How to stop a service before executing an ExecStart entry?

I would like to set up a Timer which will stop a service, execute a script and restart the service.
One of the possibilities is to use
Type=oneshot
ExecStartPre=/bin/systemctl stop myservice
ExecStart=/usr/local/bin/myscript.sh
ExecStartPost=/bin/systemctl start myservice
Another one is to have myscript.sh handling the whole thing, including systemctl.
I find it awkward, though, to use systemctl within a service declaration, when there may be systemd built-in mechanisms to interact with services. Is there a cleaner way to perform these operations?

Can you give more context here? Why do you needmyserviceto be stopped during the run ofmyscript.sh? There's nothing essentially wrong with usingsystemctlinside a service (and you probably won't find a solution that doesn't involve using it), but perhaps, depending on whatmyscript.shis doing, you could just hook it intomyservice.servicedirectly (in anExecStartPre=, perhaps checking if it needs to run) and then just having the timer launch asystemctl restart myserviceinstead... Just an idea. Having more context on what you're trying to do would help here.

@FilipeBrandenburger: this is a Timer which will perform a backup. The service backed up needs first to be stopped, then restarted afterwards.

By (ab?)using the WatchdogSec the service will terminate when it fails to acknowledge within the time. It will then restart, but execute the script first.
WatchdogSec=interval
Restart=on-watchdog
ExecStopPost=/script.sh
ref: WatchdogSec
Having the service being able to be backed up while running would be a much nicer service.
