Re: Bootable external encrypted backup

This issue has been solved. See solution.

Hi,

I am referring to a post with the same title from the PGP Whole Disk Encryption for Macintosh forum from March 31, 2010. I'm having the same issues that the external drive that I WDEd first and then cloned my system to using CCC does not boot. I'm using a 250 GB external disk, my internal disk is 500 GB. My question is, does this have anything to do with the size of the external disk? The last person in that post didn't seem to have had any problems booting from an external drive and wrote:

"Duane - per your last, I can confirm that WDEing the external first and then cloning without /PGPWDE01,02 works just fine.  I can successfully boot the external, and it's only after OSX starts that I'm prompted for the internal password.  Using a FW800 external 500GB disk (same size as internal), CCC 3, incremental mode, preserve root items on target."

Does it require a bigger external drive to make an encrypted bootable clone? Should it be the same size as the internal drive?

Nope, drive size isn't the issue.

Did you manually exclude the /PGPWDE01 and /PGPWDE02 files, and choose 'preserve root level items on target'?

Hi,

Thanks for replying. No, I didn't. I thought that doing the incremental mode and choosing 'preserve root level items on target' should be sufficient. Obviously, I then have to deselect the two root files manually. Where do I find them, what is the path? In any case, my internal drive, that I want to clone to an external WDEd drive, is not encrypted, so these files shouldn't be there, right? Or are they created when I just launch PGP on my home drive? Thanks, again.

If the internal is not encrypted, then they won't be there, and it's not an issue (they're in /).  I remember some reports that clones to USB disks had some issues (mine are firewire), so that might be what you're running into.  Otherwise, it should work (does the drive show up when you hold down the option key prior to the chime?)

Yes, it does show up. After a booting attempt I get the a cirlce with / in it. Same as was described in the earlier post. My next step was to try a firewire drive. I think that is the answer.
