To avoid permanent data loss your company has to implement a file backup and recovery policy. File backup refers to copying and archiving files for the sole purpose of being able to restore them should data loss occur. If you back up your files, you can do a restore and go back to any backup prior to the data loss event. It is a good idea to back up files weekly or even daily as you never know when your system might crash. Recovery may also be necessary if you need to retrieve data after it was formatted, lost, corrupted or accidentally deleted. If you do not regularly back up databases or financial and customer data, you run the risk of losing them forever. There is no need to back up system files because they will be reinstalled when you do a system recovery. You don’t need to copy programs or applications either as they can be downloaded again should the need arise.

If you do a full backup all the data on your device will be backed up.

If you do an incremental backup you will only back up the files that are new or have changed since the previous backup. Restoring data from an incremental backup is time-consuming because sometimes you have to restore backup sessions dating back to the first one in order to restore a certain file.

A differential backup creates copies of all the files that have changed since the last full backup.
