Errors 9518 and 9519 with code 0x8004010f are reported by MSExchangeIS when FastBack for Microsoft Exchange opens a database.
When FastBack for Microsoft Exchange opens a database, that database is mounted onto a Recovery Storage Group. During the mounting operation, Exchange recognizes that the database is restored from a backup and needs to roll in the logs. After the logs are rolled in, the database is dismounted and remounted.
