The point to which the database can be recovered depends on the backup acquisition mode that was specified during backup acquisition (specification of the -M option of the pdcopy command). The following table shows the points to which the database can be recovered, depending on the backup acquisition mode.

Table 21-1 Points to which the database can be recovered depending on the backup acquisition mode

Backup acquisition mode (-M option specification)	Backup acquisition point	Most recent synchronization point	Recovery with range specification
Referencing/updating-impossible mode (-M x option specification)	R	R	R
Referencing-permitted mode (-M r option specification)	R	R	R
Updatable mode (-M s option specification)#	--	R	R

R: Database can be recovered to this point.

--: Database cannot be recovered to this point.

#: If the backup was made with the updatable mode specified, database recovery will require what was the system log current file at the time the backup was made. The corresponding unload log file will be needed as input to the pdrstr command.

The name and generation number of the system log file that will be required for database recovery will be output in the pdcopy command's processing results output file.
