Tenant Data Recovery (TDR) is a process of ordered steps enabling database administrators to recover accidentally deleted table data and multi-tenant sequences for a tenant or group in a multi-tenant database without taking the entire database offline.

Once the need to restore data or a sequence is discovered, the high-level restoration process is as follows:

1. Locally restore your most recent backup of your production database to a temporary location.
2. Roll forward the after-image files of your production database to your temporary database if your production database is enabled for after-imaging.
3. Move data from the temporary database to your production database.
4. Clean up.

Figure 1 illustrates the flow of the TDR process. The details of each step are discussed in the sections that follow.
