Don't backup your data by straight copying to FAT. Rather tar-zip which
will preserve your file permissions/attributes and also compress the
stuff.

NTFS is not that bad. It supports ACLs which linux does not yet. The
biggest problem is that very few Windows (NT) users know/care about file
permissions.

The access control is not significant. If you mount a partition in one
OS from another OS, you can normally override file security. If you have
tried the Ext2fs reader for windows, you will see that you can extract
ANY files you like from the file-system, without a unix account !

What is more significant, and the actual problem here is the mapping of
unix permissions / file attributes. When linux has full support for
NTFS, this may be solved, since NT has rwx permissions on directories
and files.
