Time Machine, Encryption and Backup

Question

Hi,
I am using an encryption software to encrypt some folders of my account (called Kryptospace: http://www.cemacsoft.com/products/kryptospace/kryptospace.html)
So here is the situation:
* In Documents I have a folder called Private, this folder is the mount of an encrypted DMG (Located in ~/Library/Application Support/Kryptospace).
* I have got Spotlight to reference this DMG - which works fine
* By default TM set the folder as Excluded so I removed that from the Preference Panel
* But I noticed that Time Machine does not backup the data within the folder
Do you know how could I get TM to backup this folder, I don't mind if it's not encrypted since the backup is secured (unlike a laptop that I could lose).
Thanks & Regards,
Daniel

Daniel,
As long as Time Machine is backing up the disk image, itself, it is keeping your files backed up. The only problem with this scenario is that the entire disk image file must be re-written during every backup for which files inside the disk image have changed (the disk image file will have been modified, so a new, complete copy is backed up). This is less efficient from the standpoint of disk space usage.
What I have posted above will hold true, as long as the third-party software doesn't do something odd with the disk image. You are aware that there really is no need to use a third-party solution to do something that OS X, by itself, can handle quite well? You could create your own encrypted disk image using Disk Utility, store it somewhere convenient in your HOME folder, then create an alias that points to some location inside the disk image, and the results would be the same. If you included the key (password) for the image in your Keychain, access from your account would be seamless and transparent.
