![]() It is worth considering if you need regular backups of ongoing work on the VM, but since you say you don't care about changes to the VM then snapshots are best avoided altogether. ![]() Snapshots affect performance quite a bit unless the snapshot and the virtual disk is on a high-performance solid-state drive. You could "backup the VM using time machine once, then exclude the folder that contains all the VMs" but the Time Machine interface is not the best for retrieving your saved copy in that situation, plus Time Machine will delete old files if it needs to in order to save space and you don't know when it will delete your one and only backup copy of your VM.īy doing a manual backup of your VMs you can also refresh them once in a while (say when new guest OS updates are applied) much more easily than with a Time Machine solution. Make sure you give Sun VirtualBox a try too - its free and I think it. You will eat up all your storage space very quickly and it will be pointless anyway. The programs behave fairly well within either application (Parallels or VMWare). I've heard Parallels and Fusion are better, although I've never actually used them. VirtualBox is pretty slow, to the point where it's frustrating to use. ![]() ![]() Letting Time Machine "do its thing" is a bad idea, as it will make a new copy every it does a backup, which is generally around once an hour. VirtualBox is good enough for Linux distros, but if you want good performance VMware or Parallels are the way to go. I keep a copy offsite on a portable RAID 1 drive.
