You don't incur charges until the database restore is complete. The restored database is charged at normal rates, based on its service tier and compute size. When the restore is complete, it creates a new database on the same server as the original database. When you're restoring a database into an elastic pool, ensure that you have sufficient resources in the pool to accommodate the database. The restore request can specify any service tier or compute size for the restored database. You can restore any database to an earlier point in time within its retention period. You can recover by using the Azure portal, PowerShell, or the REST API. The subscription or resource group ownerįor more information, see Azure RBAC: Built-in roles.A member of the Contributor role or the SQL Server Contributor role in the subscription or resource group that contains the logical server.To recover by using automated backups, you must be either: Max # of concurrent requests being submitted Max # of concurrent requests being processed These limitations apply to any combination of point-in-time restores, geo-restores, and restores from long-term retention backup. Most database restores finish in less than 12 hours.įor a single subscription, you have the following limitations on the number of concurrent restore requests. When there are many requests, the recovery time for individual databases can increase. A prolonged outage in a region might cause a high number of geo-restore requests for disaster recovery. The number of concurrent restore requests that are processed in the target regionįor a large or very active database, the restore might take several hours.The network bandwidth if the restore is to a different region.The amount of activity that needs to be replayed to recover to the restore point.The number of transaction logs involved.Several factors affect the recovery time to restore a database through automated database backups: If the actual amount of used space is less than the amount of storage included, you can avoid this extra cost by setting the maximum database size to the included amount. The extra cost happens when the maximum size of the restored database is greater than the amount of storage included with the target database's service tier and service objective.įor pricing details of extra storage, see the SQL Database pricing page. When you're using the Standard or Premium service tier in the DTU purchasing model, your database restore might incur an extra storage cost. Database restore operations don't restore the tags of the original database.You can't overwrite an existing database during restore.If you configured long-term retention (LTR), you can also create a new database from any long-term retention backup on any server. Create a new database on any server in any other region, recovered to the point of the most recent replicated backups.Create a new database on any server in the same region, recovered to the time of a recent backup.Create a database on the same server, recovered to the deletion time for a deleted database.Create a new database on the same server, recovered to a specified point in time within the retention period.The following options are available for database recovery through automated backups: This built-in capability is available for all service tiers and compute sizes. For Azure SQL Managed Instance, see Restore a database from a backup in Azure SQL Managed Instance.Īutomated database backups help protect your databases from user and application errors, accidental database deletion, and prolonged outages. The ability to tag and save previous versions of changed files rather than just replace during backup would be great but as long as it does 1 and 2, I won't be greedy.This article provides steps to recover any database from a backup in Azure SQL Database, including Hyperscale databases. Simply because experience has taught me I can't rely on backup file formats to be accessible when needed. I have terabytes of external hard drive space where a good 60-70% is duplicate files because it's too easy to miss files with the brunt force method of incremental backup so each time I backup I do the whole thing. does a straight copy, the same as if files were drag and dropped, instead of backup to files formatted to be only opened by that particular backup software.Unfortunately, over time, this wastes quite a bit of memory.ĭoes anyone know of backup software that: Having learned my lesson the first time I always keep a straight copy. The last time was in 2012 with the HP backup software that came bundled with my computer. I backup my data fairly reliably but three times I have been put into a situation where when the backup was needed the backup program failed and I was told the software was no longer being supported.
