Atomic Safety Protocol.
A restore should never leave your network half-changed. Atomic Safety Protocol is how every NET Backup Vault restore is treated as a single, all-or-nothing operation: it either completes in full and correctly, or it makes no change at all. No partial writes. No corrupted in-between state. No guesswork.
What "atomic" means for a restore
In computing, an operation is atomic when it cannot be partially done. It happens completely, or it does not happen at all. There is no observable middle state.
Recovery is exactly where that property matters most. A restore that fails halfway, after writing some VLANs but not the firewall rules that depend on them, can leave a network in a state that never existed before and is worse than the problem you were fixing.
Atomic Safety Protocol removes that risk. A restore is one transaction with a clear contract: succeed entirely, or revert entirely.

%Every restore snapshots your live config first. If anything fails mid-restore, automatic rollback returns your network to its exact pre-restore state. Zero partial writes. Zero risk.
Four guarantees
behind every restore
All or nothing
It completes in full, or it changes nothing
A restore is treated as a single operation. There is no in-between state where some firewall rules applied and others did not. Either the whole change lands cleanly, or your network stays exactly as it was.
Validate first
Nothing is written until the request checks out
Pre-flight validation and an optional dry-run preview confirm the target is reachable and the backup is compatible before any live setting is touched. You see what would change before you commit to changing it.
Snapshot
Your live state is captured before the first write
The current configuration is recorded as a rollback checkpoint at the start of every restore. That checkpoint is what makes a clean, automatic reversal possible.
Rollback
Failure reverts you, automatically
Power loss, an API timeout, or a rejected change mid-restore all trigger the same response: the engine reapplies the checkpoint and your network returns to its exact pre-restore state.
One safety sequence,
every single time
Whether you restore one firewall rule or an entire organization, the same four steps run underneath. The protocol is not optional, and it is not something you have to configure.
Pre-flight validation
Before a single setting is written, NET Backup Vault checks that the target organization and networks exist, are reachable, and are compatible with the backup. Nothing is applied during this phase.
Snapshot first
NET Backup Vault captures your current live configuration as a rollback checkpoint. This is the exact state your network will return to if anything goes wrong.
Apply
Each selected setting is pushed back to the Meraki Dashboard in sequence. Long-running restores report live progress so you always know which step is executing.
Verify, or roll back
Every change is confirmed against live state. If any step fails midway, the engine automatically reapplies the snapshot and returns your network to its exact pre-restore state. No partial writes are left behind.
Rollback checkpoints are retained for a limited window after a restore completes, so you can also reverse a successful restore after the fact while the checkpoint is still available.
What we can protect, and what no tool can
Atomic Safety Protocol guarantees the integrity of what is restored. It does not, and cannot, expand what is possible to capture in the first place. Every Meraki backup tool, including NET Backup Vault, can only read and write what the Meraki Dashboard API exposes.
We think you deserve to know where that line is. A truly complete Meraki backup remains challenging even on the latest API, for reasons that sit with the platform, not the backup tool:
Meraki's Dashboard API still does not have full feature parity with the Dashboard UI.
Some Dashboard settings remain UI-only and have no API endpoint to read or write them.
Beta endpoints frequently appear before they stabilize, so coverage shifts over time.
Newer product families (MV cameras, MT sensors, MG cellular) are still expanding their API coverage.
NET Backup Vault backs up everything the API does expose, across 19+ configuration types, and tracks new endpoints as Meraki ships them. Anything Meraki keeps UI-only sits outside the API and therefore outside any automated backup. We would rather state that plainly than imply a coverage we cannot honestly deliver.
Restore without the held breath.
