A SAN attached production file server is required to be backed up nightly according to company policy.
Recently the data to be backed up has increased to approximately 4TB.
Currently, the server has a single attached LTO2 tape drive.
Which of the following should the server administrator do to provide enough backup capacity for the nightly job?
Click on the arrows to vote for the correct answer
A. B. C. D.D.
Option A - Replacing the backup software with a more efficient application may help in reducing the time taken for the backup job but it will not increase the capacity of the backup medium. Therefore, this option can be eliminated.
Option B - Reducing the amount of data to be backed up is not a feasible option as the company policy requires the entire data to be backed up. Therefore, this option can be eliminated.
Option C - Replacing the LTO2 tape drive with an LTO3 tape drive will increase the capacity of the tape drive from 200GB to 400GB per cartridge. This will provide more capacity to store data and allow for the backup of larger amounts of data. This option is a viable solution and can be considered.
Option D - A tape library consists of multiple tape drives and can store multiple tapes, which increases the backup capacity significantly. This option is the best solution as it not only provides more backup capacity but also offers the added advantage of automation and allows for multiple backups to be performed simultaneously. However, it may require additional investment as compared to other options.
Therefore, the correct answer to this question would be Option D - Replace the single tape drive with a tape library.
