Setting data transfer and/or transaction log backup options


This step offers some additional options that may be useful for setting up database backup operation: data transfer options and/or transaction log backup options.

 

Data transfer options

(only displayed for SQL Server 2008 and higher)

 

Backup Database - Setting data transfer options

 

 

Buffer count

Specifies the total number of I/O buffers to be used for the backup operation.

 

Max transfer size

Specifies the largest unit of transfer in bytes to be used between SQL Server and the backup media.

 

Note: If 0 is specified (by default), the default values will be used.

 

 

Transaction log backup options

(only displayed if the RadioButton Transaction log is selected at the Setting backup type and options step).

 

RadioButton Truncate inactive log items

The log is truncated after all the records within one or more virtual log files become inactive.

 

RadioButton No truncate inactive log items

Specifies that the log not be truncated and causes the Database Engine to attempt the backup regardless of the state of the database. This option allows backing up the log in situations where the database is damaged.

 

RadioButton No recovery (leaves database in restoring state)

Backs up the tail of the log and leaves the database in the RESTORING state. This is useful when failing over to a secondary database or when saving the tail of the log before a restore operation.

 

RadioButton Standby (leaves database in read-only and standby mode)

Backs up the tail of the log and leaves the database in a read-only and STANDBY state. Using standby mode requires a standby file, specified by Undo file name.
