Question 18/87
A backup administrator has defined a backup policy The policy requires full backups to be performed at 9 PM every Sunday and incremental backups performed at 9 PM the remaining days If files were accidentally deleted Thursday morning, how many backup copies are required to restore the files?
Correct Answer: A
The backup policy requires full backups to be performed every Sunday at 9 PM and incremental backups at 9 PM on the remaining days. If files are deleted on Thursday morning, the most recent full backup would be from Sunday, and the incremental backups would be from Monday, Tuesday, and Wednesday. To restore the files, you would need:
* The full backup from Sunday
* The incremental backup from Monday
* The incremental backup from Tuesday
* The incremental backup from Wednesday
So, three backup copies are required: the full backup and the incremental backups from the last three days.

* The full backup from Sunday
* The incremental backup from Monday
* The incremental backup from Tuesday
* The incremental backup from Wednesday
So, three backup copies are required: the full backup and the incremental backups from the last three days.
