You set up air gapped efs protection by copying file data to a locked vault. This isolated vault blocks network paths and stops admins from deleting backups. Teams often build this setup using native cloud backup vaults and cross-account rules. When permissions are too broad, a bad actor or script can wipe out production files. Overly broad roles also let attackers delete recovery points in the same account.
How to build air gapped efs protection
First, you create a separate cloud account just for holding backup copies. This backup account has no direct network path to your main production network. Next, you set up an automated backup plan in your primary account. The plan takes snapshots of your shared file system on a set schedule. It then copies those snapshots across accounts into the isolated vault.
Inside the backup account, you turn on a vault lock rule. This lock stops any user, even the root admin, from deleting saved snapshots. The lock stays active until a set retention timer runs out. You also attach strict role rules to the file system itself. These rules check the identity of every compute node or user before mount time. Encryption keys in a separate key service lock the data at rest.
What native file isolation solves and what it misses
This native backup architecture protects your team against total data loss from ransomware. If an attacker encrypts your live files, your locked copies stay safe. Network isolation also blocks outside traffic from reaching the mount targets directly. Identity rules make sure only approved compute instances can mount the file share.
Still, vault locks and mount rules only control who gets in at the start. They do not inspect what an approved user or script does inside a session. Once an engineer logs into a host with mount rights, they have full reach. A single bad command can delete thousands of live files before the next snapshot. Native file logs also struggle to link shell commands to specific human users. Also, reading raw files can expose sensitive emails, phone numbers, or card numbers.

Managing live host sessions near shared file systems
To close this gap, teams must govern the human and service sessions on hosts. Instead of giving engineers standing shell permissions, teams should scope every task. Each command run against a mounted drive needs an audit trail tied to an individual. Teams also need ways to review risky delete commands before they run in production. Controlling live commands keeps your primary data safe while backups wait in the vault.
Add runtime guardrails and masking beside your databases and APIs
Login rules, role grants, and CI checks govern who connects to your stack. Yet any allowed script, engineer, or AI agent still runs commands with the full scope of its role. For workloads on Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes, SSH, or internal HTTP services, hoop.dev sits inline in the protocol beside the service as an open-source proxy, a sidecar for your database or API. On every production query an agent or human runs, hoop.dev decides whether to pass, mask, block, or escalate it for review.
Before a query runs, hoop.dev guardrails check the statement against your rules, an AI Analyzer you configure can score intent or hold risky calls for human approval, and hoop.dev data masking rewrites sensitive fields in responses in memory. Explore the MIT-licensed project on GitHub.
Frequently asked questions
What makes a cloud file backup truly air gapped?
A true air gap keeps backup copies in a separate account with no network link. It also uses a strict lock rule so no admin can delete them early.
Can a root user delete locked file system backups?
No, once you seal a compliance vault lock, not even the root user can remove it. The snapshots stay safe until the timer you set runs out.
Why do we need session controls if our backups are locked?
Restoring huge file shares from a vault takes hours and causes long app downtime. Session controls stop bad commands on live hosts so you avoid slow restores.
