How to configure Short-term RetentionShort term retention for Hyperscale databases can be configured via Portal, PowerShell, Azure CLI and REST API. If your data protection rules require that your backups are available for an extended time (up to 10 years), you can configure long-term retention (LTR) for both single and pooled databases. Suppose the same idle database has its retention increased from 7 days to 14 days in the middle of the month. If you delete a server, all databases on that server are also deleted and can't be recovered. If there is no PITR or LTR backup storage consumption, these meters won't be visible.

I will create this point-in-time recovery for our SQL database from 7 days to 30 days. tiers will be migrated to your Hyperscale databases as well. Here's another example. In addition to his continued work in IT, Posey has spent the last several years actively training as a commercial scientist-astronaut candidate in preparation to fly on a mission to study polar mesospheric clouds from space. Upon point-in-time restore, databases also receive DBCC CHECKDB integrity checks. The same basic principle also applies to disk-based backups and cloud-based backups. retention). The organization decided how long it would keep backups based on cost, the amount of time it would take for a backup to outlive its usefulness, and our ability to securely store the backups in the vault. and REST API. More information about retention policy, please refer to this link.

For information about how to change long-term retention periods, see. Here is an example Azure CLI command to configure STR: Starting 4 May 2022, all newly created Hyperscale service tier databases of Azure SQL Database will be billed for short-term backup storage. If you will check the Available backups tab to ensure we have backups available under long-term retention or not, If you have chosen the Basic tier under the DTU model, then the maximum you can set is like 7 days whereas standard and premium tiers offer up to 35 days of retention periods. Backups that are no longer needed to provide PITR within the new retention period are deleted. This article provides examples to modify automated backup settings for Azure SQL Managed Instance, such as the short-term retention policy and the backup storage redundancy option that's used for backups. To learn about the other business continuity solutions for SQL Database, see, For information about how to configure, manage, and restore from long-term retention of automated backups in Azure Blob Storage by using the Azure portal, see, For information about how to configure, manage, and restore from long-term retention of automated backups in Azure Blob Storage by using PowerShell, see.

You can configure backup storage redundancy when you create your database, and you can update it at a later time. It's possible to combine the backup storage redundancy change with the operation to update the service-level objective (SLO). Long-term retention feature copies backups from automatic backups that run automatically for all Azure SQL databases and save them to BLOB storage as per your defined LTR policy. During a recovery, BRMS uses the latest full backup and any subsequent incremental backups to restore that control group or backup item to its most current status. For everyone else, though, backup retention should be based on both practicality and operational requirements. In the General Purpose service tier, the provisioned data storage is less expensive than the price of the backup storage. Now we have enough scope of increasing retention period from 7 days to 35 days as per our need as shown in the below Meters will show up only if backup storage consumption exists. Change the PITR backup retention and differential backup frequency for active databases by using the following example: To change the PITR backup retention and differential backup frequency for active databases, use the following PowerShell example: For more information, see Backup retention REST API.

Although deleting and re-creating a database might save storage and compute costs, it might increase backup storage costs. Some examples of situations where you may wish to pull data from archives would be for accidental deletion, data corruption, or maliciously effected files. The protection is immediate even if the Hyperscale database was created with a large amount of data via copy or restore. If you increase the current retention period, you don't immediately gain the ability to restore to older points in time within the new retention period. Prior to going freelance, Posey was a CIO for a national chain of hospitals and health care facilities.

Database backups are an essential part of any business continuity and disaster recovery strategy because they help protect your data from accidental corruption or deletion. This example copies a Hyperscale database to a new database by using Gen5 hardware and two vCores. Charges for short term backup storage will be reflected in your June 2022 statement.Monitor Hyperscale backup storage consumptionIn Hyperscale, Data storage size, Data backup storage (snapshot backup size) and Log backup storage (transactions log backup size) are reported via Azure Monitor metrics. Geo-restore is disabled if a database is created with locally redundant or zone-redundant backup storage. For an overview of database copy, see Copy a transactionally consistent copy of a database in Azure SQL Database. You can use automatically created backups in the following scenarios: Restore an existing database to a point in time within the retention period by using the Azure portal, Azure PowerShell, the Azure CLI, or the REST API. But if you've configured long-term retention for a database, LTR backups are not deleted. Possible values for -BackupStorageRedundancy are Geo for geo-redundant, Zone for zone-redundant, Local for locally redundant, and GeoZone for geo-zone redundant backup storage.
