Project context
Fictional archive Alder backs up synthetic document metadata and generated blobs into a dedicated local directory. No real organizational data or cloud accounts are required.
Setup prerequisites
- Create synthetic metadata and generated blob fixtures.
- Provide isolated source backup and restore directories.
Preceding work
Complete these dependencies, or supply their agreed outputs before taking this ticket.
Acceptance criteria
- Matching verified files may be reused
- Partial files are recopied
- Resume retains original snapshot identity
Implementation constraints
- Reuse decisions require digest agreement.
Verification to include
- Resume with valid copied file
- Resume with truncated file
Deliverables
- Copy-resume coordinator and cases
Rollout and recovery
Start a new isolated backup if snapshot identity is lost.
Value of the work
For the engineer: Practice consistent snapshots and recoverable restoration.
For the team: Inspect whether backup success can be substantiated by a usable restore.
Evidence boundaries
Outcome Evidence: Tests, patches, and runbooks are requested deliverables. They become Outcome Evidence only through a qualified Mission and immutable Evidence IDs.
Ownership Evidence: Independent adaptation must be observed under a declared verification policy and cite immutable Evidence IDs. Completing a planning ticket establishes no Ownership Evidence.
