Backup einer SQL-Express-DB mittels Batchdatei

[DrMueller]

Hallo,
ich hoffe ich bin mit meiner Frage hier richtig.
Ich soll mit einer Batchdatei ein Backup einer SQL-Express-DB erstellen.
Ich habe schon diverse Foren etc durchsucht, aber nichts gefunden.
Ist dies überhaupt möglich, wenn ja, hat mir wer nen Tipp?
Ich danke im Vorraus.

Hallo Dr. Müller,

also hier ein Auszug aus dem T-SQL-Handbuch um per SQL-Befehl ein Backup zu erstellen, und um so einen Befehl auszuführen, können Sie osql (mal danach googlen, wenn unbekannt) nutzen... (Hab das ganze zwar noch nicht ausprobiert, sollte aber funktionieren ):

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 ] ]
]

Sichern bestimmter Dateien oder Dateigruppen:

BACKUP DATABASE { database_name | @database_name_var }
< file_or_filegroup > [ ,...n ]
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 } ]
[ [ , ] { NOSKIP | SKIP } ]
[ [ , ] { NOREWIND | REWIND } ]
[ [ , ] { NOUNLOAD | UNLOAD } ]
[ [ , ] RESTART ]
[ [ , ] STATS [ = percentage ] ]
]

Sichern eines Transaktionsprotokolls:

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 }
}

Kürzen des Transaktionsprotokolls:

BACKUP LOG { database_name | @database_name_var }
{
[WITH
{ NO_LOG | TRUNCATE_ONLY } ]
}
