Since a couple of weeks I am getting warnings on my HA that the space is “less than 2GB”
I was expecting it to grow a little bit since the (last?) update where it explicitedly declared that this was expected.
But I have already added a couple of GB more to my VM a couple of times and it keeps asking for more. The system sits at around 30.6GB at the time. I keep my backups on a Mounted NAS and one in the same system.
I Will give more megas to my VM but I have the feeling something is dangling there.
I have not found any tmp folders that could be problematic. Does someone has some tips what can I do to check if something is unhealthy with my install?
My system looks like this:

I would start looking at the backups, DB and “Log-Files” , As you don’t mentioned “Alot” in regards to Your System-Setup, It’s just “Shots in the Dark” answers you will get
That was “details” i like … Nothing really “sticks out” , But Your Piper, Wisper , And Speech-to Voice, Which can “contain” endless Datas
But as you have access to Terminal try with du -sh , but also check /var/log.
Maybe df ( docker system df “You need Advance Terminal APP , for this” )
Well, i wouldn’t know, and not even sure a Full backup would help you if that command removes " more than “intended”
You have alot Add-Ons so naturally also alot Containers
But the amount of DATA ( In Images ) sure looks like it’s Your Add-Ons ( APPS ), You need to focus on.
( On the other hand, it also include HA’s “native” Containers )
Either Move DATA to a dedicated DATA-Disk, via the UI-Feature
Again Piper/Whisper/Speech-too-Phrase can be Your “issue” depending upon how much you have “loaded” into these
PS: I Just noticed you are running a VM , if you shut it down, and copy the whole VM Images, then you could try to see if you have “old” stuff “dangling”, thou i doubt it will “release much”
I still believe that those 3 mentioned APP’s is not mend to be running inside a “small” HA Install
Above System Spec, also says nothing in regards to your Hardware, i.e Dedicated CPU’s, Ram.
Not that it’s of interest in this matter, Thou the 3 mentioned APPs add’ another “dimension” to the CORE-Functionality , And can be very resource demanding “interrupt/slowdown” main purpose/functionality
The system is running on a mini pc with 16GB of ram and 8 x Intel(R) Core(TM) i7-4785T CPU @ 2.20GHz (1 Socket)
I did a prune at the end and I just really got like 400MB more of space.
I am looking at the images I have a couple of big containers but nothing looks like was getting bigger and bigger (of course I have no from months ago)

Maybe I need to focus on the DB. The sunny days are starting on my side of the globe and my (NEW) Inverter/Solar/Battery seems to be kind of noisy
This tells you the problem - you have 25 containers (count your addons) installed and running with 4 images not running - you could reclaim the 4 not used but the 25 in use prob make the bulk of that 27G.
Read: You must construct additional pylon... er sorry wrong software - you need more space. Or you need to pull addons / apps out.
Yes maintaining good db hygiene is important dont NOT do that… but your db size will stabilize as after 10 days history starts to take over and help you clear the chaff long term. Your big problem is static storage rn.
That said. you asked how big can it get? My BACKUP ALONE is 13 G - so… You prob need to look at more storage long term. My system volume on my HA box is currently 128G, but I’m about to double that as I get too close at the end of the month to 75% after my backups. 48 will be TIGHT no matter how you slice it.
Your DB is fairly “small”, And overall nothing really “sticks out”
Thou again the 3 “mentioned” APPs, is takes about +4Gb ( Really not much )
However as Nathan says, You need to Adapt to Your reality , Add more Space
I mostly keep my backups on a NAS, and for catastrofic failures depend more on the full VM backup to be honest, but yes you and @boheme61 are right. I need to think about my space, I try to keep it around “just what I need” because one I went uncautious and got a full storage error on my proxmox instance at. 10pm not fun.
