In addition, Amazon S3 Standard, S3 Standard-IA, and S3 Glacier are all designed to sustain data in the event of an entire S3 Availability Zone loss. For example, if you store 10,000,000 objects with Amazon S3, you can on average expect to incur a loss of a single object once every 10,000 years. This durability level corresponds to an average annual expected loss of 0.000000001% of objects. Any uploaded documents are also immediately copied to a client specific and encrypted Amazon S3 bucket with access policies configured in a way that only the client services can access those documents.Īmazon S3 is designed to provide 99.999999999% durability of objects over a given year. Recently uploaded documents are cached on the local EBS volume of the application server for anti-virus scanning and faster access. If additional tests by the client are requested this can result in a longer DR drill, and needs to be quoted on, otherwise this will be charged at our agreed standard hourly rate. This process usually takes up to one day. A dedicated client contact can be involved in the DR drill if this is desired and perform their own verifications. We then verify that the instance is accessible and perform standard operations including checking case and case data availability within the system. Our DR drill involves setting up replacement EC2 and RDS instances, recovering the RDS DB to an agreed point in time (according to RPO), and connecting the new EC2 instance to the recovered RDS instance as well as to the S3 document store. If a client requests dedicated DR drills for their particular data this can be quoted and added to the service offering at an additional cost. Generally we pick a random client and perform such a DR drill, however clients can opt out of this process. Polonious performs regular Disaster Recovery (DR) drills.
