Hey Ski, Care to elaborate a bit more on that carrot you just dangled? I would love to see a website of actual business-case examples utilizing BackupPC. Is there such an animal, anyone? Thomas, are you at liberty to describe your setup in more detail? Can you mention expected costs? Are you or anyone else using SSDs such as the "Violin 1010"? Thanks. -obj Ski Kacoroski said the following on 04/08/2009 12:27 PM: On Wed, 2009-04-08 at 15:28 +0200, Thomas Karcher wrote:Hi,This is probably the wrong place to ask, but people on the right lists won't have experience with the kind of disk activity that backuppc creates. I have my main backuppc server set up so I can periodically swap and raid-sync a new disk and keep a copy offsite. I'd like to have a VMware/virtualbox or other virtual machine image that could run on any machine that would be able to access this disk via a USB adapter for quick emergency restores. Does anyone have experience with any of the virtual machine's USB handling to know if this would be practical and which technology would be best at it?I don't know if it's best - but I run backuppc inside a Xen VM productively on a device that is forwarded via nbd (network block device). It's quasi independent from the actual underlying storage type and can be accessed over the network, since you don't necessarily have to plug the USB disk into the VM's host machine. Performance is of course not really great but surprisingly good. I evaluated (very shortly) against mounting via NFS, and NFS just sucks with backuppc.Thomas, I think it depends on the NFS server you are using. I have over 1500 clients backing up via 7 backuppc servers attached via nfs to a high performance Exastore NAS device. Works great. ski |
