Abstract
A method, apparatus and database system restore tenant data in a multi-tenant environment. The method comprises: logging a plurality of tenants' requests to the database; with respect to a particular tenant who requires restoring tenant data, acquiring a log of events which affect contents of the database and start from a particular backup point; and only restoring in the database data of the particular tenant to the particular backup point, according to the acquired log of events. When a tenant performs a wrong operation on the database and wishes to roll back to a backup point, only information of the particular tenant in the database is changed into the information at the backup point, without affecting other tenants.
