Q - Restart from backup - Restart your palace server with a backup copy of your pserver.prp file
This utility does two things. First - it puts in the backup copy of your prop file (assuming you have one). Second - it attempts to resart your palace.
Use this utility if you cannot get your palace to start and you have a backup copy of your prop file (see the FAQ on prop file maintenance).
NOTE: Give this utility a few minutes to work. Your backup prop file is stored in a compressed form to save disk space and it must be decompressed before you can use it. If your backup prop file is large, it can take a few minutes for the server to decompress it from the backup and put it in place.
