Arq backs up your files using strong, end-to-end encryption so that your data can only be read by you. Arq uses filesystem snapshot technology to create perfect, point-in-time backups of your files, even if your files are changing during the backup process. Arq Backup integrates with many different cloud providers, so if you have a cloud account with some extra space available, you can use it for encrypted, versioned backups of your important files.
