The database automatically backs up and deletes the backup files 30 days ago.

Drop procedure dbo. SP_BackUpPortal

2. Create a call ratio to process a file

Echo Backup database daily, if the day is Sunday do a full back up else do a Increment backup
SQLCMD. EXE-S Server/Instance-d DataBaseName-Q "exec dbo. SP_BackUpPortal"

Echo delte the backfile which generated before 30 days

FORFILES/p d:/BackUp/Portal/D-30/c "cmd/c del @ path"

If % date :~ 0, 3% = Sun goto BackByMossCmd
Exit
: BackByMossCmd
Echo Backup by the mosscmd
Cd C:/Program Files/Common Files/Microsoft Shared/web server extensions/12/BIN
C:
STSADM. EXE-o backup-url http: // mossSite/-filename D:/BackUp/Portal/MossCmdPortalBack % date :~ 10,4%-% date :~ 4,2%-% date :~ 7,2%. bak
Exit

3. Add the backup file script that was deleted 30 days ago to the batch processing.

FORFILES/p d:/BackUp/Portal/D-30/c "cmd/c del @ path"

4. Create a windows scheduled task

You don't have.
