Yes—you can use Vultr Block Storage to hold video files for a continuous YouTube stream, but storage alone does not create or keep a broadcast live. A Vultr Compute instance must mount the volume, read the files, encode them with streaming software such as OBS, and send the feed to YouTube. You must also design and verify the playlist loop, process restart, and recovery behavior; Vultr’s published setup guide does not establish a complete unattended 24/7 design or verify YouTube’s current rules for continuous streams.
How the setup fits together
Think of this as three separate jobs: Block Storage holds the media; a Compute instance reads and encodes it; OBS sends the live feed to YouTube using your stream key. Vultr documents attaching Block Storage to a Cloud Compute instance in the same region, and its Ubuntu streaming guide describes an OBS-to-YouTube workflow. Neither component by itself makes a reliable 24/7 service.
- Storage: Create or use a Vultr Block Storage volume in the same region as the Compute instance. Vultr does not support cross-region attachment; for another region, replicate or synchronize the media to a volume there.
- Server: Attach the volume to the Compute instance. Vultr’s CLI documents a
--liveattach option that does not restart the instance. See Vultr’s Block Storage documentation for attachment details. - Streaming process: Mount the volume in Ubuntu, configure OBS and its media sources, then connect OBS to the YouTube Live stream using the stream key.
- Operations: Separately configure how media advances or loops, how the encoder starts after reboot, and how you detect and recover from encoder, server, or network failures. These behaviors are not established by the storage attachment itself.
Choose the server and storage for the workload
Vultr’s example server is a starting point, not a universal minimum
Vultr’s streaming guide, updated 1 April 2025, lists a server with at least 2 vCPUs, 4 GB RAM, 80 GB storage, and 3 TB bandwidth as prerequisites. It suggests 720p for a server with at least two vCPUs and advises monitoring CPU and bandwidth. These are the vendor’s recipe, not universal YouTube requirements or a guarantee that the configuration can encode every resolution, frame rate, or workload. Encoding settings, concurrent processes, audio/video filters, and available network capacity all matter. See Vultr’s OBS streaming guide.
Plan for the Compute instance’s own boot and working storage as well as the attached media volume. The media volume does not replace CPU, memory, or outbound bandwidth, and it does not provide a backup or recovery plan by itself.

HDD Block or NVMe Block?
Vultr’s May 2026 benchmark page gives the following sustained figures. They are vendor-published targets and benchmark results, not independent testing or guaranteed performance on a particular instance. The separate December 2025 support page also cautions that listed performance is not a guaranteed minimum.
| Vultr volume type | Published sustained target | Practical reading |
|---|---|---|
| HDD Block | 500 IOPS; 100 MB/s | Assess with sequential-read tests using your actual file sizes, stream count, and cache behavior. |
| NVMe Block | 10,000 IOPS; 400 MB/s | Higher published targets; do not assume they are necessary for one stream without measuring the workload. |
For reading video files, sustained sequential throughput is usually a more useful question than headline IOPS alone. Actual results depend on request size, parallelism, queueing, caching, and the instance’s CPU and network resources. Vultr’s May 2026 benchmark explains its fio methodology, including block sizes from 4 KB through 4 MB and varying read/write mixes and queue-depth/job settings. In its tests, NVMe reached about 10,000 IOPS and 40 MiB/s at 4 KB blocks, and about 6,000 IOPS and 381 MiB/s at 64 KB. Treat these as results from Vultr’s stated test setup, not a prediction for your server. See Vultr’s Block Storage benchmark, its Block Storage performance expectations, and its performance optimization guidance.

- Compare the tiers against measured sequential reads under the stream workload you expect, not only their published targets.
- Check current pricing and regional availability at purchase; they can change, and no price is established here.
- Plan backups, redundancy, and recovery separately. An attached volume should not be treated as a backup.
Attach and mount the volume in Ubuntu
Mounting a new volume changes disks and filesystems. Vultr explicitly warns that its sample partitioning and formatting operations can destroy existing data. Confirm the device and its data state before running any destructive command; do not copy commands blindly onto a disk that may contain data you need.
- Attach the volume to the Compute instance in the same region, using Vultr’s control panel or documented CLI. If using the CLI, review the current
--liveoption and command syntax in the attachment guide. - Identify the device: on the server, run
lsblkand confirm which newly attached device corresponds to the volume. If anything is ambiguous, stop and verify in the Vultr panel before partitioning. - Partition and create a filesystem only if the volume is new or you have confirmed it can safely be reformatted. Follow Vultr’s current Linux mount guide for the exact commands appropriate to the device and filesystem.
- Create a mount point, then obtain the filesystem UUID. Vultr’s guide uses the UUID rather than a device name in the boot-time mount configuration so the mount can persist across reboots.
- Add the UUID-based entry to
/etc/fstabas described by Vultr, then reload systemd and mount the filesystem. Confirm that the expected filesystem is mounted at the intended directory before moving media files or configuring OBS. - Verify persistence: check the mount after a planned reboot before relying on the server for unattended streaming. A typo or stale UUID in
/etc/fstabcan prevent the media volume from mounting as expected.
Use the current steps in Vultr’s Linux Block Storage mount guide, updated 24 September 2026. Its instructions and examples are vendor documentation; the warning about destructive formatting applies even when following the guide exactly.

Configure OBS and send the video to YouTube
- Prepare YouTube Live: in YouTube Studio, create or select the live event and retrieve its stream key. Treat the key like a password: do not put it in a public script, log, screenshot, or repository. Use the current YouTube Studio interface and account requirements for your channel.
- Install and open OBS Studio on the Ubuntu Compute instance, following Vultr’s streaming guide. Add the media source or sources that read from the mounted volume, then confirm audio and video playback locally in OBS before starting the broadcast.
- Set output to match the source and target: choose a resolution and frame rate the server can encode consistently, then set a video bitrate within YouTube’s current recommendation for that format. Vultr’s guide published these bitrate ranges in 2025:
| Resolution and frame rate | Bitrate range published by Vultr in 2025 |
|---|---|
| 480p at 30 fps | 500–2,000 Kbps |
| 720p at 30 fps | 1,500–4,500 Kbps |
| 720p at 60 fps | 2,500–6,500 Kbps |
| 1080p at 30 fps | 3,000–6,500 Kbps |
| 1080p at 60 fps | 4,500–9,500 Kbps |
| 2160p at 30 fps | 13,000–34,000 Kbps |
| 2160p at 60 fps | 20,000–51,000 Kbps |
These are Vultr’s published figures, not a current YouTube specification. Check YouTube’s current encoding recommendations before choosing settings. Set the keyframe interval and audio parameters according to those current recommendations as well; the cited Vultr guide does not establish a current, complete set of YouTube encoder settings for every format.
- Configure the stream destination: enter YouTube’s server/ingest details and the correct stream key in OBS. Do not disclose the key; reset it in YouTube Studio if it is exposed.
- Enable reconnect behavior: Vultr’s 2025 guide suggests OBS automatic reconnect with a retry delay of three seconds or less and at least 1,000 retries in its example. This is a vendor suggestion, not a guarantee that a stream will recover from every failure.
- Start and verify: start streaming in OBS, then check the YouTube Live control room and the channel playback. Watch OBS dropped frames, server CPU, and network bandwidth while the stream runs. Vultr warns in its guide that CPU use above 90% may lead to dropped frames and buffering; treat that as its caution, not a universal threshold for all encoders.
Vultr’s guide covers a server-based OBS broadcast, but it does not specify every current OBS version, YouTube interface label, or account eligibility rule. Follow the current screens and requirements shown for your account.

Make a continuous stream genuinely unattended
Starting one OBS broadcast is not the same as operating a continuous playlist service. Before calling the system 24/7, decide how it behaves at each failure boundary and test those behaviors without relying on Block Storage to provide them.
- Playlist and looping: define how the chosen OBS media source or other playback process advances through files and repeats them. Verify what happens at the end of the list, with an unreadable file, or after a media directory changes. Vultr’s streaming guide does not document a complete indefinite playlist-loop design.
- Process restart: decide how OBS or the selected encoder starts after a server reboot and what should happen if it exits. Vultr’s guide does not provide a complete service-manager configuration for unattended restart.
- Connection recovery: test a dropped network connection and a stopped encoder, and confirm what YouTube and your process do when connectivity returns. OBS’s reconnect setting alone does not establish automatic recovery for all failure types.
- Monitoring and alerts: monitor server reachability, encoder state, CPU, disk reads, and outbound bandwidth. A process can remain running while the broadcast has stopped or is no longer sending useful video.
- YouTube rules and archives: verify YouTube’s current live-stream policies, account eligibility, copyright obligations, and any archive behavior relevant to your channel and content. The cited Vultr sources do not establish current 24/7 limits, archive duration, or policy compliance.
- Recovery copies: keep a separate copy of important media and configuration, including a secure way to restore the stream key. Block Storage attachment is not a backup or failover system.
Troubleshoot common failures
| Symptom | Likely area to check | Useful next step |
|---|---|---|
| Media directory is missing after boot | Volume attachment, filesystem UUID, or /etc/fstab entry |
Run lsblk, verify the mounted filesystem and UUID, and check the boot-time mount configuration against Vultr’s Linux guide before restarting OBS. |
| OBS cannot read a file | Mount path, file permissions, or file path in the source | Confirm the volume is mounted and the OBS process can read the exact file. Test playback before reconnecting the broadcast. |
| Playback stutters or frames drop | CPU, bitrate/encoder load, disk read pattern, or network capacity | Check OBS statistics and server CPU/bandwidth. Test sequential reads and reduce encoding demand or stream settings if the instance cannot sustain the chosen workload. |
| Stream disconnects and stays offline | Encoder process, network path, key/destination configuration, or reconnect handling | Check OBS logs and YouTube Live status, confirm the key and ingest configuration, then test reconnect behavior and process restart separately. |
| Stream stops at the end of a video or playlist | Playback source’s end-of-file or loop behavior | Configure and test the playlist loop explicitly; storage does not automatically replay files. |
| Volume cannot be attached | Region mismatch or attachment state | Confirm the volume and Compute instance are in the same region. For another region, copy or synchronize the media to a volume in that region. |
