Final answer:
The backup method using a rotating schedule of backup media is the Grandfather, Father, Son method, which includes monthly, weekly, and daily backups.
Step-by-step explanation:
The backup method that uses a rotating schedule of backup media to ensure long-term information storage is known as the Grandfather, Father, Son method. This strategy involves creating three levels of backup copies: the Grandfather (monthly backup), the Father (weekly backup), and the Son (daily backup). By cycling through these backups on a regular, rotating basis, organizations are able to maintain a series of recovery points that provide significant historical data depth, while also mitigating the risk of data loss. Full archival, backup server, and differential backup are different methods or concepts in the realm of data backup and recovery, but they do not involve a rotating schedule like the Grandfather, Father, Son method does.
The backup method that uses a rotating schedule of backup media to ensure long-term information storage is A. Grandfather, Father, Son. This method involves using three sets of backup media: the 'father' set for the current backup, the 'son' set for the previous backup, and the 'grandfather' set for backups from even earlier times. This rotation ensures that there are multiple copies of the data stored over time, providing a robust and reliable backup strategy.
