preventing rsync transfers

[Peter]

I sync some client stations to a central server at the discretion of the
users.  They run a single-transfer daemon by logging in via their ssh
accounts.  All is well.

Now I also allow a certain user to rsync this accumulated client data
(which end up as subdirectories of a single directory on the server) to an
external hard drive.  This user connects via ssh and runs a remote shell
script on the server.  (The script is needed to manage rotation of backups
and to make sure the drive is mounted/unmounted properly.)  All is well.

Now I'm thinking: What if these operations overlap?  What can I do to
prevent this?  Or is this even a problem to begin with?
