Less known Solaris Features: Point-in-time copy with AVS

Sunday, April 27. 2008

Okay, the next installment of the "Less known Solaris Features" series is online. This time i will discuss the feature Point in time copies with AVS. As i have to go through some theory at first, it´s a quite long tutorial. It´s the longest so far. Point-in-time copies are a rather unusual feature for small installations, but they are absolutly essential for many enterprise customers. And when you really think about it, there are many usecases even for small installations.

Have fun while trying out the feature!

Thanks once again for these great tutorials. Is AVS part of Solaris standard installation? Is there a seperate license necessary?

I know this topic from storage vendors, e.g. EMC with timefinder products or Netapp with snapvault/snapmirror products. There you can do all of this stuff without presenting all devices to a host with storage internal copy mechanism. But you have to pay extra for this features. Copying is not done by the host in that case.

What are the main differences between AVS and storage based products?

AVS isn´t part of the Solaris 10 standard installation. You have to buy an extra license. But AFAIK you can download the product and test it for 90 days.

You have to pay for it. It isn´t cheap, but as far as i know it´s much cheaper than the products from storage vendors.

The main advantage of doing this on the host, is the fact that you are independent from the hardware, for example, making a remote mirror from a expensive HDS to a cheap storage ... (or vice versa)
