Hello everybody,
my plan is to switch from Android to GrapheneOS. In this process, I want to get rid of my reliance on my google account as much as possible.
To this end, I’d like to selfhost some “critical” data, e.g.
- contacts
- calendar
- online drive for files (e.g. google drive alternative)
- some basic note-taking app (like google keep)
and so on.
I do some selfhosting already, though it is not that kind of “cannot lose this” data. So I’d like to share my thoughts and ask for your opinions and experience for the process.
More details for what I want
contacts
- have to be syncable to the phone
- if possible, some webinterface to edit / browse
calendar
- has to be syncable to the phone
- webinterface + sync to desktop / phone
- if possible, send invite-links to events to others
drive
- files of my choosing must be offline-available
- ever other file should not use storage on the phone
- if possible, able to share links to download files
- if possible, able to share links to view with online editor (see below)
document editor
- think google sheets / google docs
- if possible, able to share links to view documents online
smartphone photos
- auto-backup camera folder
There may be some things I’m not thinking about right now, but this seems to pretty much be it.
If possible, all of this should be accessible only via vpn.
What I already have
I have a pfSense physical appliance that’s already managing my home network, got an OpenVPN already setup, dynamic DNS working properly for the lack of a static IP, etc.
I own 2 mini-PCs (some Intel NUC, some passive-cooled zotac with an intel with 4c/8t). One of them (zotac) is currently running as my Proxmox Virtual Environment Hypervisor, managing 3 VMs.
I also have a second PC which misses some critical parts, so it is not currently in working condition. I think there’s an AM4 mainboard and 16 or 32GB of DDR4 RAM in there. I could make a NAS or a new hypervisor out of this, but the case (Fractal Design Define 7) is quite big and a full PC is probably worse for energy-efficiency than my 2 mini-PCs and is going to be more expensive.
Not much in terms of storage sadly
- 1x 6TB external USB HDD (used for backups)
- 1x 2TB external USB HDD (used for data)
What I plan to do
The kind of data I’m going to be hosting myself now is very import, so it cannot be lost or corrupted.
But the feature list doesn’t seem to be overly complicated. This seems like something nextcloud could do.
This means, I will probably need to buy
- 2x 4 TB HDD for storage for data RAID
- 2x 8-10 TB HDD for backups
- 2x external RAID case
Then I could connect the data RAID to the already running zotac pc and spin up new VMs for nextcloud and whatever else I might need and start serving my data from home.
The Intel NUC will be used as a Proxmox Backup Server, connected to the backup RAID. Keeping some daily, weekly and monthly backups.
On the phone-side, I’d have the vpn always active. Whenever active, sync of contacts, calendar entries, photos etc. should be possible.
Questions
Is there anything I missed? Did any of you already try something like that? Does anybody here see a potential problem with any of the above?
Can anyone recommend a RAID-1 external enclosure without a fan and some quiet and energy-efficient HDDs?
Thank you for sharing your experience of the process!
I’m a little confused after looking at the website. What exactly does DAVx5 do? The regular re-sync of contacts, calendar and files itself? Shouldn’t that be done by the contacts app / calendar app on regular intervalls?
I just downloaded fossify calendar on my android a few days ago to test it and got to see the other fossify apps :)
Oh man, I already use syncthing for ~5 GB of files and I use it on my android too. Seems I’ll be trying syncthing-android-fdroid in the future then.
There really are a lot! NotallyX looks nice and simple, but memos also looks very interesting. And thank you for the link, I’ll go dive into that tomorrow.
I do not need RCS-compatible messengers. What I send via SMS is nothing more than pure text, also no group chats. I use signal and element for my “fancy” messaging needs :)
I’ll look into it some more over the next days, but on a quick glance, this seems like it is an online service where you need an account? If that’s the case, I’d prefer using my already running OpenVPN server to do the job.
DAVx5 basically acts as the connector between your server and your calendar/contacts/files apps. I would imagine that this could be built into an app, but there are a lot of ways that such apps can sync or operate locally. I’m guessing that it is just a little more specialized than most developers want to get.
Thanks for the Syncthing-Fork tip! For now the official version is working for me, but I’ll have to migrate myself soon.
From my understanding, OpenVPN provides the same secure remote access as Tailscale, by a slightly different method. You should be fine to use what you’ve already set up.
Thank you for the explanation. I’ll probably be testing a lot of FOSS apps on my current android before I make the switch, so it’s good to know that I have to look out not just for usability, but also connectivity!
