" " Process while

Select one of the following radio buttons to specify whether the backup operation is to be done online or offline.

Offline
The backup operation occurs offline (that is, no other application or user can be connected to the database or database partition when the backup is in progress). This is the default.

For information about forcing users off the database, see .
Note: For partitioned database environments only. In a partitioned database environment, if you are performing an offline backup of the catalog node, there can be no activity on the entire database.

Online
The backup operation occurs online (that is, other applications and users can be connected to the database or database partition when the backup is in progress).
Note:You can only take an online backup if the database or the database partition is enabled for forward recovery; that is, either the logretain or the userexit database configuration parameter (or both) is set on,, and a full offline backup of the database or the database partition has already been taken.

" " Performance

Use the following fields to specify the number and size of the buffers to be used for the backup operation. You can increase the number of buffers or the size of each buffer (or both) to cause the backup operation to complete faster. Note that increasing the value specified for either option causes the backup operation to use more memory.

Number of buffers
Type the number of buffers that are used for the backup operation. The default is 2. The valid range is from 1 to 65535.

Size of each buffer in 4KB pages
Type the size of each buffer in 4 KB pages. The current value is specified in the database configuration file. The default is 1024, and the range is from 16 to 524288.
