Sql 备份到 url - azure blob 差异

Sql backup to url - azure blob differential

我有一个 v large dB 250 gb,我已经使用下面的方法备份到 azure blob...

BACKUP DATABASE [TestDB] TO URL = 'https://cloudspacestorage.blob.core.windows.net/backups/Testdb.bak'
WITH CREDENTIAL = 'Backupcredential', STATS = 10 GO

我现在需要再做一次,有什么方法可以做差异备份,例如仅自上次备份以来的更改

谢谢

正如 Larnu 所说,您可以调用 Differential Backups (SQL Server)

由于您已将数据库完全备份到 Azure Blob 存储,并且满足以下条件:

BACKUP DATABASE [TestDB] 
TO URL = 'https://cloudspacestorage.blob.core.windows.net/backups/Testdb.bak'
WITH CREDENTIAL = 'Backupcredential', STATS = 10 GO

SQL Server Backup to URL 开始,Bcakup to URL 支持您创建差异备份。

因此您可以像这样对 Azure Blob 进行差异备份:

BACKUP DATABASE [TestDB] 
TO URL = 'https://cloudspacestorage.blob.core.windows.net/backups/Testdb.bak'
WITH DIFFERENAL 

希望这对您有所帮助。
