If you're just using this disk with Linux (or certain other Unix-like
OSes), then ext2/3 would be the way to go. But unless this disk came
formatted NTFS, I suspect there's a Windows machine in the mix. And
Windows just doesn't understand filesystems with symbolic links.
In this case, your best bet is probably to back up the areas that do
need symbolic links with tar (e.g)
tar zcf /media/usbdisk/linux-backup.tar.gz /path/to/Linux/area
One other thing: I presume that when you say "internal symbolic links"
you mean they're relative. A good example is /usr/tmp on a Fedora
system:
ls -l /usr/tmp
lrwxrwxrwx 1 root root 10 Jun 29 2005 /usr/tmp -> ../var/tmp
Notice that /usr/tmp points to var/tmp in the parent directory, not
directly to /var/tmp. If /usr was ever mounted anywhere else (for
example, for rescue purposes, or under another Linux distribution), then
/usr/tmp would still point to the Fedora /var/tmp directory (or into
thin air if /var hadn't been mounted), not to the "host" OS's /var/tmp.
In your case, relative symbolic links will continue pointing onto the
USB disk if it ever gets mounted under another name or in a different
tree.
Hope this helps,
James.
