RSS Sync

What is it?

Sonarr relies on RSS feeds to automate grabbing of releases as they are posted, for both newly aired episodes as well as previously aired releases being released or re-released. The RSS feed is the latest releases from a site, typically between 50 and 100 releases, though some sites provide more and some less. The RSS feed is comprised of all releases recently available, including releases for series you do not follow, if you look at debug logs you will see these releases being processed, which is completely normal.

The interval

Sonarr enforces a minimum of 10 minutes on the RSS Sync interval and a maximum of 2 hours. 15 minutes is the minimum recommended by most indexers, though some do allow lower intervals and 2 hours ensures Sonarr is checking frequently enough to not miss a release (even though it can page through the RSS feed on many indexers to help with that). Some indexers allow clients to perform an RSS sync more frequently than 10 minutes, in those scenarios we recommend using Sonarr's Release-Push API endpoint along with an IRC announce channel to push releases to Sonarr for processing which can happen in near real time and with less overhead on the indexer and Sonarr as Sonarr doesn't need to request the RSS feed too frequently and process the same releases over and over.

Sonarr has been offline

If Sonarr has been offline for an extended period of time, Sonarr will attempt to page back to find the last release it processed in an attempt to avoid missing a release. As long as your indexer supports paging and it hasn't been too long Sonarr will be able to process the releases it would have missed and avoid you needing to perform a search for the missed episodes.
