Duplicati vs SuperDuper!

Duplicati is backup software for Windows, macOS and Linux, covering computers and servers. It can back up desktops, laptops, local servers, NAS devices, Microsoft 365, Google Workspace and S3 buckets. Destinations include S3, WebDAV, SFTP and local hardware; cloud data can also be copied to an on-prem SAN or private S3 cluster. Data is encrypted locally with AES-256 before transfer, and only changed blocks are sent. Retention settings can remove older backups or keep a chosen number. Administrators can distribute backup configurations to clients, delegate local management to regional IT staff and isolate clients in sub-organizations. One subscription supports unlimited clients and endpoints. The free plan provides an insights dashboard, monitoring for up to two machines and access to the last 200 backups. Pro adds alerts, AI analysis, remote management, retention, storage and priority support. Enterprise adds organization management, configuration assistance, SSO with MFA, agent deployment and credential management. Pro is $2/mo billed annually; Enterprise is $3/mo billed yearly and requires at least 10 machines.

SuperDuper! makes backup copies of Mac drives, folders and files, with mixed backup and restore modes. It can create bootable copies on supported configurations, although a copy can still be restored when it is not bootable. Copy jobs are described through plain-English sentences. Smart Update copies new or changed files and removes items no longer on the source, while scheduled copies can run with the app closed or when nobody is logged in. Destinations include SMB, AFP and NFS network shares, and the app can connect to a share when a copy begins. macOS Shortcuts can run before or after a copy, or when one fails. SuperDuper! 4 is a native app for macOS 14 or later on Apple silicon or Intel, not an iPhone or iPad app. Unregistered use has no time limit and supports Erase, then copy backups; registration enables Smart Update, scheduling and network destinations. The paid license is listed at $43.95 a month, billed not a subscription.
