All about Backup

Full Backup Method

A full backup usually includes your entire system and all its files. It's a basic backup method and all other metods are based on full backup. In each full backup session all data is copied. For example: all data base, file system, catalog on HDD.
It would be ideal to make full backups all the time, because they are the most comprehensive and are self-contained. However, the amount of time it takes to run full backups often prevents us from using this backup type. Full backups are often restricted to a weekly or monthly schedule, although the increasing speed and capacity of backup media is making overnight full backups a more realistic proposition.

Full backups, if you have the time to perform them, offer the best solution in data protection. In effect, a single backup can provide the ability to completely restore all backed-up files.However, you should be aware of a significant security issue. Each full backup contains an entire copy of the data. If the backup media were to be illegally accessed or stolen, the hacker or thief would then have access to an entire copy of your data.

Advantages: restore is the fastest.
Disadvantages: backing up is the slowest, the storage space requirements are the highest (compared to incremental backups or differential backups).
