Question

A company has recently upgraded all backup hardware and media from DLT IV to LTO3 tapes and tape drives. Several weeks after the upgrade, the development team discovers a corruption in one of the application servers and must restore from one of the DLT IV tapes. Which of the following steps are necessary for the server administrator to use these tapes?

Options

  • AReformat the DLT IV tape in LTO3 format. Load the tape.
  • BInstall the DLT IV driver on the LTO3 drive. Load the tape.
  • CLoad the DLT IV tape into the LTO3 drive.
  • DReplace the LTO3 drive with a DLT IV tape drive. Load the tape.

Why each option

To restore data from older DLT IV tapes after upgrading to LTO3 hardware, the administrator must replace the LTO3 drive with a DLT IV tape drive.

AReformat the DLT IV tape in LTO3 format. Load the tape.

Reformatting a DLT IV tape in LTO3 format is not possible on an LTO3 drive, as it cannot read DLT IV tapes, and doing so would erase the existing data.

BInstall the DLT IV driver on the LTO3 drive. Load the tape.

Installing a DLT IV driver on an LTO3 drive will not enable it to read DLT IV tapes, as drivers cannot overcome fundamental hardware incompatibility between different tape technologies.

CLoad the DLT IV tape into the LTO3 drive.

Loading a DLT IV tape into an LTO3 drive will not allow it to be read, as the two tape technologies are physically and fundamentally incompatible.

DReplace the LTO3 drive with a DLT IV tape drive. Load the tape.Correct

LTO3 tape drives are not backward compatible with DLT IV tapes because they represent distinct and incompatible tape technologies. Therefore, a DLT IV tape drive is necessary to read the older media.
