There's a chance of recovery, but it diminishes every minute the server runs. I hope you've shut it off since you've deleted the directory.
Relevant Skills and Experience
I've done plenty of data recovery on linux and Windows machines, over the years.
Proposed Milestones
₹4000 INR - As much as possible of deleted folder recovered.
The bid is for the time to grab whatever is there, since I cannot guarantee what's recoverable.
