check the results.

That cannot happen in the "Cloud".

Indeed. Will the Cloud ever be as reliable and secure as a hard drive sitting on my shelf (or even in a safe)? Somehow I think not

If that shelf is in the same building as the server it is backing up, then it doesn't protect against some of the hazards that could affect your data, such as fire, flood, physical theft and so on. A cloud backup, being off-site may provide better protection. It is a good idea to have both.

Sure. That's why enterprise grade backup procedures call for multiple backups and multiple copies and rotation of backups to offsite locations. This has been standard practice since long before the current crop of buzzwords.

Low level replication of storage between multiple data centers is also pretty mundane.

Any company that has a good enough network pipe to make backing up directly to "the cloud" even feasable likely already has such accomodations in place already.

Hmm...

I'm in two minds, clearly this is just applying the word "cloud" to a rented virtual tape library in a third party datacentre, as with any outsourcing deal there are good ones and bad ones, if you do the due diligence properly you should be ok.

However, backup hardware in another site to the machine that it's backing up tends to require a lot of bandwidth, which is expensive. You have the advantage of instant off-sitedness, but the cost is high. Most companies who already require this sort of functionality already have it in place. There is, of course, a possible bonus - if they have a few zServers on site, that you can recover to as required that would be attractive for sites which don't have dual datacentres, but still need mainframe.
