A server has 500GB of data that must be backed up nightly. The administrator has upgraded the old LTO2 drive to an LTO3, but the data still will not fit on a single tape. Which of the following…

The correct answer is A. Enable compression on the new drive D. Purchase LTO3 tapes for use in the new drive. Enabling compression on the LTO3 drive and using the correct LTO3 tapes together allow 500GB of data to fit on a single tape where it otherwise would not.

Question

A server has 500GB of data that must be backed up nightly. The administrator has upgraded the old LTO2 drive to an LTO3, but the data still will not fit on a single tape. Which of the following additional steps should the administrator perform to accommodate the data? (Select TWO).

Options

  • AEnable compression on the new drive
  • BReformat all tapes
  • CDelete unnecessary system files
  • DPurchase LTO3 tapes for use in the new drive
  • EPurchase new backup software

Why each option

Enabling compression on the LTO3 drive and using the correct LTO3 tapes together allow 500GB of data to fit on a single tape where it otherwise would not.

AEnable compression on the new driveCorrect

LTO3 supports hardware compression at roughly a 2:1 ratio, raising effective capacity from 400GB native to approximately 800GB, which is sufficient to hold 500GB of data on one tape.

BReformat all tapes

Reformatting tapes changes the tape structure but does not increase the physical capacity of LTO3 media.

CDelete unnecessary system files

Deleting system files is a data management action, not a backup configuration step, and does not address backup hardware or media capacity.

DPurchase LTO3 tapes for use in the new driveCorrect

LTO3 tapes are specifically required for reliable, rated operation in an LTO3 drive; using incompatible or older-generation tapes would prevent the drive from operating at its full native capacity.

EPurchase new backup software

New backup software cannot increase the physical storage capacity of the tape media or the drive.
