If you used TrueCrypt for this, it would not have to work on top of a |
16 |
file system. It is possible to have TrueCrypt operate with an entire |
17 |
partition and not an encrypted file system image sitting on top of (say) |
18 |
a FAT32 file system. |

In TrueCrypt v6.0a, you would do a Volumes -> Create new volume -> |
21 |
Create a volume within a partition/device -> Standard TrueCrypt Volume |
22 |
-> /dev/your_usb_drive_here and then format it with your file system of |
23 |
choice (go ext2 if you're comfortable with using the Windows driver that |
24 |
implements it; I'm not, but that's my damage). |

If it's read only and you want to back up data from your Windows install |
30 |
as well, you're going to find that problematic. |

You could do that if you wanted and use one partition for Windows stuff |
37 |
and one partition for Linux stuff if you wanted to. My concern would be |
38 |
how big a partition you'd need for Windows stuff and how big a partition |
39 |
you'd need for Linux stuff. I don't think that it would be easy to |
40 |
rework the partition scheme in case the amounts of data were different |
41 |
from what you were expecting. |

What I wound up doing for one of my boxes was mounting the Windows |
47 |
partition inside of my Gentoo install when it came time to back up, |
48 |
backing it up under /mnt/backup_drive/windows when I ran my rdiff-backup |
49 |
script, and unmounting everything at the end of it all. I eventually |
50 |
gave up doing that and bought a separate drive for the Windows |
51 |
partition, and encrypted all disk devices concerned with TrueCrypt. |
