Point-in-time snapshots for S3 buckets and DynamoDB tables. Reserved on PyPI while the source codebase is prepared for open-source publication.
Project description
aws-snapshot
Point-in-time snapshots for S3 buckets and DynamoDB tables.
This package name is reserved on PyPI while the source codebase
(currently developed as
GNS-Science/nzshm-backup)
is being prepared for open-source publication.
The first functional release will be 0.1.0.
What it will do
- DynamoDB tables — backed up via DynamoDB Point-in-Time Recovery
(
ExportTableToPointInTime). Each backup captures table state at a chosen timestamp; restore creates a new table populated from the snapshot. - S3 buckets — backed up via incremental ETag-based sync driven by S3 Inventory. The combination of point-in-time inventory manifests and S3 object versioning on the backup bucket gives point-in-time restore semantics without the cost of full block-level snapshots.
- Cross-account isolation between source and backup accounts is first-class.
- Pricing target: approximately 97% cheaper than AWS Backup for BLOB-heavy workloads.
Out of scope
- EBS / RDS / Aurora snapshots (use AWS Backup or native snapshots for these).
- WORM / compliance-mode locking.
Tracking
Open-source migration progress is tracked at GNS-Science/nzshm-backup#48.
