How do I determine what size to make the target encrypted disk image?
The source User folder is 33.37 GB but the mounted disk image itself, which was created from within SD, is 130.73 GB (96.94 GB available). If I use Get Info on the unmounted disk image, it's 34.28 GB. Also, when backing up, should the source disk image be mounted or unmounted? What about the target disk image?

You should make it the full capacity of the source drive, since that's the largest it could become.
You'd have to ensure the source is mounted. The destination's password needs to be in the keychain, and it should auto-mount.

Sorry to be a little confused--is there a reason the target image needs to be so much larger than the User folder itself? (It's a backup archive; I won't be adding to it later.)

Much, no. Larger, yes - you'll need some working space.
But "empty" space in a bundle, especially if you only use it once, doesn't create a significantly larger file. It's a virtual disk.

If I were creating a hard-drive partition for such a backup, I would think 50 GB or even 40 GB would be fine? David P.S. On reflection, I now realize that SD may have created a 135 GB sparse bundle because the original source volume was 125 GB (with about 78 GB used). Last edited by DavidCB; 07-05-2011 at 02:47 PM. |

Correct. We sized the bundle based on the size of the source volume. You decide how big you want it, David: I think I've given you my thoughts...
