通过Blob存储帐户的Azure Sql Server每日备份

Question

如何在Azure blob存储容器上安排Azure Sql数据库的每日自动备份。

Answer 1

You can't create or schedule Backups (.bak file format) of a managed Azure SQL Database.

However, it is possible to create an export (.bacpac file format). Such an export process can be started with Powershell and this Powershell Script can then be time-controlled with a Powershell-Runbook.

I'm using this script for exactly the same purpose. It will create your database "backups" in the blob storage and it will also take care of how long backups are kept.

The full process is available here

Answer 2

For Azure SQL Server (IaaS) : You can configure back up to a storage account using SSMS (SQL Server Management Studio) as shown here in " Database backup to URL "

This method was also included in an earlier answer that suggested using the tool SQLBackupandTFP here .

For Azure SQL Database (PaaS): Built-in backups are auto configured and work as such... "Seven days of automated backups of your databases are copied to RA-GRS Standard blob storage by default. The storage is used by weekly full backups, daily differential backups, and transaction log backups copied every 5 minutes. The size of the transaction log depends on the rate of change of the database. A minimum storage amount equal to 100% of database size is provided at no extra charge. Additional consumption of backup storage will be charged in GB/month." - Automated Backups-Storage Costs

Automating copy of the database and export to the blob storage container is an option as well. However you are incurring the extra cost for the storage with this method--assuming it is only used for this purpose.

There is a good comparison of the two here .
