Vykar Hosting Live In 5 Minutes

Deploy Vykar hosting and give your Vykar clients a private backup target on your own domain. xCloud runs the pinned Vykar 0.20.1 REST backup server as a single container, generates the access token, mounts a persistent repository volume and publishes the server over HTTPS in minutes — backup contents are encrypted on the client, so the server never holds your encryption key.

What is Vykar?

Vykar is an open-source backup tool written in Rust, driven by a YAML configuration file. It encrypts and deduplicates data on the client and can store repositories on a local filesystem, any S3-compatible provider, SFTP or a dedicated REST server.

This page hosts that REST server: a single token-protected endpoint your Vykar clients back up to. It is a backup target, not a web application — there is no login page and no dashboard.

From Sign-Up to a Live Backup Server In Just 3 Easy Steps

A Vykar server normally means a container, a long random token, a data volume, a domain and a certificate before the first backup. This is the same result without assembling any of it.

Step 01
Sign Up
Create your xCloud account and pick Vykar from the OneClick catalog. Choose your domain and target server — there are no extra fields to fill in.
Step 02
We Deploy It For You
One click. We bring up the official Vykar image, pinned by immutable digest, as a single container running the REST backup server, mount the vykar_repo volume at /repo, generate a 48-character access token, and publish it over HTTPS on your domain.
Step 03
Point Your Client At It
Copy the repository URL and access token from the protected installation credentials. In your Vykar client configuration set the repository url and access_token, then run vykar init and vykar backup.

Everything Vykar Does, On Your Own Server

The Vykar REST backup server runs in full here: a token-protected repository endpoint on your own domain, storing data on a volume you own.

A REST Backup Target
Vykar clients back up to the server over HTTPS using the repository URL and access token xCloud shows you after install.
Client-Side Encryption
Vykar encrypts with AES-256-GCM or ChaCha20-Poly1305 on the client, so the server holds neither the passphrase nor the key.
Deduplicated Backups
Vykar uses FastCDC content-defined chunking to deduplicate data, with LZ4 or Zstandard compression.
Append-Only Mode And Quotas
Add the --append-only or --quota flags through VYKAR_SERVER_ARGS to reject deletes and overwrites or cap the storage the server uses.
Concurrent Multi-Client Backups
Several machines can back up to the same repository at once; upstream serialises only the brief commit phase.
Token-Protected Access
Every request except the health probe needs the generated bearer token; requests with no token or a wrong one are rejected with 401.

What You Can Do With Vykar

A private target for encrypted backups
Point your servers and laptops at one HTTPS endpoint you control, with data encrypted on each client before it leaves the machine.
One repository for several machines
Multiple Vykar clients can back up to the same repository at the same time, so a small fleet can share one backup server.
Backups a compromised client cannot erase
Turn on the optional append-only flag so the server rejects deletes and overwrites; the trade-off is that client-side prune and compact are blocked too.
Capped backup storage
Set a quota with the --quota server flag to limit how much space the repository can use on the server.

Vykar vs Alternatives

BorgBackup: Named in Vykar's README as an inspiration. Vykar uses its own on-disk format and is not compatible with Borg repositories.
Restic: Also named as an inspiration. Vykar's repositories are not compatible with Restic's, so existing Restic data cannot be pointed at a Vykar server.
Rustic: Another named inspiration, and likewise a separate on-disk format from Vykar's.
Duplicati: Runs scheduled encrypted, deduplicated backups from a browser dashboard. Vykar is configured through a YAML file and its server has no web interface.

Hear what people are saying about us

See why agencies, developers, startups, and growing businesses choose xCloud to power their projects.

xCloud works really well, I am surprised by its performance being this the release version, I have tried many paid platforms such as runcloud, cloudpages or serveravatar, as well as free platforms such as CyberPanel, CloudPanel or Hestia Control Panel and direct competitors such as SpinupWP and FlyWP. Of all those that I have tried, the platform that works best for WordPress is SpinupWP and I believe that xCloud can reach and surpass that development, its roadmap is promising. Congratulations to the xCloud team, I hope they become the leading platform in the segment, it has all the potential to achieve it!

Brian Geovanny

I've been with runcloud for the last 3 years. However, after trying xcloud for the last month, I'm switching over. They are on a roll with their setup.

Kevin Pineda

I'm moving my servers to xCloud, a cloud control panel by M Asif Rahman and the WPDeveloper team. Their roadmap looks interesting and no, there are no team mates nor API limits with xCloud! #xCloud #wordpress #hosting

How Cloud Nine Web Elevated Client Experience While Streamlining Hosting Operations using xCloud

Ed Ellingham

xCloud is like having an expert server team on call — without the big agency costs. It's given me back my time and given my clients peace of mind. Highly recommended for freelancers and small teams who want reliable performance and security.

Dumitru Butucel

xCloud isn't just a solution. It's like one of that friend who got your back when you screw things up pretty bad.

Waqar Ahmed

Trust me when I say, once people explore the potential of xCloud they gonna switch from other panels, just keep delivering the best tech, lots of love for the team 😍😍

Rahul Singh

So far my experience has been smooth like silk. I didn't imagine that configuring and managing a VPS would be so easy. As of today, I have deployed 8 sites. The support is good, and they treat users with respect, even if they ask stupid questions (myself included). For the future, I hope for greater flexibility in scheduled backups and more comprehensive and consistent documentation. I'm sure that within a few months, xCloud will become the leader in its segment. This community is amazing, and the Staff here is super helpful.

Massimo Villa

Came from cloudways then to runcloud then to xcloud. Looks like I'm staying here.

Gerson El

I've recently taken all of my Vultr-hosted sites and gotten rid of cPanel for them to substitute it with xCloud. I have to say, I'm really impressed with xCloud so far! The interface is definitely the standout feature for me.

Tony Lewis

I came from Cloudways and won't go back. Highly impressed with xCloud. Glad I gave them a chance.

Jared McDowell

I like xCloud better than RunCloud, but one thing I'll point out is that some years ago RunCloud was hungry for business, the support was outstanding, and the community was active and helped each other. Maybe it was sold, there was a change in management, or they stopped being hungry, but the quality of the RunCloud offering declined and it hasn't been moving forward quickly. My point is that currently the xCloud team has the edge and it is theirs to keep or lose

How Kevin Heinrichs Cut Hosting Costs by 84% While Running WooCommerce & Node.js Sites Efficiently

Kevin Heinrichs

I had 150 sites on cloudways and am in the process of moving them to xcloud. Much faster and better priced.

Dan Spinoza

Dear xCloud Team, I have been using xCloud for some time now and am genuinely impressed with its capabilities and the flexibility it offers by allowing users to bring their own VPS for management. It's a fantastic service, and my experience so far has been very positive. Successful migrated 5 sites on a single server. Xcloud migration tool worked great. There were few hiccups with security plugin like MalCare but disabling the plugin prior to migration worked just fine.

Rahil Maknojia

Came from runcloud. Tried xcloud and never came back.

xCloud gave me what no other hosting platform could: the flexibility of a VPS with the convenience of managed WordPress. As a solo founder running an entire business on one server, that combination is an important unfair advantage.

Frequently Asked Questions

Feel free to contact us with any questions or concerns you may have.

Is this a web app?

No. It is the Vykar REST backup server: a token-protected endpoint that Vykar clients back up to. There is no login page and no web interface.

How do I connect a client?

Set the repository url in your Vykar client configuration to your HTTPS address and access_token to the generated token, then run vykar init and vykar backup. The URL and token are in the protected installation credentials.

How does authentication work?

There are no accounts. xCloud generates a 48-character access token and every request except the health probe must carry it. In verification, requests with no token or a wrong token were rejected with 401.

Can the server read my backups?

Backup contents are encrypted on the client and the server does not hold the key, but it can see repository structure, object sizes and timestamps.

How do I rotate the access token?

Change VYKAR_TOKEN in the environment editor and redeploy, then update access_token in every client. Treat the token like a root password: anyone holding it can read, overwrite and delete the stored repositories.

Edit environment variables and redeploy

Why do I need to set max_pack_size?

Behind the Cloudflare proxy a single request is limited to about 100 MB, which is smaller than the client's default pack size. Set max_pack_size to 64 MiB (67108864) or lower on each repository, or large backups can fail.

Can I make backups append-only?

Yes. Add the optional --append-only flag in VYKAR_SERVER_ARGS. It also blocks client-side prune and compact. The --quota flag goes in the same variable if you want to cap storage.

What should I back up?

Platform backups are not available for this app, so copy the vykar_repo volume off the server regularly. Also keep each client's repository passphrase: without it the data is unreadable.

What survives a restart?

Data on the vykar_repo volume. In QA a snapshot was still listed and the restored file was identical after a restart, because it is a persistent named volume.

Is Vykar ready to be my only backup tool?

Upstream's README says not to use Vykar for production backups yet, and to test it alongside other backup tools. Treat this server accordingly.

Does xCloud automatically update Vykar?

No. The template pins Vykar 0.20.1 by immutable digest; new installations use the pinned release, existing sites are not automatically upgraded. Read the upstream release notes, then bump the readable tag and digest together on your own schedule.

What are the server requirements, and why does this page sell 6 GB?

The template's baseline asks for 1 CPU core, 256 MB of RAM and 20 GB of disk; measured use in QA was about 11 MiB idle and about 21 MiB after a backup round-trip. This page sells the 6 GB tier as the entry rung, whose 100 GB NVMe SSD leaves room for stored repositories to grow.

Is xCloud officially partnered with Vykar?

No. No official partnership or endorsement between xCloud and the Vykar project has been verified. This is a deployment and server-management option for the open-source Vykar project.

Can I cancel anytime?

Yes. There is no lock-in — cancel any time. Hosting is billed monthly and charged for what you actually use, so when you delete the server the unused balance is refunded to your account, less up to 10% in payment-processing fees.
