You can restore Azure Cosmos DB database containers from the most recent backup or a specified time. You can restore the database containers to the same cloud account or to a different cloud account.
Note: If the partition key was not present for a container during backup, then after restore, an empty string is added to these containers. This is a Microsoft SDK limitation.
You can perform any of the following restore operations:
Restore to the same cloud account
You can restore the selected databases and containers to the same cloud account .
The restore operation will overwrite the source containers on the database.
Restore to a different cloud account
You can restore the selected databases and containers to a different cloud account on the same or different Azure subscription. The software will create the database during restore if it does not exist.
You can also restore the databases and containers with the same name or a different name.
Redirect to a different Cosmos DB account
You can restore the selected databases and containers to a different Cosmos DB account on the same or a different Azure subscription.
