I recently installed the official LiteCoin wallet on Ubuntu. I accidentally deleted it about 80% of the way through the synch, and reinstalled it, expecting it to resynch. It resumed. My address didn't change either.
So it seems that the wallet data is stored somewhere in the system. Is this safe? I reasonably expect my system to eventually implode, so I will need to backup/export my data somehow.
Where is the data stored, and how do I back it up?
