Data Protection
SWR takes different measures to keep the data stored in SWR secure and reliable.
Measure |
Description |
Reference |
---|---|---|
Transmission encryption (HTTPS) |
To ensure secure data transmission, SWR supports only HTTPS. |
|
Static data encryption |
SWR Enterprise Edition uses Key Management Service (KMS) to encrypt images. After OBS bucket encryption is enabled, KMS keys are used to automatically encrypt images uploaded to OBS buckets. This will improve data security. |
/ |
Data redundancy |
By default, SWR user metadata and image data are stored in multiple AZs in the same region. If one AZ becomes unavailable, data can still be properly accessed from the other AZs. The multi-AZ storage is ideal for scenarios that demand high reliability. |

Data integrity verification (SHA256) |
During image push or pull, data may become inconsistent due to network hijacking, caching, and other reasons. SWR verifies data consistency by calculating the SHA256 value when data is uploaded or downloaded. |
|
Cross-region replication |
You can configure cross-region replication rules to automatically, asynchronously replicate images from a source repository to a destination repository in another region. This provides you with disaster recovery across regions, catering to your needs for remote backup. |
|
Image retention policy |
You can keep multiple tags of an image for quickly retrieving and restoring an image tag, or recovering data from both accidental actions and application failures. |
