Yeah!! Its World Backup Day today. Get more details at http://www.worldbackupday.com/. I wonder sometimes how they have a day for almost every minor thing we have in our lives and virtual-lives. Backups are important, do keep backups of production machine, development and any other machine that you will regret loosing of later. You can either get a backup service from one of the many providers or buy a cheap dedicated (with say ATOM processor) to rsync data there, either way, Do keep backups, you won't regret it. There is an interesting discussion going on at LowEndTalk, do read the thread when you have time time.
Today, I was sad to read the post on my favourite blog lowendbox.com (LEB). I discovered LEB a few years ago and it has helped me learn a lot and try out many different VPS services all under $7/mo. But finally the blog anonymous blog author of LEB whom we call Low End Admin (LEA) has announced that this blog is taking a lot of his time hence he may be selling or giving it to someone who can run it at least as good as LEA himself. Its a sad day Indeed!
Someone pointed out a shocking fact in LET that KVM, the new popular virtualization type, can be over-committed even more then the infamous OpenVZ The KVM hypervisor supports overcommitting CPUs and overcommitting memory. Overcommitting is allocating more virtualized CPUs or memory than there are physical resources on the system. With CPU overcommit, under-utilized virtualized servers or desktops can run on fewer servers which saves power and money. Read it all at docs.redhat.com also read the complete thread at LET Is KVM the next oversold VPS? for more enlightenment
