So although the practice of doing daily fulls is unrealistic for most companies, at some point a full backup is required to support other backup procedures. Regardless of the daily backup method employed, at some point a baseline full backup is necessary to ensure that all data is duplicated. Relying on daily full backups is not a practical approach, but less frequent full backups provide the core data for a number of other, less time consuming backup methodologies.įor example, a weekly full backup coupled with incremental or differential daily backups is practical for most companies - even if the amount of data that must be protected is voluminous. ![]() Rather than being the essential and sole process of a daily data protection scheme, full backups have evolved into one of multiple key factors for effective data protection strategies. Types of backupsĪ full backup is one of four popular backup methods. Most backup software will maintain a catalog that indicates what was backed up when, to where and whether the process completed successfully. Those bits and bytes might well be needed for disaster recovery, but other techniques, such as disk mirroring or disk cloning are used to copy those key elements.ĭata backup software controls the full backup process and enables specialists managing the process to designate which volumes and files should be copied and the backup destination, or the specific media that the data will be copied to. Generally, applications, operating systems and other software aren't copied during a full backup. Typically, the data that is copied comprises files used by applications, some metadata that helps make the files more useful to the applications, logs and tracking files that document what the applications are processing as well as other control and management files. ![]() The files that are duplicated during the full backup process are designated beforehand by a backup administrator or other data protection specialist. A full backup is the process of making at least one additional copy of all data files that an organization wishes to protect in a single backup operation.
