Use a bind mount instead. After you copy what you need to your new
mytharchive directory, add a line at the bottom of /etc/fstab:

/directory/on/big/disk /var/lib/mytharchive none bind

where the /directory/on/big/disk is the path to the directory that you
copied mytharchive to.

Then, at the terminal, do

sudo mount /var/lib/mytharchive
mount

You will see a line in the output of the second command showing you that
/directory/on/big/disk is mounted at /var/lib/mytharchive.

By putting this in /etc/fstab, this bind mount will be done at every
boot, and there will be errors at boot if something goes wrong
(i.e. early). Symlinks will only reveal errors when you attempt to do
something (i.e. too late).

That's my 2c.
