There are many reasons why your computer may suddenly lose its data, including some of the following: hardware fails, virus, incorrect keystrokes (UPDATE, DELETE), software bug, disaster (fire or flood). You’ll want to have a strategy for recovering database data if you are concerned that you might lose your data one day. One thing you can do, that’s easy to make happen, is a full database backup.
For a full database backup, you would back up your data once a day, say, or after you turn your computer’s apps off at night. You can easily restore your computer data’s to the time when the last backup occurred, if you need to. Many formats and applications do this automatically. A full database backup is an excellent idea, and it backs up all information needed to restore your computer, including Meta information. If you need to restore your computer, it will go back to the time of the last backup.
Differential backups are something new. If you need to restore your computer before you back up your data, you are at a loss, and you lose a whole day’s work if you are backing up your computer at night alone. You can also perform database backups more frequently, if you need to. One option, the differential backup, allows you to restore the last full backup and then use just the differential backup you last performed.

Manual database backup
You can perform a differential backup by typing in, for example:
BACKUP DATABASE [name of database]
TO DISK= ‘[path of database]’
WITH INIT, DIFFERENTIAL;
If you’re interested in a transaction log backup, that is an option also. This gives you a backup of every single event that has posted in a database, and it is possible to recover your database to any state you need to. You can actually recover the database to any point in time that you want to. And even if the files are destroyed, you can still perform a backup to any point in time you need to.
One option is to use both transaction and differential backups. This is a smart way to recover your data. You can first restore to the last full backup, then the last differential backup, then all the other transaction log backups that have occurred since then. These are just some ways, but if you are keen on making sure to save your data, you’ll want to consider what works best for you.
