Backup a SQL Server database and transfer it to Dropbox.

Hi,

I want to backup a SQL Server database using a bat file.

This is the contents of the bat file when I backup it on my laptop :

cls
set SERVERNAME=DESKTOP-6PULTF9\SQLEXPRESS05
set DATABASENAME=AssetManagement
set DATABASESHOP=HuntsmanShop
set datestr=%date:~6,4%%date:~3,2%%date:~0,2%
set timestr=%Time:~0,2%%Time:~3,2%%Time:~6,2%
set FileName=%DATABASESHOP%_%DATABASENAME%_%datestr%%timestr%.bak
set BAK_PATH=C:\Data\Test\
set DEST_FILE=%BAK_PATH%%FileName%
:: --------------------------------------------------
:: BACKUP Database
:: NOTE: If error "access is denied" appear - go to service properties - log on.
sqlcmd -E -S %SERVERNAME% -d master -Q "BACKUP DATABASE [%DATABASENAME%] TO DISK = N'%DEST_FILE%' WITH INIT , NOUNLOAD , NAME = N'%DATABASENAME% backup', NOSKIP , STATS = 10, NOFORMAT"

and this works perfectly.

Now when I want to make a backup to a Dropbox folder it doesn't work :

cls
set SERVERNAME=DESKTOP-6PULTF9\SQLEXPRESS05
set DATABASENAME=AssetManagement
set DATABASESHOP=HuntsmanShop
set datestr=%date:~6,4%%date:~3,2%%date:~0,2%
set timestr=%Time:~0,2%%Time:~3,2%%Time:~6,2%
set FileName=%DATABASESHOP%_%DATABASENAME%_%datestr%%timestr%.bak
set BAK_PATH=C:\Users\miche\Dropbox\Huntsman Shop\Backup\
set DEST_FILE=%BAK_PATH%%FileName%
:: --------------------------------------------------
:: BACKUP Database
:: NOTE: If error "access is denied" appear - go to service properties - log on.
sqlcmd -E -S %SERVERNAME% -d master -Q "BACKUP DATABASE [%DATABASENAME%] TO DISK = N'%DEST_FILE%' WITH INIT , NOUNLOAD , NAME = N'%DATABASENAME% backup', NOSKIP , STATS = 10, NOFORMAT"

I have been looking for a solution for a long time but I can't find it.
What am I doing wrong?
Thanks in advance.
Regards
Michel
