Unfortunately deleted means deleted. Data gone.

My recommendation is to use it as a reverse proxy to expose services but ultimately host from another device.

It's 1 gb of ram anyway (the free 24 gb of ram arm vps' are scarce and hard to get).

Another tip is that they monitor cpu and ram and are more likely to delete it if is idling. There exist programs on github that do nothing but waste cpu in order to try to keep the oracle vps up.
