MB SQL Backup
A personal tool by Marcelo Blanc.
MB SQL Backup is a Windows service that backs up Microsoft SQL Server databases on a schedule (full, differential and transaction log backups), checks and encrypts each backup, and copies it to storage chosen by whoever runs it: a folder, an FTP or SFTP server, S3-compatible storage, Azure Blob Storage, Google Drive or OneDrive. It deletes old backups by a retention rule and can restore them.
Google Drive
When its owner connects a Google account, the service uploads backup files to a folder in that account's Google Drive, lists and deletes the old backups it created there, and downloads them to restore. It asks only for access to the files it creates itself and for the account's email address, which it shows so the owner knows which account is connected. It cannot see any other file in the Drive.
