With this extension, you can store your backups in S3 cloud storage.

Now you will never be short of disk space and your backups will be safe and sound in an S3-compatible storage of your choice. Store your backups on Amazon S3, DigitalOcean Spaces, Minio, OpenStack, and other services. Plesk administrators, customers, and resellers can use Amazon S3 Backup with access to all features available for regular server backups:

Features:

• Create manual or scheduled backups.
• Restore entire backups or only particular objects (domain configuration, databases, mail, and virtual host content).

Premium features (require purchasing Backup to Cloud Pro, which unlocks these features for all supported cloud storages):
