Restoring data

Restoring data: an overview

Restoring is the process of copying data from a backup and applying transaction logs to the data to roll it forward to the target recovery point. A backup contains sufficient transaction log records to allow rolling forward the active transactions as part of restoring each backup. Each backup also contains sufficient transaction logs to roll back any uncommitted transactions to bring the database to a consistent, usable state. The process of rolling forward uncommitted transactions, if any, and bringing the database online is known as Recovery.
Each SQL Server® restore scenario is implemented using one or more restore operations, which is called a restore sequence. A restore sequence moves data through one or more phases of restore. The possible phases of a restore include the data copy, redo (roll forward), and undo (roll back) phases, which are detailed in the following sections.
Redo is the process of reapplying logged changes to the data in the roll forward set to bring the data forward in time. To accomplish the redo, the SQL Server® Database Engine processes Transaction Log backups as they are restored. The engine starts with the log contained in the data copy backups listed in the preceding section and any Incremental Transaction Log backups that are then restored. Roll forward stops at the recovery point; this point is either the end of the log or a point specified in the SQL Server restore options for Incremental Transaction Log backups. Plug‑in for SQL Server supports both time-based and marked transaction-based PIT recovery.
