Question

suppose you make a full backup the first sunday of each month, a differential backup on each of the other sundays, and an incremental backup every tuesday and thursday. today is the 12th, which is the second wednesday of this month. which files (using the latest version available for each) would need to be combined to create a current synthetic full backup?

Answer 1

To create a current synthetic full backup, you would need to combine the latest version of the full backup made on the first Sunday of the month, the latest version of the differential backup made on the previous Sunday, and the latest versions of the incremental backups made on the previous Tuesday and Thursday.

Step-by-step explanation:

To create a current synthetic full backup, you would need to combine the latest version of the full backup made on the first Sunday of the month, the latest version of the differential backup made on the previous Sunday, and the latest versions of the incremental backups made on the previous Tuesday and Thursday.

Since today is the second Wednesday of the month, the most recent full backup would be from the previous month's first Sunday. The most recent differential backup would be from the previous month's second Sunday. The latest version of the incremental backups would be from the previous week's Tuesday and Thursday.

By combining the latest versions of these backups, you would have a current synthetic full backup.
