Duplicati vs Skipper: at a glance
What is Duplicati?
Duplicati turns Hyper-V and MSSQL backups into restorable, named sources.
Duplicati ships a canary roughly weekly and patched its 2.4 stable line on October 7. The 2.4.0.1 stable release focuses on restore reliability, abort handling and security hardening, and adds a reduced reporting mode that strips text and file names from anything leaving the machine. The October 11 canary makes Hyper-V machines and MSSQL databases first-class sources that can be restored to their original location.
What is Skipper?
Skipper patches a cache() filter security advisory amid routine maintenance tags.
Skipper tags a release for nearly every merge. v0.28.37 fixes security advisory GHSA-9hwf-c47m-j4pg in the cache() filter, and v0.28.38 removes a direct syscall dependency. Before that came test-certificate consolidation and five dependency builds. The last proxy changes, about ten days ago, were a fade-in path that stops copying endpoints per request and a fix for stale-while-revalidate refresh.

Duplicati
5.0INFRA · APIS
Duplicati turns Hyper-V and MSSQL backups into restorable, named sources.
◆ Current state
Duplicati ships a canary roughly weekly and patched its 2.4 stable line on October 7. The 2.4.0.1 stable release focuses on restore reliability, abort handling and security hardening, and adds a reduced reporting mode that strips text and file names from anything leaving the machine. The October 11 canary makes Hyper-V machines and MSSQL databases first-class sources that can be restored to their original location.
◆ Where it's heading
Canaries are moving Duplicati from file-level backup toward workload-aware backup for Windows servers, while stable releases harden restore and privacy. Restore correctness is the common thread, with restore-test commands, error reporting and link handling all fixed in the last month.
◆ Prediction
Expect the Hyper-V and MSSQL providers and restore-test command to reach a 2.4.x stable release after a few more canaries.
Skipper
6.3INFRA · APIS
Skipper patches a cache() filter security advisory amid routine maintenance tags.
◆ Current state
Skipper tags a release for nearly every merge. v0.28.37 fixes security advisory GHSA-9hwf-c47m-j4pg in the cache() filter, and v0.28.38 removes a direct syscall dependency. Before that came test-certificate consolidation and five dependency builds. The last proxy changes, about ten days ago, were a fade-in path that stops copying endpoints per request and a fix for stale-while-revalidate refresh.
◆ Where it's heading
Skipper keeps taking on edge responsibilities, identity via token exchange and response caching, while tightening the hot path. The new cache() filter is now drawing security research, a sign it's getting real use. The certificate refactor points to more TLS work, possibly between Skipper instances.
◆ Prediction
Expect a TLS-related feature to build on the unified certificate test setup, plus further cache-filter fixes as it matures. Otherwise, more Dependabot tags.
