The problem
Friday afternoons are for winding down, not panicking because a USB hard drive has stopped working.
A financial advisor in Worcester was backing up his most important client files the way most sole traders do: copying them to an external USB drive on his desk. It''s simple, it''s cheap, and it works — right up until the drive fails or the office it lives in floods, is burgled, or catches fire. The whole point of backups is that they exist somewhere the disaster doesn''t reach, and a drive sitting six inches from the machine it''s backing up isn''t that place.
He wanted an automated, off-site solution. His preference was Google Drive — he already used it, understood it, and could get to files from his phone. Our recommendation was Azure Blob Storage: purpose-built for backup, encrypted at rest, versioned, and not designed around a consumer sync model that ransomware can quietly poison.
What we built
A Python script running on his machine every day. It scans for files created or modified in the last seven days, compresses them, and uploads them to a private Azure Blob Storage container over an encrypted channel.
The seven-day window is deliberate. It''s not "only back up yesterday''s changes" — if he copies files across from his laptop or from a client meeting and the file''s modification date is a few days old, they still land in the next run. The daily cadence means missing one run doesn''t lose anything.
Azure Blob was chosen over Google Drive for three reasons that matter to a professional handling client financial data:
- Encrypted at rest by default, with keys the client controls
- Versioning — old copies aren''t overwritten when a new upload comes in, so a ransomware-encrypted file syncing up doesn''t destroy the last good version
- No consumer sync client — the backup destination isn''t a folder on his desktop that malware can find and delete
The result
The Python script runs quietly every day. He doesn''t remember it''s there. He doesn''t do anything on Fridays that he wouldn''t do on any other day. And if the office USB drive dies again — or the laptop is stolen, or a client folder gets ransomwared — he has a clean, encrypted, off-site copy of everything from the last week onwards.
For a sole trader, backup isn''t about surviving a natural disaster. It''s about surviving the small, boring, ordinary failures that happen without warning on a Friday afternoon. This is the plumbing that means one of those doesn''t turn into a client-losing weekend.
