Automate recurring file backup to a central Drive

Regularly copy or back up user files to a central Shared Drive for compliance, disaster recovery, or offboarding, using a delegated service account.

The problem

Critical files are often scattered across user Drives, making compliance and disaster recovery dependent on each user's behaviour. Manual backup is inconsistent and unreliable, especially when staff leave or permissions change unexpectedly.

How it works

  1. Grant the service account domain-wide delegation with drive scope.
  2. Impersonate each user in turn to list and read their files and folders.
  3. Copy or move required files to a designated folder or Shared Drive under a service account-controlled identity.
  4. Log each operation, including skipped or failed files, for traceability and audit.
  5. Schedule the backup job to run at the required frequency (e.g., daily or weekly).

What changes

All critical documents are centrally available, even if a user is offboarded or their account is suspended, and backup coverage is auditable.

The trap in this one. Drive API 'copy' operations do not preserve sharing permissions or folder hierarchy by default; nested folders require recursive logic, and files with identical names in the same folder may overwrite each other or fail with a 409 error. Silent rate limiting can cause partial backups with no error at the job level—always check for per-file errors and implement exponential backoff, or you will discover missing files only when you need the backup.

Questions people ask

Can I use this to back up Shared Drives?

Not directly. Service accounts require explicit membership in each Shared Drive, and impersonation only covers user My Drives unless additional setup is done.

How do I handle large files or folders?

The Drive API paginates lists and may time out on large folders. Always implement paging and retries, and monitor for partial results.

Want this built?

This is a pattern we run in production. We will set up the delegation and build this on top of it — $500 per hour, most of it working the same day.
