Experimental. Originated in the Payblocks template, now maintained as a standalone package. Running in production at 20+ projects from TRWK agency. Feedback and PRs welcome.

@trieb.work/payload-plugin-backup-mongodb

A Payload CMS v3 plugin for MongoDB only — not Postgres, SQLite, or other database adapters. It handles Mongo + media backup, restore, and scheduled retention with zero meta-database and a built-in admin UI. Backups live in Vercel Blob Storage (default) or AWS S3 / S3-compatible stores (R2, MinIO, etc.), so a fresh install can list and restore any prior backup without bootstrapping a database first.

A first-class Backups section lives right below the Payload dashboard: browse every archive sorted by creation time, see at a glance which host and database it belongs to, whether media is bundled and how big it is, then download, restore or delete any backup with one click. Read more on how it originated at TRWK> Case Study.

Highlights

• No meta database. Every backup is self-describing in its blob name (type---db---host---{collectionCount}-{timestampMs}.{ext}). A brand new project can list and restore any backup straight from blob storage.
• Scheduled (cron) and on-demand backups. Wire /api/backup-mongodb/cron/run to Vercel Cron or any HTTP scheduler. Retention is configurable (N most recent cron backups are kept; older ones are pruned automatically).
• Full database coverage. Dumps every MongoDB collection via the Payload mongoose adapter — including hidden system collections like users, payload-preferences, payload-migrations. Individual collections can be excluded per backup from the UI or via API.
• Optional media bundling. Cron or manual backups can include Payload media blobs in a .tar.gz archive alongside the MongoDB dump.
• Restore with filters. Restore any backup with an optional collection blacklist and mergeData upsert mode. Partial restores keep the running admin session / tasks collection intact.
• Native admin dashboard. Adds a BackupDashboard widget to the Payload admin (afterDashboard): list / sort / filter / search backups, trigger manual backups or restores, configure retention and storage, and live-poll long-running tasks.
• Payload REST, not Next.js route files. All endpoints are registered as Payload custom endpoints and served by the default /api/[...slug] handler — you do not add app/.../route.ts files for this plugin.
• Pluggable blob storage. Uses BLOB_READ_WRITE_TOKEN by default (the same store you often use with @payloadcms/storage-vercel-blob), or point backups at a dedicated Vercel Blob store in the admin. Alternatively set BACKUP_STORAGE=s3 and use AWS S3, Cloudflare R2, MinIO, etc. Both public and private access stores are supported; a validation step detects which modes the store accepts.
• Resumable long-running tasks. Manual backups and restores are tracked in a hidden backup-tasks collection (TTL, 30 min). The UI polls progress with a short-lived pollSecret so long jobs stay observable even across reloads.
• Tested. Vitest covers archive, backup, restore, task progress, blob I/O, endpoint auth, cron parsing, and blob-name helpers.

Requirements

• Node.js 20.9+ (Node 18 is no longer supported).
• Payload v3+ (same major as your other @payloadcms/* packages).
• MongoDB with Payload’s mongoose adapter (@payloadcms/db-mongodb).
• MongoDB server (any version supported by that adapter).
• A backup target:
  • Vercel Blob: BLOB_READ_WRITE_TOKEN (the default target). Vercel hosting is not required — any Node runtime that can reach Vercel Blob works.
  • S3: BACKUP_STORAGE=s3 plus BACKUP_S3_BUCKET (and optionally credentials). Requires Node 20+ for the optional AWS SDK peer packages. See Choosing a backup target.
• Next.js 15+ and React 19+ (the usual Payload 3 + App Router stack).

Environment variables

| Variable | Required | Purpose | | ------------------------------ | --------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | MONGODB_URI | yes | MongoDB connection string (used by Payload and to label backups with the DB name). | | BACKUP_STORAGE | optional | Backup target: vercel-blob (default) or s3. See Choosing a backup target. | | BLOB_READ_WRITE_TOKEN | for Vercel Blob | Default Vercel Blob store for backups and media. Required when BACKUP_STORAGE=vercel-blob (the default). Can be overridden in admin settings. | | CRON_SECRET | for cron | Bearer token for every /api/backup-mongodb/cron/* call. Vercel Cron can supply this. | | NEXT_PUBLIC_SERVER_URL | optional | Used to label backups with the current host. Falls back to VERCEL_URL when set. | | BACKUPS_TO_KEEP | optional | Default retention for cron backups if the settings document has not been edited. Default 10. | | PAYLOAD_BACKUP_ALLOWED_ROLES | optional | Comma-separated role slugs that may see the Backups dashboard (case-insensitive). Use * to allow any authenticated user. When unset, the plugin falls back to requiring a role with slug admin, or allows everyone when the users collection has no roles field. Overridden by the access plugin option. |

Choosing a backup target (Vercel Blob or S3)

Backups can be stored in Vercel Blob (default) or AWS S3. The S3 target also works with any S3-compatible store — Cloudflare R2, MinIO, etc. — because they share the same API; only the configuration differs, never the plugin code.

Select the target with BACKUP_STORAGE. When unset it stays vercel-blob, so existing deployments are unaffected.

Using S3

S3 is enabled when BACKUP_STORAGE=s3. Install the AWS SDK (declared as optional peer dependencies, so Vercel-only installs don't pull it in):

pnpm add @aws-sdk/client-s3 @aws-sdk/lib-storage @aws-sdk/s3-request-presigner

| Variable | Required | Purpose | | ----------------------------- | -------- | --------------------------------------------------------------------------------------------------------------------- | | BACKUP_STORAGE | yes | Set to s3. | | BACKUP_S3_BUCKET | yes | Target bucket name. | | BACKUP_S3_REGION | optional | Region. Falls back to AWS_REGION, then us-east-1. | | BACKUP_S3_ENDPOINT | optional | Custom endpoint for S3-compatible stores (R2, MinIO). Omit for AWS S3. | | BACKUP_S3_FORCE_PATH_STYLE | optional | Path-style addressing. Defaults to true when an endpoint is set (needed for MinIO and some R2 setups). | | BACKUP_S3_PREFIX | optional | Key namespace prepended to every object (for sharing a bucket). Backups still list/restore by their backups/… name. | | BACKUP_S3_ACCESS_KEY_ID | optional | Access key. Falls back to AWS_ACCESS_KEY_ID. Omit to use the AWS default credential chain (IAM roles, etc.). | | BACKUP_S3_SECRET_ACCESS_KEY | optional | Secret key. Falls back to AWS_SECRET_ACCESS_KEY. | | BACKUP_S3_SESSION_TOKEN | optional | Session token for temporary credentials. Falls back to AWS_SESSION_TOKEN. |

Credentials are optional: when omitted, the AWS SDK's default provider chain is used (environment, shared config, or instance/role credentials — recommended on AWS).

AWS S3

BACKUP_STORAGE=s3
BACKUP_S3_BUCKET=my-payload-backups
BACKUP_S3_REGION=eu-central-1
# Credentials via IAM role (recommended) or:
# BACKUP_S3_ACCESS_KEY_ID=...
# BACKUP_S3_SECRET_ACCESS_KEY=...

Cloudflare R2

BACKUP_STORAGE=s3
BACKUP_S3_BUCKET=my-payload-backups
BACKUP_S3_REGION=auto
BACKUP_S3_ENDPOINT=https://<account-id>.r2.cloudflarestorage.com
BACKUP_S3_FORCE_PATH_STYLE=true
BACKUP_S3_ACCESS_KEY_ID=<r2-access-key-id>
BACKUP_S3_SECRET_ACCESS_KEY=<r2-secret-access-key>

Backups are stored under the same backups/… keys (see Blob naming), so listing and restore work identically across targets. Downloads stream through the plugin's authenticated endpoint, so the bucket does not need to be public.

Note on media: the "include media" option bundles files from your Payload Vercel Blob upload store (BLOB_READ_WRITE_TOKEN). The configurable target above governs where backup archives live only; media is always read from and restored to the upload store, even when BACKUP_STORAGE=s3.

Installation and getting started

Use this flow when adding the plugin to an existing Payload 3 + Next.js app that already has MongoDB and a blob/S3 store configured.

1. Add the package

pnpm add @trieb.work/payload-plugin-backup-mongodb
# npm install @trieb.work/payload-plugin-backup-mongodb
# yarn add @trieb.work/payload-plugin-backup-mongodb

Peer dependencies: @payloadcms/db-mongodb, payload, @payloadcms/ui, next, and react. (all expected in a Payload 3 + MongoDB + Next.js app).

2. Register the plugin

// payload.config.ts
import { buildConfig } from 'payload'
import { backupMongodbPlugin } from '@trieb.work/payload-plugin-backup-mongodb'

export default buildConfig({
  // your db adapter, collections, etc.
  plugins: [
    backupMongodbPlugin({
      // all options optional — see "Plugin options"
    }),
  ],
})

The plugin will register the backup collections, mount the dashboard, and add /api/backup-mongodb/* endpoints. Import paths resolve to a published or linked dist/ build; after local changes to the package, run pnpm build in the plugin repo (or reinstall) so dist/ is up to date.

3. Regenerate types and the import map

So Payload picks up the new admin components and collections:

pnpm payload generate:types
pnpm payload generate:importmap

4. (Optional) Schedule cron backups

Vercel: add a cron in vercel.json. Path must match your API; default is under /api/…:

{
  "crons": [
    {
      "path": "/api/backup-mongodb/cron/run",
      "schedule": "0 3 * * *"
    }
  ]
}

Vercel Cron sends header Authorization: Bearer $CRON_SECRET. Other hosts (k8s, GitHub Actions, etc.): GET the same URL on your schedule with that same authorization header.

Checklist

• [ ] Package installed
• [ ] backupMongodbPlugin in plugins array
• [ ] generate:types and generate:importmap run
• [ ] MONGODB_URI and BLOB_READ_WRITE_TOKEN set in the environment
• [ ] (Optional) CRON_SECRET and cron job (vercel.json) if you want scheduled backups

Start your dev server, open /admin, sign in as an admin, and you should see Backups below the dashboard.

Admin UI

After the first login as an admin user, a Backups section appears below the default Payload dashboard. Day-to-day tasks — create, download, restore, delete, schedule — all happen in the UI below.

Who can see it? The visibility rules, in precedence order:

1. If the plugin is registered with an access function, it wins (see Plugin options).
2. Otherwise, if PAYLOAD_BACKUP_ALLOWED_ROLES is set, it is used as a comma-separated allow-list of role slugs (case-insensitive). Use * for "any authenticated user". Example: PAYLOAD_BACKUP_ALLOWED_ROLES=admin,superadmin.
3. Otherwise, the historical default applies: users with a role whose slug is admin see the dashboard; projects that don't use a roles field at all get the dashboard for any authenticated user.

Scheduled (cron) vs on-demand (manual) backups

• Scheduled / cron backups follow shared settings: retention, media toggle, and collections to skip. Older cron archives are pruned when the keep-count is exceeded. They appear in the list as CRON BACKUP (or similar).
• Manual / on-demand backups are configured per run — per-collection toggles, optional media in a .tar.gz archive. Manual backups are not auto-pruned; use them as checkpoints before migrations.

Selective restore with per-collection preview

Restore opens a preview of the archive before any write. You can restore everything, cherry-pick collections, or skip media from .tar.gz when you only need database rows. Restoring from a different host or database is supported; filters help when cloning production into staging.

Scheduled backup settings

Retention, storage token, and cron collection skip list live in one modal:

• Schedule: when vercel.json is present, the plugin can show a human-readable cron description (via cronstrue).
• Retention: how many cron archives to keep; manual backups are not pruned by this.
• Dedicated backup storage (optional): a separate Vercel Blob read/write token (when BACKUP_STORAGE=vercel-blob) so backups can live in a different store than media. The UI can validate the token and optionally copy existing backups/* objects to the new store. For S3, configure the target bucket via environment variables.
• Collection selection for cron: defaults to all collections, with per-collection opt-out.

Plugin options

type BackupPluginOptions = {
  /**
   * Set to `false` to disable the plugin (no collections, endpoints, or admin UI).
   * Omit or leave unset to keep the plugin active.
   */
  enabled?: boolean

  /** Default cron retention when no value is stored in settings. Falls back to `BACKUPS_TO_KEEP` or `10`. */
  backupsToKeep?: number

  /**
   * Custom access check for admin routes and the dashboard. Overrides the
   * `PAYLOAD_BACKUP_ALLOWED_ROLES` env var when provided.
   *
   * Default (env-based): see the `PAYLOAD_BACKUP_ALLOWED_ROLES` entry in the
   * environment variables table. When neither is configured, the check falls back
   * to a role with slug `admin`, or allows any authenticated user in projects
   * without a `roles` field.
   */
  access?: (user: Record<string, unknown> | null) => boolean
}

HTTP API (Payload REST)

All routes are served by Payload’s /api/[...slug] handler under /api/backup-mongodb/…. The backup-mongodb prefix avoids clashing with a collection slug. The admin UI uses the same URLs; use the exported backupPluginPublicApiPaths helper in client code.

Cron / external (Bearer CRON_SECRET)

GET  /api/backup-mongodb/cron/run        # enqueue a cron backup
GET  /api/backup-mongodb/cron/list     # list backups
POST /api/backup-mongodb/cron/restore  # body: { "url": "https://…" }
Authorization: Bearer <CRON_SECRET>

Admin (session cookie, or pollSecret for /task/:id where applicable)

| Method | Path | | -------------- | ----------------------------------------------- | | POST | /api/backup-mongodb/admin/manual | | POST | /api/backup-mongodb/admin/restore | | POST | /api/backup-mongodb/admin/backup-preview | | POST | /api/backup-mongodb/admin/restore-preview | | POST | /api/backup-mongodb/admin/delete | | GET | /api/backup-mongodb/admin/backup-download | | GET | /api/backup-mongodb/admin/task/:id | | GET / POST | /api/backup-mongodb/admin/settings | | POST | /api/backup-mongodb/admin/validate-blob-token |

Programmatic API

For scripts, hooks, and tests:

import {
  createBackup,
  listBackups,
  restoreBackup,
} from '@trieb.work/payload-plugin-backup-mongodb'

// Example: manual backup from a one-off script
await createBackup(payload, { cron: false, includeMedia: true })

// Example: restore from a URL, skipping `users`
await restoreBackup(payload, downloadUrl, ['users'], false)

// Example: list backup archives (token from backup-settings + env, same as create/restore)
const blobs = await listBackups(payload)

Blob storage model

Blob naming

backups/{type}---{dbName}---{hostname}---{collectionCount}-{timestampMs}.{json|tar.gz}

• type: cron or manual (and legacy-style labels where applicable).
• dbName / hostname: derived from your MongoDB URL and public server URL; URL-encoded in the name.
• collectionCount + timestampMs: sort key for listing; legacy blob names are still supported.

Public vs private stores

A validation step probes the bucket and records whether the store behaves as public or private. New uploads use the right access mode. Restore and preview flows handle both.

Overriding the backup store

To keep backups in a different Vercel Blob project than media (when BACKUP_STORAGE=vercel-blob), open Backup settings in the admin, paste a dedicated BLOB_READ_WRITE_TOKEN, validate, and optionally migrate existing backups/* objects to the new store before switching. For S3, the target is controlled entirely by environment variables.

Removed demo seed API (intentional)

Earlier releases exposed an optional demo seed route (seedDemoDumpUrl, /backup-mongodb/admin/seed, and the restoreSeedMedia export). That was removed on purpose: a backup plugin should not ship a public “seed my database” API. Use your own migration/seed tooling instead.

Running the tests

pnpm test:int

E2E (Playwright)

End-to-end tests live in tests/e2e/ and target the dev/ Next + Payload app. Locally, start Mongo (or rely on the in-memory replica set when DATABASE_URL / MONGODB_URI are unset), then either run pnpm dev and pnpm test:e2e in another shell (Playwright reuses the server when not in CI), or run only pnpm test:e2e so Playwright starts pnpm dev for you.

CI (.github/workflows/e2e.yml, same pattern as the reference e2e.yml in executive-search: MongoDB 7 service, pnpm run build then pnpm run build:dev, then Playwright against next start). Optional secret BLOB_READ_WRITE_TOKEN for fuller blob behaviour.

Optional: deploy dev/ to Vercel

.github/workflows/deploy-dev-vercel.yml runs when dev/ (or related paths) change on main, or via workflow_dispatch, only if VERCEL_TOKEN, VERCEL_ORG_ID, and VERCEL_PROJECT_ID are set. Configure the Vercel project Root Directory to dev (dev/vercel.json wires install/build from the repo root).

The repo includes a dev/ Payload + Next app (MongoDB Memory Server when no URI is set): pnpm dev → http://localhost:3000/admin (login in dev/helpers/credentials.ts). In unit tests, external services like @vercel/blob and bson are often mocked with vi.mock().

Publishing (npm)

Versioning uses Changesets: add a file with pnpm changeset, open a PR to main, and merge. The Release workflow opens a “version packages” PR or runs pnpm run release (build + changeset publish) when the set of changesets is ready. PRs need a new .changeset/*.md unless you add the no-changeset label (e.g. docs-only).

Roadmap / ideas

• Multipart / very large backup uploads (Vercel Blob supports large objects; may need to switch past single-part limits). (S3 uploads already use multipart.)
• Additional storage adapters (filesystem, etc.). (AWS S3 and S3-compatible stores such as R2/MinIO are supported — see Choosing a backup target.)
• Scheduler-agnostic display when not using Vercel (vercel.json is currently used for the schedule summary where available).
• Streaming restore for very large databases.
• Configurable backups/ prefix or bucket layout.
• add support for tenant plugin and partial backups per tenant
