Hi Friend
Full backup
Full backup is the starting point for all other backups and
contains all the data in the folders and files that are selected to be
backed up. Because the full backup stores all files and folders,
frequent full backups result in faster and simpler restore operations.
Remember that when you choose other backup types, restore jobs may take
longer.
Advantages of full backups
A full backup is often considered the most secure, reliable method of copying data. A few additional advantages include:
Restore and recovery times are shorter because complete data is always readily available.
All data is backed up at once, making version control easy to manage.
Backup files are easier to locate as they are all kept on the same storage medium.
Disadvantages of full backups
However, there is a trade-off with full backups and some disadvantages to the strategy are:
Higher bandwidth and more storage space is required.
Can be time-consuming to perform depending on the amount of data being backed up.
Backups can become redundant as unaltered files continue to be copied repeatedly.
If the copy of the data is leaked or compromised, the entire backup repository can be stolen.
Example of a full backup
In order to perform a full backup, the admin in charge of overseeing
the process must designate which files need to be copied and enforce a
backup schedule. For example, the admin might determine that a specific
hard disk needs to execute a full backup twice a week, on Tuesdays and
Fridays. On Tuesday, the entire directory of folders and files on that
drive will be copied. On Friday, any new files added to that drive will
be copied and all the existing directory from before will be copied
again.
I hope I've helped
