RAID Backup
Saw this article and recalled some of our threads here about RAID and Backup and such. This is a great example of how RAID Backup, of how data on RAID arrays (even mirrored ones distributed world-wide) can be destroyed, and then your only recourse is to have a good backup -- mag tape in this case. http://techcrunch.com/2011/02/28/gmail-failure-2011/ http://alum.wpi.edu/~trb/wcarols.html#mag - Dan. -- - Psychoceramic Emeritus; South Jersey, USA, Earth. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

And thank god they do. The minions at Google, despite any other failings, remain Very Smart People. They're not dumb enough to fall for the magical unicorn fart cloud hype; they know that 'the cloud' is just a fancy file server with http:// access. I do wonder how many metric tons of tape they buy every year, tho, and how many of these they're buying: http://www.oracle.com/us/products/servers-storage/storage/tape-storage/t1c-drive-ds-289750.pdf (Current world champeen tape backup system...5 Tb per tape, uncompressed, you can buy a 1 exabyte backup library from them...1 million terabytes. This is the kind of thing that keeps Larry Ellison in Yachts and MIG's...) -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

It would be interesting to see more details - HDs, tapes, and power. Betcha they use more power world-wide than some countries! - Dan. -- - Psychoceramic Emeritus; South Jersey, USA, Earth. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
