I want to create a job of differential backup with 30 days data auto delete

[arun_akki]

Hi i want to create a job with differential backup, in which i will take a diffential backup after a full backup.
I want only 30 days backup not more that 30 days, after 30 days the old data of more than 30 days should be removed itself.

I AM USING BACKUP EXEC 2012.

So you need 30 copies of differential backup job and 1 full backup at the end of the month?

Ideally Most of the admin prefer Full backup over the weekend and incremental or diffrential backups during weekdays.

...the only way to accomplish this is to ensure that your Append/OPP settings are correct to allow for 30 days of DIFF backups to be kept.
