Running Asigra Televaulting on CentOS 4
Jan 17th
I’m setting up a VM on my VMware server to manage network backups. Asigra Televaulting is an agentless backup client that stores the data on offsite disk rather than on tape or local disk. Your backups are pretty useless if they burn up in the same fire that destroys your PC. The idea is for the VM to be in suspend until needed, thus not impacting performance of the other VMs. A command in the crontab will resume the VM in time to hit the schedule. I’ll then use Asigra’s pre/post job scripting functionality to suspend the VM when the backup is More >

It kinda blows when I’m in the middle of nowhere and my Nokia e61 can only get a 14k GPRS connection and have to wade through all my mailing list chatter. Server side filtering is the way to go and Procmail is the tool for the job…
Installing it on Debian is a 2 liner if you read this page. “apt-get install procmail” and adding “mailbox_command = /usr/bin/procmail -a More >
Adventures in virtualisation
Jan 12th
And it continues…… Xen would be nice, but XenExpress’ hardware support isn’t perfect. I realise that it’s a bit much to expect it to support my wi-fi hardware, but it would be nice. Xen is a paravirtulisation solution. It usually uses a custom kernel for each “guest” machine to translate it’s direct hardware interaction into interaction with the virtualisation “engine”. The upside of this solution is that the virtualised servers run almost as fast as if they were running on bare hardware. The down side is that you cannot run closed source operating systems (unless the OS developer supplies a Xen compatible More >
