Data files and metadata are backed up nightly and directly in Amazon Web Service's (AWS) S3 buckets.
Amazon S3’s standard storage is:
- Backed with the Amazon S3 Service Level Agreement for availability.
- Designed for 99.999999999% durability and 99.99% availability of objects over a given year.
- Designed to sustain the concurrent loss of data in two facilities.
AWS S3 content is region bound and in order to recover from an AWS EU region failure, we’ve enabled cross region replication for AWS S3. So, all files stored on the AWS EU region are also replicated over to the AWS US region.
Furthermore, all AWS S3 files are replicated over to CloudSigma as part of the file backup process. This means that in the event of a multiple AWS region failure, core figshare services once restored on CloudSigma can start accessing the files immediately.
As an extra layer of security, figshare has also joined DPN, to offer further assurances that public data will be preserved in safe hands under the stewardship of DPN. In the unlikely event of both AWS and Cloudsigma failures, figshare can restore user public content from the DPN network. For more details see our Preservation Policy.
