In the past I routinely backed up my entire unencrypted /home folder with LuckyBackup (gui for Rsync) to an external HDD. I've had no problems seeing and manipulating the backed up data when accessing the external backup HDD from a LiveCD, another Ubuntu computer or even Win7.
I recently installed Ubuntu 12.04LTS on a new SSD and decided to enable /home folder encryption during installation. Now, when I do a backup of /home to my external HDD using LuckyBackup, I can only see the backed up data on the HDD when I am in logged in to Ubuntu 12.04. When I try to look at or manipulate the data from a LiveCD, another Ubuntu computer or Win7 the data is not accessible and has a user 1000 permission set which can not be changed.
I conclude from this, that all of my backed up data is now saved on my external HDD in encrypted form. I did not expect this, nor do I want it. I want the backed up data saved in unencrypted format so I can access it from other OS's.
Question: Is there a way to backup an encrypted /home partition's data in an unencrypted format, read/copy/executable by any other OS?
