Question
An administrator is required to backup 250GB nightly utilizing a single LTO2 tape. The administrator reports that the tape drive is running out of available space before the job completes. Which of the following would allow the administrator to backup this data? (Select TWO).
Options
- AEnable compression on the LTO2 drive
- BUtilize LTO3 tapes in the existing drive
- CReduce the amount of data on the backup
- DReplace the LTO2 with LTO3 drive and tapes
- EDivide the data and back up half one night and half the next

Why each option
To back up 250GB nightly with an LTO2 drive, the administrator can either increase the effective capacity through compression or upgrade the hardware to a newer generation.
Enabling hardware compression on the LTO2 drive will increase its effective storage capacity, potentially allowing the 250GB of data to fit onto a single tape if the data is compressible.
LTO drives are backward compatible for reading, but an LTO2 drive cannot write to or utilize LTO3 tapes due to format and technology differences.
Reducing the amount of data on the backup does not meet the requirement to back up the specified 250GB nightly, as it alters the scope of the backup.
Replacing the LTO2 drive with an LTO3 drive and using LTO3 tapes would provide a significantly higher native capacity (400GB native for LTO3 vs 200GB for LTO2) and improved compression, easily accommodating the 250GB backup.
Dividing the data over multiple nights means the entire 250GB is not backed up nightly, which goes against the administrator's stated requirement for nightly backup of all 250GB.
