<p><strong>Data Persistence</strong></p> <p>Data persistence: no less than 99.9999% (calculated by service cycle, each service cycle is a natural month. Less than one month is not be calculated. For every 10000 key in Redis cluster, the probability of losing data per month is 99.99%, i.e., only 1 key in Redis cluster per month may lose data.</p> <p>&nbsp;</p> <p><strong>Data Availability</strong></p> <p>Service availability: not less than 99.967% (formula is that available time for single Redis cluster for each service cycle/ (available time for single Redis cluster for each service cycle + unavailable time for single Redis cluster for each service cycle).</p> <p>Additional:</p> <ul> <li>Calculated by service cycle, each service cycle is a natural month. Less than one month is not be calculated. Statistical unit is per Redis cluster per minute.</li> <li>Unavailable time: means that all connections request to the specified Redis cluster fail during 1 minute period. Continuing 5 minutes or longer will be included in the unavailable time, while less than 5 minutes will not. Unavailable time does not include routine maintenance, caused by user behavior , the third party or force majeure.</li> </ul> <p>&nbsp;</p> <p><strong>Data Destruction</strong></p> <p>If you voluntarily delete your own data or the data need to be destroyed because of overdue, corresponding data will be thoroughly removed from disks and memory on the&nbsp;physical server so that it can not be recovered.</p> <p>The physical disk of these&nbsp;physical servers will be erased by demagnetizing, before discarding, outsourcing, servicing, or reselling. The whole process will be monitored and recorded over a long period of time. All the Processing log will be audited periodically to meet security compliance requirements.</p> <p>&nbsp;</p> <p><strong>Data Privacy</strong></p> <p>Ensure different customer could not access each other&#39;s data by isolation policy.</p> <p>&nbsp;</p> <p><strong>Right to Know</strong></p> <p>Customers have the right to know the location of the datacenter, the location of the data and backup sets, and the quantity of data backup sets.</p> <p>Datacenter will comply with local laws and regulations, you could contact with the Customer Service Center for more detailed information.</p> <p>All of the data, application logs and behavior logs belong to customer will not be available to any other the third party, unless required by the laws, regulations, or regulatory authorities, auditing requirements. In addition to statistical analysis the running state of our own Redis cluster service, we can not access or leak any customer privacy information.</p> <p>&nbsp;</p> <p><strong>Data Auditability</strong></p> <p>Cooperating with government supervision departments, security compliance, auditing or investigation, in accordance with the law procedures and formalities, we can provide customers&#39; information including operation log, running log, maintenance log and so on to meet auditing requirement.</p>
