How to migrate Azure Blob Storage to BucketPilot Cloud

Move a container from Azure Blob Storage to a BucketPilot Cloud bucket with a re-runnable, incremental job that resumes on its own — one-time or on a schedule.

Azure Blob Storage to BucketPilot Cloud, without a script

Moving from Azure Blob Storage to BucketPilot Cloud usually means a script somebody wrote once and a weekend of watching it. This job replaces the script: it copies everything, resumes if interrupted, and can be run again right before the switch to catch what changed.

Before you start

This job runs on the Business plan (Cloudflare R2 and Google Cloud Storage buckets, Azure sources and server destinations are Business features). Every account starts with a 14-day trial of Pro; see plans.

Step by step

  1. 1.Connect the source. Under Credentials, add the storage account's connection string (or a SAS with read and list rights). The container is chosen on the job.
  2. 2.Connect the destination. Nothing to connect. Under Buckets & Servers → Create Bucket, choose BucketPilot Cloud, pick a region (US, Europe or Asia Pacific) and a name, and the bucket exists in a minute — inside your workspace, with no keys to keep.
  3. 3.Open Backups & Migrations and press Create. Choose Azure Blob Storage as the source and A bucket as the destination, then Continue.

  1. 1.Pick the Azure credential and type the container, and a folder inside it if you want only part of it.
  2. 2.Pick the destination bucket and, if you like, a folder inside it where the files land.
  3. 3.Leave the schedule on manual for a one-time move, or set one if the source keeps receiving files and you want them to follow. Choose how many files copy in parallel (threads); eight is a good default for a busy server.

  1. 1.Press Create Job, then Run now. The first run copies everything; every run after it copies only what changed.

What happens on each run

Every run is incremental: a file is copied only if its size or timestamp differs from the copy, so a nightly run of a large source moves only the day's changes and finishes in minutes.

When both ends are on the same provider the copy happens server-side and the bytes never leave that provider; between providers, BucketPilot streams each file through, without keeping it.

You can watch it: live progress on the job, a per-file log, and an email when a run finishes or needs attention. Transient errors retry with backoff; a run that fails outright is reported, never silently skipped.

BucketPilot Cloud keeps every version of a file when versioning is on, and BucketPilot turns it on for a bucket it creates for a backup. A file overwritten or deleted by mistake at the source is still there in the copy, one click from restored.

What it costs

Getting files back

Every job has a Restore button: it copies from the destination back to the source, only what is missing there, never overwriting a newer file and never deleting anything. A backup you cannot restore from is not a backup, so this is part of the job, not a separate product.

Questions

Can I keep the source in use during the move?
Yes. Run the job once to copy everything, keep working, then run it again just before you switch over: the second run copies only what changed since the first.
What will it cost?
Microsoft charges for data leaving Azure after the first 100 GB a month. BucketPilot Cloud is billed per GB-month on your BucketPilot invoice; every file counts as at least 4 KiB. BucketPilot charges by plan, never per GB copied.
What about very large files?
Objects are copied in parts and a run resumes where it stopped. Single objects up to 5 GB copy as one object; larger ones are copied part by part by the provider.
Does BucketPilot keep my files?
No. Your files are copied from your source to your destination and are not stored by BucketPilot. We keep metadata — names, sizes, timestamps — to run the job and to make the copy searchable. Credentials are encrypted at rest.
