Safepoint - Add feature to mount existing safepoint (and check it) after loss of connection

The reason for this, is that WDMYcloud sometimes loses connection and the safepoint. For example, my safepoint is on another machine which is powered down (except for backup times). Sometimes for no reason it can not find the safepoint which is there on the network and share that it just scanned. The safepoint is there on the share that it found but it cannot see it.

Allow us to use/mount existing safepoint, if it is corrupt fine, create a new one if not then mount it.
