PROVIDING DATA BACKUP

Examples relate to providing data backup for a multi-tenant application. One example enables determination that a first data set for a first tenant from the application should be backed up and determination, independently from determining the first data set should be backed up, that a second data set for a second tenant from the application should be backed up. Responsive to determining the first data set should be backed up, a first portion of the first data set stored at a first data resource of a first type may be accessed via a first adaptor for the first type of data resource, and a second portion of the first data set stored at a second data resource of a second type may be accessed via a second adaptor for the second type of data resource. The accessed portions of the first data set may be stored.
