Hello CrazyJoe,
yes. Go to /Steam/steamapps/common/Eco/Eco_Data/Server/Storage/Backups and move the content of the last working backup to the storage folder. (.db and .eco file)

Please note that Eco uses database technology and that doesn't cope well with any ungraceful exits, so those will lead to savegame corruption. Best to prevent that in the first place.
