Backup–Transfer–FTP!

Having
a standby server in a remote site, copying backup files directly to a Disaster
recovery site or other requirements such as transfering files from one location
to another using FTP creates the need for creating a FTP batch file using a
changing parameter file. In this article, I will walk you through the whole process
of FTP by creating and using a dynamic FTP parameter file.

Windows FTP.exe
requires a file as a parameter to automate the FTP process. Below, is a
typical FTP batch file.


ftp -s:c:tempFTP.txt ftp.myclient.com

This FTP batch file gets its parameters
from a file called FTP.txt. Below is atypical FTP
parameter file.


myuserid
mypassword
CD /u/trannet
binary
put c:tempuserdatabase.bak
quit

The FTP.txt
file is static. In order to make it dynamic with a new backup file name every
time, the following code is used.

Step1: Create batch file

Create a batch file
c:tempftp.bat with the below given statement on the SQL Server Box.


ftp -s:c:tempFTP.txt ftp.myclient.com

Step2: Create a procedure
which creates the dynamic parameter file.


Use master
go
Create procedure usp_savefile @userid varchar(200),@password varchar(200),
@changepath varchar(200), @ftptype varchar(20),@ftpfilename varchar(200),
@ftpparafile varchar(200), @ftpbatchfile varchar(200)
as
–Created by: MAK
–Created date:
–Last updated date:
declare @text1 varchar(500)
set @text1 = ‘echo ‘[email protected] +”>” [email protected]
exec master.dbo.xp_cmdshell @text1
set @text1 = ‘echo ‘[email protected] +”>>” [email protected]
exec master.dbo.xp_cmdshell @text1
set @text1 = ‘echo ‘[email protected] +”>>” [email protected]
exec master.dbo.xp_cmdshell @text1
set @text1 = ‘echo ‘[email protected] +”>>” [email protected]
exec master.dbo.xp_cmdshell @text1
set @text1 = ‘echo ‘[email protected] +”>>” [email protected]
exec master.dbo.xp_cmdshell @text1
set @text1 = ‘echo quit’+”>>”[email protected]
exec master.dbo.xp_cmdshell @text1
exec master.dbo.xp_cmdshell @ftpbatchfile

Step 3: Create the procedure
which runs the backup command, create the ftp parameter file and transfer the
file to the FTP location using FTP.bat


Use master
go
Create procedure USP_ftpbackup @dbname varchar(128),@path varchar(500),
@ftptext varchar(500), @backuptype @varchar(20) as

–Created by: MAK
–Created date:
–Last updated date:
declare @backupname varchar(500)
declare @x varchar(500)
declare @dateandtime varchar(12)
declare @date datetime
declare @backup varchar(200)
set @date =getdate()
set @dateandtime = convert(varchar(20),@date,112) +case when
datepart(hh,@date) <10 then ‘0’+convert(varchar(1),datepart(hh,@date)) else
convert(varchar(2),datepart(hh,@date))
end
+case when datepart(mi,@date) <10 then
‘0’+convert(varchar(1),datepart(mi,@date)) else
convert(varchar(2),datepart(mi,@date))
end
set @backup = “Backup “[email protected] +” ” + @dbname+ ” to disk = ‘”+
@[email protected]+”_”[email protected]+”.bak’ ”
exec ( @backup)
–print @backup
set @backupname =’put ‘[email protected][email protected][email protected]+’.bak’
–Remember to change the parameters according to your requirement
exec usp_savefile ‘myuserid’,’mypassword’,’CD /u/trannet’ ,’binary’,
@backupname,@ftptext,’c:tempftpbackup.bat’
