backupwallet command must be supplied with destination file.
sunny> ppcoind help backupwallet
backupwallet <destination>
Safely copies wallet.dat to destination, which can be a directory or a path with filename.
Directly copying wallet.dat is not a 100% safe backup. The copied file may not be flushed, thus restoring could fail with database error in db.log.
The .dat file does not seem to be showing up when I do something as simple as:
ppcoind backupwallet C:\walletbackup.dat
Ideas?
