I'd forgotten Proxmox Mail Gateway - thanks for reminding me. I've been considering using Synology's mail server at home, having additional
security in front of it would be helpful. I already run Proxmox VE and
their backup server...

If you already have a Proxmox VE then the easiest path for you is to spin up a virtual machine and install iRedMail on it. Or any iRedMail alternative at that. If you are taking 5 concurrent users top then you need nothing more complex than this.

If I was to move to Proxmox (which I haven't ruled out), I would want to ensure backups and restores are very painless, allow restoring part or all of an instance, or the ability to mount a backup and pull files from a virtual disk.

Proxmox backup is like restic for images of virtual machines.

Things to consider is Proxmox Backup (server) is desgined for being used by the Proxmox Virtual Environment mainly. It is not like they make it easy to push backups from non-proxmox and to non-proxmox. You can kind of do it but that is not what it is designed for.

Proxmox backup is mainly designed to take snapshots of your virtual machines and restore snapshots of your virtual machines in an atomic operation. This means you are not going to be able to fish for a single TXT file in your backup pool if you want to restore it. With Proxmox you get to restore the whole virtual machine or nothing. (Proxmox actually has a host mode but I don't think many people use it).

Basically, the idea with Proxmox backup is to be able to recreate your virtual machine fleet if your favourite elephant steps on your Proxmox VE server or something. And it is very good at that, btw.

The advantage of Proxmox backups are that you can take differential backups very quickly and keep a historical archive in an automated way. This is, you can take a daily backup if so you wish and every time you take a new snapshot only changed data blocks will be stored, so the whole operation is relatively quick. Proxmox backup also lets you restore from different points in time (say you discover a file was lost a month ago but you just realized today. You can restore your virtual machine from a snapshot just before the file was lost).

Perfect for a homelab - thanks for the pointer!

Exactly what I thought it would be and nothing more - which is great, and
being able to pull files individually, not critical, but if I needed to pull
a file, or folder, or database, or something, and not interrupt the
production VM, I assume one could restore to a separate VM instance or to a different VE node, boot it in isolation, extract the content required and
move it off to the prod VM?

One should be able to expect that in that month, many other items would have also changed, if you get my drift...

It makes sense that it works at the hypervisor snapshot level - my Veeam does that too - which is ideal! Veeam just gives me the ability to customise the restore, even pull a single email out of the Exchange database should I need to! Just wish it supported Proxmox - I'd already be using it :D

Again - I need to grab my proxmox box off the shelf and give it a whirl... I just don't have the rack space, bench space, or the time right now to have a play!

Do you know if Proxmox has Dell OMSA support?

If you are a cheap sort of person you can keep your production VM running and restore an old version of the same alongside it. You get the option to assign a different MAC address to the restored copy which is handy if you are the sort of person who uses pseudostatic DHCP/DNS for identifying your VMs. Just invent a new MAC address for the restored copy, then point your DHCP/DNS to it, and your restored VM is instantly reachable without interfering with the production VM.

Nothing official, but since Proxmox has a Debian base you can bolt support on it without too much difficulty.

Nice thanks.

Looks quite promising, most of my servers these days are Dell. I have a
couple of HPE MicroServers, but they don't do any heavy lifting.

Hello I wanted to discuss Proton and the several services they provide.

What is y'alls opinion on e.g ProtonVPN, Proton Mail?
I'd like to know :3!

I am a Proton Mail user myself. I used to use Google Mail but it's
proven relatively unusable for me. .----.

I've not used it, but there's a podcaster I listen to that uses Proton
Mail...

I just learned about another one that offers free IMAP: mailo.

I've been looking to change away from gmail, just haven't found the
right solution yet, this one has the features I want and the price for extra storage is reasonable.

Our school system uses Google, so I have a gmail account for personal.
I can use command line tools for both 'drives' so I've stuck with it,
but now I'm wondering if I wouldn't be better served with something
less 'corporate.'

Let us know what you think if you try it!
