A full database restore involves restoring the entire database from a backup. This strategy is suitable when the entire database needs to be restored, data consistency is crucial, and minimal downtime is acceptable.
The pros of a full database restore include fast restoration time (usually minutes or hours) and ensures data consistency.
The cons of a full database restore include requiring significant storage space for backups and being resource-intensive during the restore process.
An incremental database restore involves restoring only the changes made since the last full backup. This strategy is suitable when only a small portion of the database needs to be restored, data consistency is not critical, and downtime needs to be minimized.
The pros of an incremental database restore include fast restoration time (usually minutes), reduced storage space requirements for backups, and less resource-intensive during the restore process.
The cons of an incremental database restore include requiring a previous full backup as a reference point and can be more complex to implement and manage.
A logical database restore involves restoring the database by recreating it from a backup of the database's transaction log. This strategy is suitable when the entire database needs to be restored, but data consistency is not critical, minimal downtime is acceptable, and storage space for backups is limited.
