Aren't there solutions to this already? INotify based sync daemons (or
even just a cronjob)?
Although if this was implemented in PVE there could be a status
message and a progress bar somewhere in the UI I suppose.
Maybe there's an acceptable already-packaged solution which has a nice
interface to get the status and/or start/pause the syncing.
