Will Time machine backup the data that I create in Windows Applications running under Parallels? I am running Quicken for Windows under Parallels on my IMAC intel core 2 Duo running OS x 10.5.1

IMac, Mac OS X (10.5)

    No, Time Machine will see that your entire multi-gigabyte virtual machine -- which it considers a single enormous file -- has changed, and will back up a new copy of the multi-gigabyte file every time it sees the slightest change in the VM. This is a Very Bad Thing, if only because it will rapidly fill up your backup disk, perhaps even within hours if you use Parallels regularly and have a large VM.

    Future versions of Time Machine may well include a preference setting allowing the user to change the backup interval from one hour to, say, one week. For now, however, the best thing to do is exclude the Parallels VM completely from the automated backup using the Time Machine preference pane. You can then back up the VM manually to the same external volume as you see fit.

    Exactly what Parallels folders or files do you exclude from the backup of the VM? Or do you just select the entire Parallels folder? What is the path on Finder?

    The Finder path is up to you, wherever your Parallels VM resides. Mine is in my Documents folder, inside a folder called Parallels. I exclude the entire ~/Documents/Parallels folder and back that up manually once a week. (Just be sure you're not excluding your whole Documents folder!)

    Thank you.

    Can I tell time machine to back up only my Quicken files within Parallels or can I only exclude all of Parallels?

    The other poster explained this - your quicken files and anything else in the Parallels virtual environment exist in one giant virtual hard drive file. Time machine sees one file, be it 5 gigs or 10 gigs or whatever. It's not a real hard drive, but acts like it *in the context of being in Parallels."

    To back up important files while running a Windows virtual machine, use backup software inside the windows machine - just as if you were running a real windows computer. You can use one of the free online storage services, or copy backups to a CDR, or to a keychain drive. I suppose you could also copy your Quicken files to your Mac desktop, so that when time machine does run, it will then see the individual quicken file as belonging to your Mac OS.

    I have this problem. I have crashed my QuickBooks in Windows XP in Parallels and am trying to figure out how to restore it from Time Machine.

    I tried restoring the Parallels desktop from Applications but that didn't seem to work. I'm reading about the .hdd file and the VM file. Eric said his VM is in a Parallels folder in his Documents - mine isn't.

    I understand I have to restore the whole VM but I'd love to know how to find it.

    Any help out there?

    use spotlight to find winxp.hdd. It should be in 'documents', but look for a parallels folder in applications, too.

    By default your folder with all files belonging to one Virtual Machine will be at yourhomefolder_name:Library:Parallels:Virtual_machinename
    Good luck!
