differential Backup

[masumeh--]

we have a sql database server that have been scheduled to full backsup every day(12:00am) also i have scheduled differential backup every 3 hours.
i have a question, whether differntial backup is automatically taken from last full backup not first Full backup? so i can remove the differential Backups of yesterday???

Hi,

The differential backup is related to the last full backup.
