Hi - I currently use a job to backup my db (MSDE 2000) to the same drive the database is on (this is a dedicated server I lease - with no tape backup - and I run my web applications and MSDE 2000 together on it).
So my DB gets backed up each night, with the datestamp as a filename identifier. The Job then sends an email to me using the XP_CDO dll to let me know if it was successful, or if it failed. This all works well.
However, is it possible from within my job, to invoke winzip, and zip the newly created backup file, and attach it to my email which is sent from the job?
I just want to be able to have a sort of off-site backup, just in case.
Thanks for any help,
Mark

Yep. You could do it from the command shell if you wanted to.
declare @cmd varchar(255)
set @cmd = 'C:\temp\pkzip.exe whatever.zip *.*'
EXEC master..xp_cmdshell @cmd, no_output

Hi - thank you.
I'm not familiar with this - are theer examples which demonstrate hjow to implement anywhere?
Thanks, Mark

because of email size constraints, i would suggest having the job FTp the file to another location instead.
many email servers have a 4 meg or 10 meg limit on them, which might doink your email plans in the future as your db or log grows.
there is a script named "FTP files using SQL stored procedure" here on SCC:

I use this procedure to perform backups and zip the backup files. I use winzip 9 with the command line interface installed. This procedure only uses a few of the options that winzip will give you but it can get you started.
create procedure usp_backup_and_zip
@dbName sysname = null
,@BackupLocation varchar(500) = null
,@ZipProgram varchar(500) = null
,@RemoveBackup tinyint = null
,@Encrypt tinyint = null
,@Password varchar(50) = null

-- this procedure will accept the database name to be
-- backed up. It will
-- backup the selected database and zip it. Optionally it will encrypt the backup file
-- as well using the encryption methods within WINZIP. The naming convention used will
-- be ... ServerName_dbName_ZIP_ccyymmddhhmmss.zip
-- Return Codes: 0 - success
-- 1 - failure
-- Accepts the following parameters:
-- @dbName - (required) This is the database to be backed up
-- @BackupLocation - (required) This will be both the location of the backup and
-- the resting place for the zip file
-- @ZipProgram - (optional) path and .exe for the zip program, will default to
-- C:\WINZIP\WZZIP if not otherwise supplied
-- @RemoveBackup - (optional) default to 0, if 1 then remove the backup file when done
-- @Encrypt - (optional) default to 0, this is the same as no encryption; if a password
-- is supplied this will default to 1.
-- 0 - no encryption
-- 1 - standard Zip 2.0 encryption (password required)
-- 2 - AES128 encryption (password required)
-- 3 - AES256 encryption (password required)
-- @Password - (optional) password for zip file NOTE: THIS MUST BE RETAINED IN A SAFE
-- PLACE, IF IT IS USED THERE IS NO WAY OF RECOVERING THE PASSWORD.
