Differential and Full Backups

[Shyam]

PLEASE HELP...

WE ARE DOWNLOADING THE BACKUP FILE FROM OTHER BRANCH OFFICE AND THE FILE SIZE IS GROWING LIKE HELL SO I AM CHANGING THE BACKUP POLICY TO DOWNLOAD THE DIFFERENTIAL BACKUP FILES EVERYDAY. BUT EVEN THE FILE SIZE GROWS DAY BY DAY UNTILL WE TAKE THE FULL BACKUP THERE. SO I WANT TO TAKE A DIIFERNETIAL BACKUP AND THEN IMMIDIATELY A FULL BACKUP AT THE REMOTE SERVER END. SO MY NEXT DIFFERNTIAL BACKUP WILL HAVE THE DATA OF ONLY PREVIOUS DAY.
FOR THIS I AM SCHEDULING A JOB WHICH FIRST TAKES A DIFFERENTIAL BACKUP AND THEN IMMIDIATELY FULL BACKUP EVERYDAY AT 12.00AM.
BUT I HAVE A CONCERN.. WHILE TAKING THE DIFFERENTIAL BACKUP ANY TRANSACTIONS THAT ARE TO BE COMMITED WILL NOT COMMIT UNTIL THE DIFFERENTIAL BACKUP COMPLETES. BUT IMMIDIATELY I AM STARTING FULL BACKUP. IS THERE ANY CHANCE THAT A TRANSACTION GETTING COMMITTED IN BETWEEN THESE TWO STEPS. IF SO IS THERE ANY WAY .. NOT RELEASE THE DATABASE UNTILL THESE 2 BACKUPS ARE COMPLETED?? I AM RUNNING IT AS A JOB..
ANY SUGGESTION??

THANKS IN ADVANCE.. :-)
