SQL Job will be good choice to implement these scenarios. Now To track the 7 days older date there may be many approaches. One i am writing which i've seen in some applications. you can have a column with 'Created Date'/'Updated Date' and on creating/modifying just update this column.

As Peeyush Pachaori has suggested I would too use Sql Agent's Job for this task.
In order to delete records from tables you must keep track of insertion/update for every record, cascade deletion could be handy as well.

deletion code:

SQL

DELETE FROM MyTable
WHERE LastUpdateTime < @requiredDate

code for diff backup:

SQL

BACKUP DATABASE [DBName] TO  DISK = N'Backup_Path'
WITH  DIFFERENTIAL , NOFORMAT, NOINIT,
NAME = N'DBName-Differential Database Backup', SKIP, NOREWIND, NOUNLOAD,  STATS = 10
GO

I hope this helps.
