示例sql脚本以压缩和传输数据库备份文件

Question

I was looking for a sample sql script to zip my database backup file (.bak) and transfer to a remote location. Please share if you have it with you.

Answer 1

You can use xp_cmdshell to invoke the commands for zipping and copying. In the sample here, I am using winzip command line (for zipping/unzipping) and xcopy for transferring files.

EXEC master..xp_cmdshell 'C:\"Program Files"\WinZip\wzzip C:\Database.bak.zip C:\Database.bak';
EXEC master..xp_cmdshell 'C:\"Program Files"\WinZip\wzunzip -o "C:\Database.bak.zip" "C:\Database"';
EXEC master..xp_cmdshell 'xcopy "C:\Database.bak.zip" "\\networkshare\Backups" /Y'

Answer 2

xp_cmdshell is one way, although it isn't ideal since enabling it makes the server less secure.

My open source project, SQL Server Compressed Backup , does what you are looking for in one step:

msbp.exe backup "db(database=model)" "zip64" "local(path=\\server\share\path\model.full.bak.zip)"

The installation of SQL Server Compressed Backup is just "xcopy" deployment -- there is nothing to install/uninstall, ideal if you just need to do this once.

It uses zip64 since the standard zip format has a 4 GB limit. Alternative compression formats available are gzip and bzip2 which have no limits.

Answer 3

Why not using such simple tools like SqlBackupAndFtp ? They do exactly what you need (sql backup + moving to remote location) with a simple interface and you don't need to write any scripts.
