Can anybody help in this matter

Original database size 100 MB
Backup files created, in scheduled time but size was 357 MB.

While creating task for data backup,
backup type full, backup will expire options was 0 days, I configured the schedule as recurring (enabled checked),occurs daily, occurs one daily and fixed the time for daily routine.

How I can reduce the size of .bak files in a manageable size.

What is the size of database files (.MDF, .NDF) and transaction log files (.LDF)?

Do you take transaction log backups regularly?

.mdf = 80 Mb
.ldf =26 Mb approximately.

It was configured in backup job with the option full database backup.

Whereas .bak file producing 350MB. Did I configured wrong? If I did then what should be the right option.

* Another question : If I delete the last backup file .bak and assign new plan with management wizard, any problem with that.

How are you performing the backups?

Maintenance plan? Script in a job? Manual running of a script?

Right clicking in the database selecting task then backup, assigning job by selecting script action to job generated by sql server and schedule. Not maintenance plan or writing any script personally. I am steel learning. But may be database backups are growing because service is adding the new backup with the old backups not replacing older one. I have selected expired on 0 (zero) days.

deos your script has constant file name like the name of your 300+ mb file and it has

"WITH NOFORMAT, NOINIT" option?

then it is updating the backup on same file.

backup will expire options was 0 days


This option is equivalent to infinite days (never expire)

Run following sql to check how many backups your media file has?

RESTORE HEADERONLY FROM DISK = 'BackupFile.bak'

I think you configured backup with append option. So just configured new backup with default options.
