Cloudron Forum

Hello @james ,

Thanks for the response.

My question is more about architecture and best practices for running Cloudron as a more serious mail server setup.

Until now my usage was mostly hobby-level, with small mailboxes. Now I need to host around 60 accounts totaling ~1TB, so I'm trying to design the setup properly before deploying it.

What I'm trying to understand is mainly:

1. Storage layout

I understand I could simply expand the primary disk of the VM. That is straightforward in Proxmox.

However, from a system design perspective, I was wondering if it would be better to:

• keep the system disk small (OS + Cloudron core)
• attach a separate disk dedicated to mail storage

For example mounting something like:

/home/yellowtent/boxdata/mail

on a dedicated volume.

The idea behind this would be:

• better separation between system and mail data
• easier capacity management
• possibility of using a filesystem with compression (e.g. zstd) to maximize storage efficiency
• simpler disk replacement or migration in the future

But at the same time I don't want to diverge from the recommended Cloudron layout, because I would like to keep the installation as "standard" as possible in case I ever need support.

So the main question is:
Is expanding the main disk considered the recommended production setup for Cloudron mail servers?

Or is using a dedicated volume for mail storage also a common and supported approach?

2. Backups

Regarding backups, my doubt is specifically about data located on a secondary disk.

If I move /home/yellowtent/boxdata/mail to another mounted disk:

• Will the Cloudron backup system still include it normally?
• Or are there caveats when the data directory is located on another filesystem / mount point?

---

I'm not trying to customize Cloudron unnecessarily — I'm mainly trying to understand what a good production storage design looks like when Cloudron is used as a mail server with ~1TB of mail data.

Any recommendations or real-world setups from other users would also be very helpful.

Best regards,
Diego

Hello guys,

I've been using Cloudron for many years, mainly using the native email feature with the SoGo app. I'm very grateful to the Cloudron team
Using it installed as a guest in a Proxmox environment.

Now I have a new need to host about 60 email accounts.
I need to provision about 1TB of space.

I would like your opinion on this.

Currently, the main disk where the system runs is 100GB. I would like to attach a second 1TB disk to it.

What backup strategy should I use?
Does the PRO license already cover this scenario? Or should I use the Business license?

Which filesystem should I use in this new disk for better management and security of these emails?

How do I allocate this new disk/partition/volume for the Cloudron email function?

Best regards,
Diego
