   A financial services company has a backup strategy that performs a full backup every Sunday and incremental backups every night. The company's compliance team requires that backups be retained for 7 years, and the IT team must be able to restore data from any point in the last 30 days within 2 hours. The current restore process requires loading the full backup and then applying all incrementals, which can take up to 5 hours for a 30-day-old restore point. Which change would most effectively reduce restore time while still meeting the retention requirement?

   • ASwitch to differential backups on a daily basis and keep the weekly full backup.
   • BKeep the incremental backups but store them on faster SSD storage.
   • CPerform a full backup every night instead of weekly.
   • DReduce the retention period to 1 year to lower the number of backups.

   A university research lab stores years of experimental data on a network drive. The lab's grant requires that data be retained for five years after the project ends. The lab currently has no backup system. A researcher accidentally deletes a folder containing six months of data. What is the most important reason the lab should implement a backup strategy now?

   • ATo reduce the storage space used on the network drive.
   • BTo make the network drive faster for researchers.
   • CTo ensure data can be recovered after accidental deletion or corruption.
   • DTo automatically delete old data after five years.

   A hospital's radiology department generates large imaging files (MRI, CT scans) that are stored on a SAN. The department needs to retain images for 7 years for legal reasons, but the images are rarely accessed after the patient's treatment ends. The hospital's backup window is limited to 4 hours each night. The current full backup of the SAN takes 6 hours and is causing performance issues. Which strategy best addresses the backup window and long-term retention?

   • APerform a full backup every other night and accept the longer window.
   • BUse incremental backups during the week and a full backup on weekends when the window is longer.
   • CReduce the retention period to 3 years to cut backup size.
   • DStore all images on tape immediately and delete them from the SAN.

   • BStore all backups on high-speed external SSDs for the full seven years.
   • CPerform only incremental backups and store them in the cloud.
   • DUse tape backups for the seven-year archive and keep a short-term on-site copy for quick access.
