The administrator is trying to backup 250GB of data nightly using a single LTO2 tape but the job is not completing because the tape drive runs out of available space before the backup completes. To solve this problem, the administrator can take the following steps:
Enable compression on the LTO2 drive: LTO2 tape drives have built-in hardware compression, which can significantly increase the amount of data that can be stored on a single tape. By enabling compression, the administrator can potentially double the amount of data that can be backed up on a single tape, allowing the entire backup to complete within the available space.
Utilize LTO3 tapes in the existing drive: LTO3 tapes have a higher capacity than LTO2 tapes, which can help to accommodate the larger amount of data that needs to be backed up. While LTO3 tapes may not fit perfectly in an LTO2 drive, they are typically backward compatible and can still be used to store data at the LTO2 capacity.
Reduce the amount of data on the backup: The administrator may need to prioritize which data is being backed up and eliminate any unnecessary or redundant files, in order to fit within the available space on a single tape.
Replace the LTO2 with LTO3 drive and tapes: While this would require additional investment, upgrading to an LTO3 drive and tapes would provide a larger capacity and faster transfer speeds, allowing the entire backup to be completed within a single tape.
Divide the data and back up half one night and half the next: The administrator can divide the data into two parts and backup one half of the data on one night, and the other half on the next night. This would require a manual process of dividing and scheduling the backup, and may not be a desirable solution for systems that require continuous uptime.
Therefore, options A (Enable compression on the LTO2 drive) and B (Utilize LTO3 tapes in the existing drive) are the two most effective solutions for the administrator to backup 250GB nightly using a single LTO2 tape.
