备份整个数据库：
BACKUP DATABASE { database_name | @database_name_var }
TO < backup_device > [ ,...n ]
[ WITH
[ BLOCKSIZE = { blocksize | @blocksize_variable } ]
[ [ , ] DESCRIPTION = { 'text ' | @text_variable } ]
[ [ , ] DIFFERENTIAL ]
[ [ , ] EXPIREDATE = { date | @date_var }
| RETAINDAYS = { days | @days_var } ]
[ [ , ] PASSWORD = { password | @password_variable } ]
[ [ , ] FORMAT | NOFORMAT ]
[ [ , ] { INIT | NOINIT } ]
[ [ , ] MEDIADESCRIPTION = { 'text ' | @text_variable } ]
[ [ , ] MEDIANAME = { media_name | @media_name_variable } ]
[ [ , ] MEDIAPASSWORD = { mediapassword | @mediapassword_variable } ]
[ [ , ] NAME = { backup_set_name | @backup_set_name_var } ]
[ [ , ] { NOSKIP | SKIP } ]
[ [ , ] { NOREWIND | REWIND } ]
[ [ , ] { NOUNLOAD | UNLOAD } ]
[ [ , ] RESTART ]
[ [ , ] STATS [ = percentage ] ]
]
备份特定的文件或文件组：
BACKUP DATABASE { database_name | @database_name_var }
< file_or_filegroup > [ ,...n ]
TO < backup_device > [ ,...n ]
[ WITH
[ BLOCKSIZE = { blocksize | @blocksize_variable } ]
[ [ , ] DESCRIPTION = { 'text ' | @text_variable } ]
[ [ , ] DIFFERENTIAL ]
[ [ , ] EXPIREDATE = { date | @date_var }
| RETAINDAYS = { days | @days_var } ]
[ [ , ] PASSWORD = { password | @password_variable } ]
[ [ , ] FORMAT | NOFORMAT ]
[ [ , ] { INIT | NOINIT } ]
[ [ , ] MEDIADESCRIPTION = { 'text ' | @text_variable } ]
[ [ , ] MEDIANAME = { media_name | @media_name_variable } ]
[ [ , ] MEDIAPASSWORD = { mediapassword | @mediapassword_variable } ]
[ [ , ] NAME = { backup_set_name | @backup_set_name_var } ]
[ [ , ] { NOSKIP | SKIP } ]
[ [ , ] { NOREWIND | REWIND } ]
[ [ , ] { NOUNLOAD | UNLOAD } ]
[ [ , ] RESTART ]
[ [ , ] STATS [ = percentage ] ]
]
备份一个事务日志：
BACKUP LOG { database_name | @database_name_var }
{
TO < backup_device > [ ,...n ]
[ WITH
[ BLOCKSIZE = { blocksize | @blocksize_variable } ]
[ [ , ] DESCRIPTION = { 'text ' | @text_variable } ]
[ [ ,] EXPIREDATE = { date | @date_var }
| RETAINDAYS = { days | @days_var } ]
[ [ , ] PASSWORD = { password | @password_variable } ]
[ [ , ] FORMAT | NOFORMAT ]
[ [ , ] { INIT | NOINIT } ]
[ [ , ] MEDIADESCRIPTION = { 'text ' | @text_variable } ]
[ [ , ] MEDIANAME = { media_name | @media_name_variable } ]
[ [ , ] MEDIAPASSWORD = { mediapassword | @mediapassword_variable } ]
[ [ , ] NAME = { backup_set_name | @backup_set_name_var } ]
[ [ , ] NO_TRUNCATE ]
[ [ , ] { NORECOVERY | STANDBY = undo_file_name } ]
[ [ , ] { NOREWIND | REWIND } ]
[ [ , ] { NOSKIP | SKIP } ]
[ [ , ] { NOUNLOAD | UNLOAD } ]
[ [ , ] RESTART ]
[ [ , ] STATS [ = percentage ] ]
]
}
< backup_device > ::=
{
{ logical_backup_device_name | @logical_backup_device_name_var }
|
{ DISK | TAPE } =
{ 'physical_backup_device_name ' | @physical_backup_device_name_var }
}
< file_or_filegroup > ::=
{
FILE = { logical_file_name | @logical_file_name_var }
|
FILEGROUP = { logical_filegroup_name | @logical_filegroup_name_var }
}
截断事务日志：
BACKUP LOG { database_name | @database_name_var }
{
[ WITH
{ NO_LOG | TRUNCATE_ONLY } ]
}
