Which L3W characteristic improves backup efficiency?

Incremental backups significantly enhance backup efficiency by only capturing the changes made since the last backup was performed. This method conserves storage space and reduces the time required for backup operations, as it eliminates the need to back up unchanged data repeatedly. It focuses solely on the modified files or data segments, which leads to faster completion times for backup processes and more efficient use of network and storage resources.

In contrast, relying solely on full backups would not improve efficiency, as they require a comprehensive copy of all data every time, regardless of whether it has changed. Conducting backups manually tends to increase the risk of human error and may lead to inconsistent backup schedules. Monthly data reviews, while they can contribute to data management practices, do not have a direct impact on the efficiency of the backup process itself. Incremental backups, therefore, represent a more advanced and efficient approach to data protection within L3W practices.
