Thanks for all the responses. I would have preferred to use something
besides FAT32 for the backup disk, but it's going to be shared between
several machines, some Linux and some OS X, and FAT32 seems to be my
only choice for something that both can read/write.

I would like to use duplicity to backup my home directory to a USB
disk, formatted FAT32. If I do:
duplicity $HOME file:///media/usbdisk/target_dir
will I run into problems with FAT32's 4 GB file size limit if $HOME is
larger than 4 GB? I ask because of the statement on the duplicity
home page that says "Duplicity backs directories by producing
encrypted tar-format volumes...". Does duplicity create a single tar
file containing the entire backup?
No, duplicity creates multiple volumes of 5MB each (default), so that's
not a problem. However, to work with FAT32 file systems, you will need
to use either the option '--short-filenames', or '--time-separator=_'
since the colon in the filenames is illegal on Windows-based
filesystems. I would suggest the second option for readability.
