Basically a very simple setup, but have eluded me for some time now: Simply backup some running VM's on a ESXi 5.x to a FreeNAS NFS service. I'm running FreeNAS 8.2 (FreeNAS update routine is also give me some strange access rights errors lately, so never got round to updating the bugger) Shouldn’t be a problem with version 8.1 or 8.3.
Things might be done differently with better preference/lesser work. I'm no expert, so please let me know if your setup performs better, or to point out some stupid mistakes I have made. But the following will get backups of your VM's to a FreeNAS box.
I'm still struggling with some kind of synchronisation with Amazon S3 from FreeNAS. If you have done any kind of progress along offsite sync from FreeNAS or any throughs on this, please let me know.
All glory is going to William Lam (www.virtuallyghetto.com) for his work on ghettoVCB script. There is nothing original here, I just put some snips together.
