What Datum Storage is
Datum Storage is a decentralized cloud storage service on the Datum Network, with access through Android, iOS, and an API. Datum Drive adds a virtual hard disk to a computer that behaves like a folder. The service says files are encrypted end to end and that users keep the key. Storage accounts are linked to a Datum Identity, which requires email and phone verification to create. Datum is designed for the S3 API format and custom S3 endpoints. After account setup, users receive a URL and key and secret credentials corresponding to S3 credentials; Datum recommends Signature Version 4 when backup software offers a choice. Arq Backup for Mac and Windows is listed as tested, while Duplicati, Duplicity, and Duplicacy are listed as compatible but untested. The Datum ID app is listed for managing credentials and usage. A free plan provides 1 TB for the first year. Additional storage is listed at US$3.99 per terabyte per month, but purchasing it and the mobile workflow are described as coming soon.
