BorgBackup vs Jaeger: at a glance
What is BorgBackup?
Borg 2.0 beta 25 breaks repositories to swap its hash and repository format.
BorgBackup's 2.0 beta line is still making breaking format changes. Beta 25 requires new repositories: it moves store object names to blake3, replaces several repository objects with an ini-style config, removes the none-sha256 and none-blake3 modes in favor of authenticated ones, and protects lock, index and cache objects with the repository key. The stable 1.4 line remains the production track.
What is Jaeger?
Jaeger's query service learns to search individual spans, not just whole traces.
Jaeger 2.21 and 2.22 extend the 2.x storage and query rework. ClickHouse storage moved to a stable feature gate in 2.21, and the release removed v1 HTTP endpoints the UI no longer calls. In 2.22 the query service gains FindSpans with RFC 0014 pagination, Elasticsearch span search, and structured filters promoted to beta, while native Elasticsearch trace summaries go stable.

Borg 2.0 beta 25 breaks repositories to swap its hash and repository format.
◆ Current state
BorgBackup's 2.0 beta line is still making breaking format changes. Beta 25 requires new repositories: it moves store object names to blake3, replaces several repository objects with an ini-style config, removes the none-sha256 and none-blake3 modes in favor of authenticated ones, and protects lock, index and cache objects with the repository key. The stable 1.4 line remains the production track.
◆ Where it's heading
Twenty-five betas in, the format is not settled, but this beta is decisive: it removes old modes and object types, which narrows what 2.0 has to support. Treating lock and cache objects as keyed data also extends the security model beyond archive contents.
◆ Prediction
Further betas are likely to keep requiring new repositories until the format freezes, so a release candidate should not be assumed soon. The 1.4 line stays the safe choice until then.
Jaeger
2.5INFRA · APIS
Jaeger's query service learns to search individual spans, not just whole traces.
◆ Current state
Jaeger 2.21 and 2.22 extend the 2.x storage and query rework. ClickHouse storage moved to a stable feature gate in 2.21, and the release removed v1 HTTP endpoints the UI no longer calls. In 2.22 the query service gains FindSpans with RFC 0014 pagination, Elasticsearch span search, and structured filters promoted to beta, while native Elasticsearch trace summaries go stable.
◆ Where it's heading
The earlier trace-summaries work made search cheaper; span search changes what can be asked. Pagination and structured filters give both the UI and MCP clients a way to query without pulling whole traces. MCP keeps getting practical limits and input checks, and search_traces no longer needs a service name on backends that declare support for that.
◆ Prediction
Expect span search to spread beyond Elasticsearch and memory storage, and structured filters to move from beta to stable as other gates have. Further removal of v1 surface is likely, since 2.21 already started it.
