It depends on how your app is using it. If it absolutely requires the
data to be in memcache, then yes. If it supports falling back to the db
if it doesn't find it in memcache (and then adding it to memcache), then
no - your app will re-populate memcache as it needs to.

You'll need to write your own script(s) to do this - memcache has no
idea what you want to cache (so there's no "auto sync" type script).
