There is a bug with the way NetWorker 7.5.2 handles ADV_FILE devices in relation to disk evacuation. I.e., in a situation where you use NetWorker 7.5.2 to completely stage all savesets from an ADV_FILE device, the subsequent behaviour of NetWorker is contrary to normal operations. If following the disk evacuation, either the standard overnight volume/saveset recycling [...] As I mentioned in an earlier post, EMC have announced on their community forum that there are some major changes on the way for ADV_FILE devices. In this post, I want to outline in a little more detail why these changes are important. Volume selection criteria One of the easiest changes to describe is the new volume [...] With their recent acquisition of Data Domain, some people at EMC have become table thumping experts overnight on why you it’s absolutely imperative that you backup to Data Domain boxes as disk backup over NAS, rather than a fibre-channel connected VTL. Their argument seems to come from the numbers – the wrong numbers. The numbers constantly quoted [...] Everyone who has worked with ADV_FILE devices knows this situation: a disk backup unit fills, and the saveset(s) being written hang until you clear up space, because as we know savesets in progress can’t be moved from one device to another: Honestly, what makes me really angry (I’m talking Marvin the Martian really angry here) is [...] As you may have noticed, I have a great deal of disrespect for “tape is dead” stories. To be blunt, I think they’re about as plausible as theories that the moon landing was faked. So I thought I might list the criteria I think will have to happen in order for tape to die: SSD will need [...] Over at SearchStorage, there’s an article at the moment about using NAS disk as a disk backup target – i.e., where (in NetWorker), the ADV_FILE device would be created. I have to say, I strongly disagree with the notion of using NAS mounted filesystems for disk backup, even if NetWorker lets you. In short, it’s a [...] Or, “In 5 years time will we reflect on VTLs as an example of a bad direction in data protection?” Introduction Many people are convinced that VTLs are the bees knees – they offer backup to disk while still working within the bounds of a tape library (or libraries), are frequently considered to be “easier to conceptualise”, [...] |
 @prestondeguise shows IT pros a simple way to forecast growing data needs http://bit.ly/aWiw9H
6 hours ago If Telstra employed the same personalities in their complaints department as they did in all other departments, I'd never need to complain.
17 hours ago @mariekehardy No, he's still misquoting Highlander. I believe he's up to the TV series now... :-)
