What Are the Storage Classes Supported by OBS?

OBS has the following storage classes: Standard, Infrequent Access, and Archive. In such a manner, OBS comprehensively meets customers' requirements on storage performance and costs.

  • OBS Standard features low access latency and high throughput. It is applicable to storing frequently-accessed (multiple times per month) hotspot or small files (< 1 MB) requiring quick response. The application scenarios include big data, mobile applications, hotspot videos, and social media images.
  • OBS Infrequent Access is applicable to storing semi-frequently accessed (less than 12 times a year) data requiring quick response. The application scenarios include file synchronization or sharing, and enterprise-level backup. It provides the same durability, access latency, and throughput as OBS Standard but at a lower price. However, OBS Infrequent Access has lower availability than OBS Standard.
  • OBS Archive is applicable to archiving rarely-accessed (once a year) data. The application scenarios include data archiving and long-term data retention for backup. OBS Archive is secure, durable, and inexpensive, which can replace tape libraries. However, it can take up to hours to restore data from OBS Archive.
