Vercel's 30-Day Retention Change: Protect Your Client Handoff
Before handing off a Vercel app, agree on how long the client needs old deployments, verify the project's actual retention settings, and identify a usable rollback target. A Git commit is not a retained deployment, and neither is a database backup. Vercel's October 9, 2026 notice makes that distinction urgent: deletion of older deployments under the announced 30-day policy starts October 23 unless an affected team opts out beforehand.
For freelancers and small agencies, the useful deliverable is not a screenshot of a retention dropdown. It is a short recovery record that connects the client's support window to a deployment, its dependencies, and the person allowed to restore service.
What changes on October 23?
Vercel's notice for existing Pro teams, published October 9, says deployments older than 30 days will begin to be deleted on October 23 unless teams opt out in retention settings. Policies already set to 30 days or less stay unchanged. The notice also introduces Deployment Storage and Functions Storage billing for all Pro teams; the team's email provides its billing start date. Do not assume October 23 is every team's billing date.
A separate October 9 announcement for new Pro teams says their default is now 30 days, with longer retention available in settings. Both notices warn that deleted deployments are unavailable for rollback.
There is a documentation discrepancy worth recording. As checked on October 14, the general retention guide, last updated September 16, still lists longer Pro defaults and describes a recovery period for successfully built deployments marked for deletion. The newer announcements are more restrictive. Do not promise a client that recovery period or infer their effective policy from the old table. Check the actual project settings and team notice; ask Vercel support if their applicability is unclear.
Separate the three recovery assets
Use this distinction in the handoff discussion:
| Asset | Question it answers | Evidence to retain |
|---|---|---|
| Retained deployment | Can we route traffic to a previously built release? | Deployment ID, URL, production history, eligibility and last verification date |
| Rebuildable source | Can we produce a new build of the intended version? | Commit SHA, lockfile, runtime version, build settings and a successful controlled rebuild |
| Recoverable application data | Can we recover or reconcile records and uploaded files? | Separate backup/restore procedure, retention, owner and latest restore-test result |
The table is a suggested agency handoff format, not a claim that these checks have been performed for your app.
Vercel's production rollback guide explains that rollback redirects production to an existing deployment without rebuilding. That is different from checking out an old commit and building again. A rebuild can encounter a changed runtime, unavailable dependency or changed external service. For a current runtime-related example, see our Vercel Node.js 20 upgrade guide.
Keep the data-recovery procedure separate. Routing to old application code does not reverse a database migration or undo orders received after a release. Before considering an older build safe, check whether it still understands the current schema and external API contracts.
Inspect one client project before changing a team default
Start with a read-only inventory. Record the Vercel team and project, who owns them after handoff, the plan, the four retention categories, and the date checked. Include any project-specific override and the client approval or warranty period you are expected to support.
Vercel's storage optimization guide distinguishes two scopes:
- Project Settings → Security → Deployment Retention Policy changes that project only.
- Team Settings → Security & Privacy → Deployment Retention Policy sets the default for new projects. Selecting Apply this policy to all existing projects also replaces every existing project's policy.
For an agency hosting several clients, the second option is a cross-client change. Obtain the relevant approvals before using it. A request to review one client's handoff is not permission to shorten every client's history.
Check the age and status of the deployment you actually intend to keep. Retention is not an exact deletion timer: the general guide documents exceptions for production aliases, certain other aliases, active-branch previews and recent deployments. An old URL responding today therefore does not prove it will remain available through the client's support period. Document the current exception, if any, rather than silently depending on it.
Choose a support window, then assess storage
Ask the client when a regression is likely to be reported and who will investigate it. A monthly reporting workflow, for example, may not exercise its most important path during a short acceptance review. That is a planning scenario, not a universal recommendation to keep every deployment indefinitely.
Record separate decisions for production recovery, pre-production review, and failed-build investigation. Choose from the durations actually available in the project's settings. If the required window is longer than the proposed policy, obtain approval for an appropriate setting before the announced change rather than relying on eventual recovery.
The Deployment Storage documentation lists Pro prices of $0.10 per GB-month for each of two metrics: build/static output and Functions Storage. Function bundles are stored in their deployment regions. Vercel measures each project's daily maximum stored amount and aggregates usage across the billing period; allowances and contract terms may affect the actual charge.
Review both metrics on the team's Usage page, broken down by project. A count of deployments alone is not a cost estimate. Record the date range, measured usage, applicable allowance and billing start date before giving the client a budget figure. This article does not estimate your bill.
Prove the recovery path without touching live traffic
Use a non-production rehearsal with approved test data, or a scheduled production exercise with explicit authorization. Do not perform an unannounced live rollback merely to complete a checklist.
For the selected production rollback candidate, record:
- Its exact deployment ID and commit, and whether the authorized operator can see it as an eligible target.
- The important customer journeys that must work: sign-in, record reads and writes, uploads, and any relevant background processing.
- Changes since that release which may prevent reuse: migrations, rotated credentials, removed APIs or changed configuration.
- The result and time of the rehearsal, unresolved failures, and a fallback such as a reviewed forward fix.
Vercel's Instant Rollback documentation says the old build keeps its original environment-variable state; it does not acquire subsequent project-setting changes. Cron configuration also reverts. Deployments previously assigned a production domain are eligible; ordinary previews that never served production are not equivalent rollback targets.
The same guide notes that rollback disables automatic production-domain assignment. Include an authorized undo/promotion step in the recovery runbook so the next push is not mistakenly assumed to be live. Verify the public application and logs after any real recovery action.
These are documentation-based checks, not proof that every retained build remains compatible. For broader release evidence, pair the runbook with our pre-launch security checklist for AI-built apps.
Reduce waste without erasing useful evidence
If storage is high, investigate output size as well as retention. Vercel's optimization guidance recommends inspecting deployment Resources for large static files and Function bundles, and checking duplicate deployment triggers. Removing unnecessary packaged archives or unused dependencies can reduce future output without shortening the agreed recovery window.
Treat those edits as application changes: review them, test affected routes and Functions, and compare a new preview with a baseline. Excluding a required runtime file can break a function even when its build succeeds. Do not delete old releases, close client pull requests or remove aliases merely to make a usage graph smaller.
A handoff that survives the deadline
Before October 23, give the client one concise record containing the current policy, approved support window, retained target, rebuild evidence, separate data-recovery owner and any unresolved compatibility limits. Add who can authorize changes and the next review date.
The acceptance question is simple: “If this release fails next month, which recovery path have we actually verified?” A working homepage and an old Git tag are not enough to answer it.
