    I want to create an encrypted container to store sensitive data on my mac. The problem is I would also like to have the ability to backup that data. The container I was thinking about making is about 20gig.

    The backup I use is external harddrives. They are formated with FAT so that I can "float" them between windows and mac. Since they are formated with FAT I can not put a 20gig file on it...

    Any Ideas?

    I was thinking about:
    1) An encrypted container that breaks up on 2 gig chucks (can not find SW that does that)

    2) A file system other then FAT that can be shared between windows and MAC, that I can put on my external HD...
    a) NTFS (Windows support, not MAC)
    b) MAC FS (No windows support?)

    NTFS-3G allows OS X to read/write to NTFS (Windows) and it is free

    MacDrive allows Windows to write to HFS+ (Mac OS X) but it is not free

    There's 3rd party apps that allow Mac to read and write to NTFS such as NTFS-3G.

    Speed

    When using these do you get the native speed, or is there a penalty?

    When moving big files will it take a long time?

    I have not noticed any problems with NTFS-3G

    I move files all the time from ntfs formatted external drives to my mac. I have them formatted like that so I can "float" them between mac and pc as well, i just have ntfs-3g installed. Ntfs-3g is a great driver and I have noticed no speed decrease when copying files to ntfs formatted drives. I would use ntfs-3g and format your drives as ntfs.

    Speed tests

    I wanted to get a better idea of the speed, but didn't want to format my disk yet. (Have to move lots files for this, and not ready yet)

    So I moved one of my video files it was about 2.23gb, the baseline it took about 1.5 minutes. Then I created a truecrypt volume that was 3GB and moved the file into there (note the volume was on my external drive) and it took about 2.0 minutes. Finally the test of interest I created another truecrypt volume and formated it with ntfs and repeated the same copy. This test with the ntfs took about 3.5 minutes. That means there is a penalty for using NTFS which appears to be somewhere in the neighborhood of about 1.4x or so...

    You guys do not notice this delay?

    I like the "free"ness of it, but I plan to keep 100s of those size files in sync.

    No, I haven't noticed any real issues with speed or file transfers
