täysvarmuuskopiointi

Täysvarmuuskopiointi, known in English as full backup, is a method of data backup where an entire set of data is copied. This means every file, folder, and application is duplicated, regardless of whether it has changed since the last backup. The primary advantage of a full backup is that it provides the simplest and most straightforward method for restoring data. To recover information, only the most recent full backup needs to be accessed. This makes the restoration process faster and less prone to errors compared to other backup strategies that rely on combining multiple backup types. However, full backups also have drawbacks. They consume the most storage space because all data is copied each time, and they can take the longest to complete due to the sheer volume of data being transferred. This also translates to higher bandwidth usage, which can be a concern in some network environments. Despite the storage and time requirements, full backups are often used as a foundational element in a comprehensive backup strategy, with incremental or differential backups performed afterward to save space and time. They are crucial for ensuring complete data redundancy and are a cornerstone of disaster recovery planning for many organizations and individuals.
