Impossible to create snapshot

Installation Home Assistant OS

A couple of days ago the snapshotting functionality was working perfectly as expected. This morning I tried to create a new snapshot and got the following error

19-09-22 08:02:24 INFO (MainThread) [hassio.snapshots] Full-Snapshot 54301965 start
19-09-22 08:02:24 ERROR (MainThread) [hassio.snapshots] Snapshot 54301965 error
Traceback (most recent call last):

    self._tmp = TemporaryDirectory(dir=str(self.sys_config.path_tmp))

    _os.mkdir(file, 0o700)
FileNotFoundError: [Errno 2] No such file or directory: '/data/tmp/tmpoiexjx0l'

I restarted HA, rebooted the Pi, etc but I keep getting this message… Anyone has a solution ?

Anyone has a solution besides reinstalling everything with an old snapshot ? And try to see if it works again ? I do not have any other idea…
