32 GB should be plenty of RAM for this scenario.

tl;dr Duplicity does full or incremental backups, BorgBackup only does full backups but with deduplication.

After the first backup with Duplicity, you can choose to do an incremental backup which will only store the data that has changed since the last backup. This saves time and disk space but you have to do slow full backups regularly. See question 3 of the FAQ.

BorgBackup alway does a full backup. But it divides all data into chunks or blocks (don’t know what they call it exactly at the moment). It then hashes those chunks and stores them in a content-addressed storage layer. So it basically works like Git under the hood (plus encryption). If a chunk doesn’t change between backups it‘s already there and does not have to be stored again. A backup is always a full index of the data.

With today‘s fast processors and hashing algorithms, a backup with Borg should be just as fast as an incremental backup with Duplicity. If you ask me deduplicated backups are just plain superior.

Another tool that works like BorgBackup is Restic, which I prefer. Both are good choices that I would trust with my data.

Great, I accidentally deleted my original comment because the Lemmy web interface doesn’t ask for confirmation when you click the delete button. And the buttons are so small on mobile that it‘s really easy to click the wrong button.

If you want to use these features for security, access them manually. But, OP said they are kind of a noob. Telling them to just use containers is dangerous and leads to false assumptions.

You are absolutely correct. I should have stated explicitly that I didn’t mean docker and/or using pre-built container images. I was talking about something like systemd-nspawn. And you are right that I should not have brought this up in this context. I will edit my original comment.

So, putting a process in its own network, file-system, user etc. namespace does not increase security in your opinion?

I see. That‘s a valid use case. Although, in the spirit of self-hosting, I personally would either get another ISP or run a reverse proxy on a cheap VPS and connect the homeserver to that via Wireguard.

Why would anyone DDOS a random home server? I don‘t think OP has to worry about that.

Could you please be more specific what exactly Crowdsec brings to the table? In which way does it “secure the network”?

Where was that? At least the part where they force you to buy the book from their website or the college store would be illegal in the EU. (I am not a lawyer.)

I don‘t know what specifically you would like to know and what your background is, so I will just elaborate a bit more.

The basic idea is that the VPS, which is not behind a NAT and has a static IP, listens on a port for WireGuard connections. You connect from the NAS to the VPS. On the NAS you configure the WireGuard connection with “PersistentKeepalive = 25”. That makes the NAS send keepalive packets every 25 seconds which should be enough to keep the connection alive, meaning that it keeps a port open in the firewall and keeps the NAT mapping alive. You now have a reliable tunnel between your VPS and your NAS even if your IP address changes at home.

If you can get a second (public) IP address from your provider you could even give your NAS that IP address on its WireGuard interface. Then, your VPS can just route IP packets to the NAS over WireGuard. No reverse proxy needed. You should get IPv6 addresses for free. In fact, your VPS should already have at least a /64 IPv6 network for itself. For an IPv4 address you will have to pay extra. You need the reverse proxy only if you can‘t give a public IP address to your NAS.

Edit: If you have any specific questions, feel free to ask.

I think Space Göring would be even more fitting. The Luftwaffe was like Göring‘s pet toy. Also he took a lot of drugs.

You could get a VPS only for getting around the double NAT.

Run a reverse proxy on the VPS and forward requests over WireGuard to your NAS. That way you wouldn‘t actually host any data on the VPS.

How many outgoing emails are we talking about? Because there are a lot of free or cheap options for personal use and small businesses.

You could try Consent-O-Matic. That’s what I use. It also doesn’t simply agree to everything like the other one but chooses the most privacy-friendly option instead.

Hadn‘t heard of Rumble. At first glance, it looks like it‘s run by Elon Musk. Andrew Tate on the frontpage, far-right political channels and crypto bros. I think I‘ll pass.

A reverse proxy does not magically make an insecure app secure.

Do you want pixel graphics, or do you want gameplay like Vampire Survivors? Because the suggestions here are all over the place genre-wise.

There‘s this great video essay that basically agrees with you. Rockstar want to create these cinematic narrative experiences but that does not mash well with their concept of an open world.
