Google Cloud Storage migrations,
without scripts.

Mover is the data-migration tool from Files.com. One-time moves between 20+ providers — no subscriptions, no surprises, no scripts.

Migrate data to or from Google Cloud Storage with Mover — fast, simple, and at a fraction of what other migration tools charge.

What we've watched

Where GCS migrations come from. Where they go.

Inbound: somebody picked BigQuery or Vertex AI and pulled the data over to sit next to it. Outbound: the egress bill caught up. Hundreds of GCS migrations later, those two patterns cover most of them.

Into GCS

Standardizing on Google Cloud for analytics and AI

Teams building on BigQuery, Vertex AI, Dataflow, or GKE pull data into GCS to keep it next to the analytics, ML, and compute layer they already use.

Multi-region durability without complexity

GCS Multi-Region and Dual-Region storage classes replicate data across geographies automatically. Customers with availability requirements often end up on GCS for the geography model.

Consolidating into one Google Workspace tenant

Organizations that already run on Google Workspace move file workloads into GCS to align identity, billing, and compliance with the tools their teams use every day.

Out of GCS

Cost arbitrage to Wasabi or Backblaze B2

GCS egress is the most expensive of the three hyperscalers — roughly $0.12/GB at the starting tier. Both Wasabi and Backblaze run a fraction of GCS Standard at rest and charge zero egress. For read-heavy workloads, the round-trip can pay for itself in months.

Multi-cloud rebalance to AWS or Azure

Moving primary storage to align with an AWS-first or Azure-first compute stack.

Cross-project or cross-region reorg

Project splits, region migrations, or compliance-driven moves between GCS buckets.

Common pairings

Pair GCS with any cloud.

GCS migrations rarely happen in isolation. These are the providers we pair with most often — one-click setup on either side, same dry-run flow, same audit trail.

Connection

How Mover connects.

Mover supports 2 standard Google authentication methods. Pick the one that matches how your team manages credentials.

01Method

Service account JSON key

Standard for accounts you control. Create a service account in Google Cloud, grant it Storage Object Admin (or narrower) on the buckets you're migrating, and paste the JSON key into Mover.

Scope:Mover uses the credential you provide and nothing more. Service account roles should be scoped to the specific buckets you're migrating, not the whole project.
02MethodRecommended

HMAC key

Useful when your existing tooling already uses GCS via its S3-compatible interoperability layer. Mover accepts HMAC access keys generated in the Google Cloud Console.

Scope:Mover uses the credential you provide and nothing more. Service account roles should be scoped to the specific buckets you're migrating, not the whole project.

Egress Savings

See your twelve-month savings.

Move from a paid-egress provider to one with free egress and your monthly invoice shrinks. Plug in your data size and how much you read from storage each month — the calculator does the rest, including the one-time Mover migration cost.

Start a Free Dry Run

Numbers use published standard-tier rates from each provider as of May 2026. Actual invoice varies by region, committed-use discounts, and your specific contract. Mover migration cost uses the cheapest combination of prepaid usage packs that covers the data size — packs stack, so a 2 TB migration is two 1 TB packs, not one 5 TB pack. The dry run prices the migration against your actual data and shows the exact one-time Mover cost before you commit.

Getting started

4 steps to Go.

From credential to first byte in four clicks. The dry-run is free, every time, and shows the exact cost before you commit a byte.

01

Connect GCS.

Paste a service account JSON key or an HMAC access key. Mover validates the credential and lists buckets it can see.

02

Choose source and destination buckets.

Apply filters and a date range if you want a partial migration.

03

Run a dry-run.

Mover walks the source bucket, counts files, sizes the transfer, and produces an exact cost estimate — Mover fees + GCS egress.

04

Launch.

Live progress, automatic retries on transient failures. Pause, resume, or cancel at any time.

Common Questions

Frequently asked.

Most teams launch their first migration in under 15 minutes. The dry run is free, every time.

A service account JSON key, or an HMAC key generated in the Google Cloud Console. Service account keys are the standard path; HMAC keys are useful when your existing tooling already uses GCS via the S3-compatible interoperability layer.
