These are the 4 Types of Data Backup and Recovery:
A full backup is when all the data in a system is backed up. It is the most comprehensive nad basic of all backup types. The advantage of a full backup is that the process of restoring lost data is much faster. The disadvantage of a full backup is that it takes longer to execute and requires more space than other types of backups.
An incremental backup only backs up the changes that were made since the previous backup. With this type of backup, the process of restoring lost data takes more time but the backup process is faster, allowing backups to be carried out more often if needed.
Similar to an Incremental backup, each time it is run, a differential backup only saves the data that has changed since the last full backup. A differential backup is different in that it provides a way of backing up changed data to the same convenient location as all new data. This allows for faster restore time but also takes up more time and storage space than an Incremental backup.
A mirror backup means that an exact copy of your source data is made and backed up. The advantage of this type of backup is that you are much less likely to be storing old obsolete files. When you delet files, they are also deleted from the mirror backup every time your system backs up. The disadvantage of a mirror backup is that if a file is accidentally deleted it can be permanently lost if the accidental deletion isnt discovered before your next scheduled backup.
