1. A computerized method of performing backup of databases and associated logs with one schedule such that a backup of both a database and its associated log can be restored or recovered to a desired point in time, the method being executed by a processor in communication with memory storing instructions configured to cause the processor to:
receive, at a virtual data management system configured to protect an application, a backup request, the backup request associated with a backup type defined by a service level agreement, the service level agreement defining a schedule for backing up a database associated with the application, the service level agreement including a combined schedule for backing up both data stored in the database and log data associated with the database, wherein the service level agreement is defined for the virtual data management system configured to protect the application, the backup type including a database backup type, a log backup type, and a composite database backup and log backup type; receive at a first time, from a host agent running on a database server, a first database backup and a first associated snapshot of the database when the backup type comprises a database backup type; assign a first identifier to the first database backup and the first associated snapshot, the first identifier including a first composite backup identifier indicative of a first set of database backups and log backups that share a first dependency relationship; receive at a second time, from the host agent running on the database server, a log backup and a second associated snapshot of the log backup when the backup type comprises a log backup type; assign a second identifier to the log backup and to second associated snapshot, the second identifier including a second composite backup identifier indicative of a second set of database backups and log backups that share a second dependency relationship, the second composite backup identifier equal to the first composite backup identifier when the first time comprises a most recent prior database backup time to the second time; receive at a third time from the host agent running on the database server a composite database and log backup and a third associated snapshot of the database and the log backup when the backup type comprises a composite database and log backup type; and assign a third identifier to the composite database and log backup and to third associated snapshot, the third identifier including a third composite backup identifier indicative of a third set of database backups and log backups that share a third dependency relationship, thereby performing data backup of databases and associated logs with one schedule such that a full backup of both a database and its associated log can be retrieved for a desired point in time. |
