title: Redis is empty after startup, altough there is an .rdb file
body: <p>After I ran "shutdown save" in my redis-cli, waited for the "save" command to finish (followed the redis log) and backed up my redis .rdb file, I tried starting the redis server from the begining and it was started with an empty DB (dbsize =0!!!).</p>
  
  <p>What can I do ? How can I restore my redis from the .rdb file?</p>
