Creating full backups can consume too many resources - including time, storage, and network bandwidth - to implement frequently. It’s essential to have all data entirely backed up, but this backup is best used periodically. Here is how the common types of backups compare: Full backupsįull backups represent complete copies of all configured data. Less common types include incremental-forever backups and synthetic backups. A complete restore from such a system would require restoring the latest full backup and the latest differential backup followed by any incremental backup since the latest differential backup.įull backups, differential backups, and incremental backups are all fairly typical enterprise cloud backup methods. For example, a company might perform a monthly full backup, followed by weekly differential backups and daily incremental backups. Differential backups may be combined with incremental backups. A complete restore from such a system requires restoring the full backup followed by restoring the data found in each incremental backup.Ī related concept is a differential backup that backs up any data that has changed since the last full backup rather than the last incremental backup. No new information is lost if full and incremental backup methods are correctly combined over time. A full backup covers all folders and files throughout a system. If an incremental backup is taken before a full backup is performed, the backup system forces a full backup instead. Users often compare the full backup to the incremental backup to contrast the typical method as an alternative.Īn incremental backup process compares current data against a prior full backup. An incremental backup is a basic technique for securely archiving data and files.
