Migrating Google Cloud Storage to AnubizHost Offshore
GCS is fast, multi-region, and US-jurisdictional. For workloads that need offshore data residency or want to escape GCP egress pricing, this guide walks through mirroring GCS buckets to MinIO on an AnubizHost offshore storage VPS with rclone.

Plan GCS Egress and Authentication
GCS egress to internet is ~$0.12/GB outside North America. Budget ~$120 per TB for migration egress. Use a service account JSON key for read-only GCS access on the AnubizHost target - never use user credentials for bulk operations.
List buckets and sizes with gsutil du -s gs://bucket-name. Note storage classes (Standard, Nearline, Coldline, Archive) - retrieval cost varies, especially for Archive which has retrieval fees.
Set Up MinIO Target
On an AnubizHost storage VPS, install MinIO as described in our S3 migration guide. Create buckets matching GCS names with mc mb local/mybucket.
If you need multi-region semantics, deploy MinIO across two AnubizHost VPS instances in Romania and Iceland with replication enabled - this gives you cross-jurisdiction redundancy that's actually stronger than GCS multi-region in a single country.
Mirror with rclone
Configure rclone with a Google Cloud Storage remote (backend type: google cloud storage, auth via service account JSON) and MinIO remote (backend type: s3, custom endpoint). Sync:
rclone sync gcs:mybucket minio:mybucket \
--transfers=16 --checkers=32 \
--gcs-bucket-policy-only \
--progress --log-file=/var/log/rclone.logrclone handles GCS pagination, retries, and parallel transfers. For petabyte-scale workloads, look at AWS Snowball-equivalent physical transfer - GCP Transfer Appliance exists but is rarely cost-effective unless you're moving to GCP.
Verify and Cut Over Applications
Run rclone check gcs:mybucket minio:mybucket to confirm parity. Update application code: GCS SDK calls (storage.googleapis.com) become S3 SDK calls (storage.yourdomain.com). Most languages have an S3-compatible client (boto3 in Python, aws-sdk in Node.js).
For signed URLs: GCS V4 signed URLs are not portable. Generate new pre-signed URLs from MinIO with mc share download for any URLs that need to remain valid.
MinIO Operational Advantages
MinIO is open source, self-hosted on AnubizHost offshore infrastructure, and includes versioning, lifecycle rules, replication, and IAM policies. Per-GB storage cost is fixed (no class transitions), and egress is unmetered within your VPS bandwidth allowance. Related reading: offshore storage, S3 migration, Spaces migration.
