I created 50 small (1GB) encrypted DMGs using DiskUtility, and want to combine them into a single 50GB "virtual" drive but still have 50 1G images on disk. How? Why:
I want to encrypt my files (even the filenames) before backing them up without using half my disk space just for encrypted files.
I use an external backup service that'll backup 1G disk images
(files), but not 50G files. The smaller the individual disk images, the better.
I'm running Mac OS X 10.4.11, so I can't use cryptomfs (plus, I'm not sure if cryptomfs creates several small files or one large file). I have MacFUSE installed, so I tried installing cryptomfs anyway, but it failed (both 1.0 DMG and 1.1 pkg file).
Since upgrading is neither free nor easy, I'd prefer to avoid it.
I've considered other options (eg, a directory of hard links to the files with encrypted names for the hard links and relying on my backup service for content encryption), but they get fairly complex.
