When choosing a tool for long-term agent memory, ask for a restore demonstration as well as a recall demonstration. Can you recover an approved fact on a clean installation, find the record that supports it, and get the agent to use it without copying the answer into the prompt?
This guide proposes a small backup-and-restore drill. It is an evaluation procedure, not a measured benchmark or a claim that every memory product behaves the same way. Use synthetic records and an isolated test environment throughout.
Start with the result you need, before choosing a backup mechanism. Write down:
Treat these as acceptance criteria. Do not assume an export, a synchronization command, and a restorable backup provide the same result. Test the exact operation you plan to use.
For a fictional project called Lantern, the recovery contract might be: “A fresh agent session can recover the approved export label, identify its source record, and avoid retrieving a retired label.” That is more useful than “the backup command returned success.”
Store three synthetic records through the candidate tool’s supported interface:
| Record | Example | What to inspect after restore |
|---|---|---|
| Current convention | Lantern export files use the label amber-otter | Exact statement and project scope |
| Decision with rationale | Keep exports manual until the test queue is ready | Rationale and source metadata |
| Superseded convention | The previous label was silver-finch | Correction or retirement state |
Use the tool’s documented workflow to mark the old convention as superseded or retired. If it has no such workflow, document the alternative your application uses. The example labels are deliberately arbitrary; they make it easier to distinguish retrieved information from a plausible guess.
Keep the expected answers in a separate evaluation sheet. Do not include that sheet in the restored agent’s prompt or accessible workspace.
Before making the backup, list its intended contents. Afterward, inspect it through a supported reader or restore preview. Compare the observed records with your list.
For a concrete product example, the PLUR repository documentation distinguishes personal and shared git synchronization. Personal sync can include private-visibility engrams and requires a private remote. Shared sync filters for shared-family scopes and non-private visibility. The documentation also says scope: local records are excluded from remote commits. These distinctions matter when deciding which records a recovery drill should expect to find.
Do not infer backup coverage from a label such as “private” or “local.” Read the documented behavior for the operation you will actually run, then verify the resulting artifact.
Leave the original store intact. Use a disposable environment that cannot silently read the original store, its cache, or its remote connection.
Follow the candidate tool’s documented restore procedure. Record the application version, backup artifact, required configuration, and any manual steps. Keep secrets out of the evaluation sheet.
Check recovery in layers:
amber-otter when asked to describe Lantern’s export naming convention?A failure at one layer should remain visible even if another layer succeeds. Finding the record in a file is not the same acceptance criterion as seeing the agent use it.
Run the same task in a second disposable environment without the restored fixture. Also ask an unrelated project question in the restored environment.
Your desired outcome is that the restored environment can identify Lantern’s convention, while the empty environment cannot recover the arbitrary label from memory. For the unrelated question, inspect whether Lantern records were retrieved and whether that matches your intended scope policy.
These controls do not prove universal reliability. They help you identify accidental access to the original store, answer leakage from the test prompt, and unexpected cross-project recall in this specific drill.
Use a compact worksheet:
| Check | Pass condition |
|---|---|
| Backup coverage | Intended records present; intended exclusions respected |
| Record integrity | Statements and required metadata match the fixture |
| Clean-room restore | No dependency on the original store |
| Recall and use | Current convention retrieved and applied in a fresh session |
| Correction preservation | Retired convention does not become the active answer |
| Operator handoff | Another operator can follow the documented procedure |
Choose your own acceptable recovery time and manual effort. Measure them during the drill instead of borrowing a vendor’s headline number. If the procedure depends on an undocumented step, add that step to your operating instructions and repeat the affected check.
The useful question is not merely “Which tool remembers?” It is “Can we recover the knowledge we intended to keep, with its boundaries intact, and show that our agent can use it?”
For the broader selection process, see the agent-memory acceptance checklist. If the restored record is wrong rather than missing, use the incorrect-memory recovery workflow.
