Backup MSSQL Database To External Path

It is very popular question from my clients. They have web access only to MS SQL database, but have to backup it to the external path. Ok, it can be done easy:

1. At the external server/computer make a folder, for example "C:\External_Backup".
2. Then go to the properties of this folder, tab "Sharing". Make public share with name "External_Backup" and add permissions for "Everyone" and "ANONYMOUS LOGON". Do not worry - its for few mins only, then we disable it.
3. Temporary disable Firewall.
4. Try to connect to this share from the Explore in this way "\\your_ip\External_Backup". You can see files and peform any actions in this folder.
5. In the web client of MSSQL database run query like this: BACKUP DATABASE your_db_name TO DISK = '\\your_ip\External_Backup\your_db_name.bak';
6. Enable Firewall and remove share from the public access.
