Just connect Arq to your own Google Drive account, Amazon Web Services account, SFTP server, Greenqloud account, DreamObjects account, or any S3-compatible server. Everything is encrypted before transfer, so your files are safe and secure. Arq backs up your files automatically, every hour. If you accidentally delete a file, you can go back in time and restore the file from your cloud backups. Back up external hard drives, NAS files, whatever you want. Arq has no limits.
