Backup streams

A backup feed for your YouTube stream

Keep a second feed running to YouTube. If the main feed drops, YouTube switches to the backup and returns when it recovers. Upstream also restarts interrupted streams automatically.

Start streaming Talk to our team

A copy of your stream

The backup copies your main stream's settings and re-syncs every minute.

YouTube switches feeds

YouTube takes over switching to the backup and back to the main feed.

One extra stream slot

A backup uses one stream slot for your main destination. The destination must support backup ingest.

A backup on standby

Send a 1:1 copy to YouTube's backup ingest. YouTube switches to it if the main feed drops, then switches back. Settings re-sync every minute. The backup uses one stream slot and covers the main destination.

Secure what's importantBackup streams are exact (1:1) replicas of your main stream. They are used to ensure your stream is always online, even if your main stream is down.

Each destination retries on its own

Each multistream destination retries 5 times on its own. The backup covers your main destination; it does not cover these extra outputs. Upstream emails you if a destination stays disconnected after its retries.

Key facts

Backup feeds, retries and alerts

The backup sends a second feed. Upstream also restarts the encoder and retries each destination independently. Here is what happens when a stream stops.

Mechanism What it does Scope or limit
Backup stream Sends a 1:1 copy; settings re-sync every minute Uses a stream slot; main destination only
YouTube backup ingest YouTube switches to the backup and back by itself Other platforms must support backup ingest
Encoder recovery Relaunches up to five times; stalled output gets a hard reload An ended YouTube event is recreated
Destination retries Retries each multistream connection up to five times Independent of the backup feed
Email alerts Reports stops, rejected keys, failed destinations and ended or replaced YouTube events Automatic recovery and backup streams do not include an SLA

Platform session limits still apply to a backup. Count your channels and check each platform's output settings before choosing stream slots.

Before you start

Before you add a backup

1

Check the destination

YouTube has backup ingest. On another platform, a backup only works if that platform supports it. See YouTube primary and backup RTMP .

2

Allow a slot for the backup

The main stream and its backup each use a stream slot. Extra multistream destinations have their own recovery: each retries up to 5 times.

3

Check your files and session limits

Review file checks and platform session limits. A backup does not remove those limits.

The value you get per dollar is amazing. Many features are available at no cost when other similar services charge for them or do not have them available at all.

FAQ

Questions about backup streams

It is YouTube's backup ingest address. Upstream sends the backup there, and YouTube switches between the main and backup feeds automatically.

Yes. The backup is a separate stream with its own slot. Count both the main stream and the backup when choosing your plan.

No. A backup covers the main destination only. Each extra multistream destination retries independently, up to 5 times.

The platform must support backup ingest. YouTube does, and it handles the switch to the backup and back to the main feed.

No. Upstream does not offer an SLA. Automatic recovery and backup streams are available.

Upstream relaunches the encoder up to 5 times, waiting 15, 30, 60 and 120 seconds between attempts. It recreates an ended YouTube event and hard-reloads stalled output. Each multistream destination retries 5 times on its own.

You get an email when a stream stops or a destination stays disconnected after its retries. An invalid or rejected key pauses the stream and sends an email. Upstream also emails you when a YouTube event ends or is replaced.

It sends to rtmp://b.rtmp.youtube.com/live2?backup=1. YouTube handles switching between feeds, and the backup settings re-sync every minute. Read the YouTube primary and backup RTMP guide, or see how playlists reach your destination with cloud playout.

No. Twitch restarts at 48 hours. Instagram multistreams stop at 3 hours 55 minutes; Facebook multistreams stop at 7 hours 55 minutes. Check platform limits when planning the schedule and preparing programme graphics.

Count a stream slot for the main feed and another for its backup. The backup covers the main destination only, which must support backup ingest. Check file checks and reencoding before building the playlist.
