 If you choose to use the sidecar to also upload data to object storage:
 
 * Must specify object storage (`--objstore.*` flags)
-* It only uploads uncompacted Prometheus blocks. For compacted blocks, see [Upload compacted blocks](./sidecar.md/#upload-compacted-blocks-experimental).
+* It only uploads uncompacted Prometheus blocks. For compacted blocks, see [Upload compacted blocks](./sidecar.md/#upload-compacted-blocks).
 * The `--storage.tsdb.min-block-duration` and `--storage.tsdb.max-block-duration` must be set to equal values to disable local compaction on order to use Thanos sidecar upload, otherwise leave local compaction on if sidecar just exposes StoreAPI and your retention is normal. The default of `2h` is recommended.
   Mentioned parameters set to equal values disable the internal Prometheus compaction, which is needed to avoid the uploaded data corruption when Thanos compactor does its job, this is critical for data consistency and should not be ignored if you plan to use Thanos compactor. Even though you set mentioned parameters equal, you might observe Prometheus internal metric `prometheus_tsdb_compactions_total` being incremented, don't be confused by that: Prometheus writes initial head block to filesytem via its internal compaction mechanism, but if you have followed recommendations - data won't be modified by Prometheus before the sidecar uploads it. Thanos sidecar will also check sanity of the flags set to Prometheus on the startup and log errors or warning if they have been configured improperly (#838).
 * The retention is recommended to not be lower than three times the min block duration, so 6 hours. This achieves resilience in the face of connectivity issues to the object storage since all local data will remain available within the Thanos cluster. If connectivity gets restored the backlog of blocks gets uploaded to the object storage.

 If you want to migrate from a pure Prometheus setup to Thanos and have to keep the historical data, you can use the flag `--shipper.upload-compacted`. This will also upload blocks that were compacted by Prometheus. Values greater than 1 in the `compaction.level` field of a Prometheus block’s `meta.json` file indicate level of compaction.
