What is a simple command line program or script to backup SQL server databases?

Question

I\'ve been too lax with performing DB backups on our internal servers.

Is there a simple command line program that I can use to backup certain databases in SQL Serv

Answer 1

Schedule the following to backup all Databases:

Use Master

Declare @ToExecute VarChar(8000)

Select @ToExecute = Coalesce(@ToExecute + 'Backup Database ' + [Name] + ' To Disk =     ''D:\Backups\Databases\' + [Name]   + '.bak'' With Format;' + char(13),'')
From
Master..Sysdatabases
Where
[Name] Not In ('tempdb')
and databasepropertyex ([Name],'Status') = 'online'

Execute(@ToExecute)

Answer 2

Eventual if you don't have a trusted connection as the –E switch declares

Use following command line

"[program dir]\[sql server version]\Tools\Binn\osql.exe" -Q "BACKUP DATABASE mydatabase TO DISK='C:\tmp\db.bak'" -S [server] –U [login id] -P [password]

Where

[program dir] is the directory where the osql.exe exists

On 32bit OS c:\Program Files\Microsoft SQL Server\

On 64bit OS c:\Program Files (x86)\Microsoft SQL Server\

[sql server version] your sql server version 110 or 100 or 90 or 80 begin with the largest number

[server] your servername or server ip

[login id] your ms-sql server user login name

[password] the required login password

Answer 3

You could use a VB Script I wrote exactly for this purpose: https://github.com/ezrarieben/mssql-backup-vbs/

Schedule a task in the "Task Scheduler" to execute the script as you like and it'll backup the entire DB to a BAK file and save it wherever you specify.

Answer 4

To backup a single database from the command line, use osql or sqlcmd.

"C:\Program Files\Microsoft SQL Server\90\Tools\Binn\osql.exe" 
    -E -Q "BACKUP DATABASE mydatabase TO DISK='C:\tmp\db.bak' WITH FORMAT"

You'll also want to read the documentation on BACKUP and RESTORE and general procedures.

Answer 5

If you can find the DB files... "cp DBFiles backup/"

Almost for sure not advisable in most cases, but it's simple as all getup.
