Along with the RDBMS software, Oracle provides two utilities that you can use to back up and restore the database. These utilities are Export and Import.

The Export utility dumps the definitions and data for the specified part of the database to an operating system binary file. The Import utility reads the file produced by an export, recreates the definitions of objects, and inserts the data

If Export and Import are used as a means of backing up and recovering the database, all the changes made to the database cannot be recovered since the export was performed. The best you can do is recover the database to the time when the export was last performed.

The Backup utility is located in the C:\Windows\Start Menu\Programs\ Tools directory.

For restoring the master db we have to stop the SQL Server first and then from command line we can type SQLSERVER -m which will basically bring it into the maintenance mode after which we can restore the master db.

On some system boards, resetting the contents of the CMOS can be accomplished by shorting a special pair of jumpers on the board. With other systems, you will need to remove or short across the backup battery to reset the CMOS information. In ATX systems, it will also be necessary to unplug the power from the commercial outlet to reduce the voltage to the CMOS registers. When the contents of the CMOS are reset, you must manually restore any non-default CMOS settings being used by the system.

Typing SYS C: at the DOS prompt will copy the IO.SYS, MSDOS.SYS, and COMMAND.COM system files from the boot disk to the hard disk drive.

If the clean boot disk has a copy of the FDISK program on it, you might attempt to restore the drive's master boot record (including its partition information) by typing the command FDISK /MBR.

Use TFTPdnld command at the rommon mode after that follow the instructions of the said command.
You must have a copy of the IOS in a TFTP Server to support this.

Traditional breeding techniques involve mixing thousands of genes, which in addition to providing the beneficial trait, also result in the loss of other traits of that crop considered to be valuable.
Significant time and effort is required to restore the other valued traits of that crop while maintaining the
desired trait using traditional breeding techniques.
Genetic modification permits food developers to add or enhance useful traits more specifically or remove
undesirable traits.
The technology permits food developers to add a desired trait in a more precise manner than traditional breeding without the loss of other beneficial characteristics since unwanted genes are not transferred.
