You do not loose anything.

you have to understand what mounting means. You mount a filesystem to a directory, and the directory will become the new filesystem (in your case the external harddrive). All contents below the mount-directory (in your case var) will not be accessible until you unmount the harddrive.

Why in the first place do you want to mount something to /var?

normaly you mount something to /media/<something> or /mnt/<something> .... the logic of mounting something to /var eludes me in the moment.

If there is a real reason to mount to your /var please state your requirements for doing so.

Hatrix76 explained why your stuff is not accessible when mounting external HD to var.

If you want to keep your external HD mounted to var and still have the stuff in var accessible, you will have to move all the stuff in var to your HD.

So mount your external HD to /mnt/exthd (or whatever floats your boat)

Then move everything in var to /mnt/exthd

then unmount /mnt/exthd and remount it at var like you want.
