Azure长期每日备份配置问题：如何将周备份改为日备份？

Got it, let's clear up the confusion here. The key thing to know is that Azure Backup splits backup policies into two distinct parts:

• Short-term retention policy: This is where you set up daily backups for immediate recovery needs.
• Long-term retention (LTR) policy: As you noticed, this only supports weekly, monthly, and yearly retention schedules—this is for archiving backups over longer periods, not daily operational backups.

Here's how to set up daily backups properly:

Step 1: Navigate to your Backup Vault and Backup Item #

1. Open the Azure Portal and go to your Recovery Services Vault.
2. In the left pane, under Backup, select Backup Items.
3. Choose the type of resource you're backing up (e.g., Azure Virtual Machines) and select the specific item you want to configure.

Step 2: Edit the Backup Policy #

1. On the backup item's overview page, click Backup Policy (it'll show your current policy name).
2. In the policy editor, you'll see two sections: Short-term retention and Long-term retention.
3. For Short-term retention:
   • Set the Backup frequency to Daily.
   • Choose the time of day you want the backup to run.
   • Specify how many days you want to retain these daily backups (e.g., 30 days for short-term recovery).
4. Adjust the Long-term retention settings as needed (this is optional if you only need daily short-term backups).
5. Click Save to apply the changes.

Important Notes #

• If your existing policy doesn't have a short-term retention configured, you'll need to enable it first—this is where daily backups are managed.
• The long-term retention policy doesn't replace short-term backups; it adds an extra layer for retaining older backups (e.g., keep weekly backups for 6 months, monthly for 2 years).
• For some resources like Azure SQL Database, the policy structure might look slightly different, but the core logic of short-term vs long-term retention still applies.
