Hey, No, don't restart regularly, high memory usage is good, because unused memory = wasted memory! Hexos is using the memory for the ARC cache, this is a read only cache where Hexos is preloading files which it believes you are using next and can then deliver those files from the memory instead of having to read them from the drives. Depending on your current usage you will not notice any performance boost with more memory, but you might future proof it. Memory prices are currently going through the roof, only buy memory if it's not overpriced.

Oh nice thanks, yes that works.

Can you please also post more details on your HDDs? Those might be SMR drives which will likely cause a lot of (performance) issues in the future.

Hey, Backups are done over the local network or Internet (which requires additional setup) and are done using the existing network connection. Using an USB cable to connect to your server is not supported. What exactly do you want to backup from your devices? There are different ways and apps, depending on what you want to do. Backing up pictures from your phones (and Mac maybe?) you can use Immich, which is a one click install app in Hexos. For documents you could use something like paperless, which requires manual loading of the files and is more like a document manager, rather then a simple backup solution. And there are other solutions to backup every kind of data. For your family, not living in your house, to be able to backup to your server you need to either setup a VPN or Cloudflare Tunnel or similar. Hexos is using ZFS and in ZFS it's called RaidZ1 and not Raid5 🙂 Also please post your specs of your Server which you want to use, this way we can identify possible incompatibilities and issues beforehand and mitigate them.

Hey, yes this is a good idea, I currently have a similar setup, Hexos as main Server, Unraid as on site backup and a synology NAS as an off-site backup, planing to replace Unraid with Hexos once the HDD prices are normalising again. Let's first start with backups: Since Buddy Backup currently isn't available, you will need to setup the task replication in the truenas GUI to backup to your other Hexos. Since this is not in your local network you need to setup a VPN connection or URL or similar to be able to connect both server together. For the backup to your Unraid, you can use rsync to backup to it. Having app failover is an entire different and way more complex topic. The above backup is only creating snapshot but it's no live backup meaning it cannot be used for app failover since the data is not live. Hexos/Truenas Scale doesn't have app failover support, this is exclusively reserved for the entireprise stuff. I know that some apps have some way to have this, but this depends on the app and requires additional setup per app etc. The easiest thing would likely be running everything in a VM in proxmox and have High Availability setup, but this comes with it's own set of restrictions. Unfortunately, there is no easy or moderate complex way to set up app failver

Truenas itself already offers a lot of possibilities, you have the standard rsync which you can use to backup to virtually any other type of NAS and you have the replication task which you can use to backup to another truenas/hexos server. If you're looking for options for more tech savvy users, truenas already offers them, there is no need to wait for Hexos to implement them. 🙂

The difference is pretty big, while they do the same thing, they do it very differently. Immich just stores all the images in plain on the file system, all the processing is done on server side, you can connect an external library and if your Immich DB or installation becomes corrupted or breaks and there is no more support for Immich you just take the photos folder and move on. But the admin and everyone who's access to the folder can see all the photos of everyone, so privacy is not that great, but administration is easier and recovery in case of an issue is easy. Ente (FunFact: Ente is German for Duck) is all about privacy. The photos are all encrypted on the server and only the client side can decrypt/see the photos. This also means that the client side needs to do all the processing, but therefore the server can be very low spec (although this doesn't matter in our case, because Hexos needs to run in the first place, so HW specs is not really a concern in any way) and it needs S3 storage and requires more setup an administration. However if your Ente DB becomes corrupted or the Ente app breaks or the Ente dev stops and your app becomes unusable, you lose all your photos, because you cannot access it any other way. But until that happens only your client side device can access the photos and no-one else can.

Hey, no this will not work as you've described it. With 2 drives Hexos will automatically create a mirrored pool, meaning your data will be stored on both drives at the same time and you will only have the capacity of 1 drive but you can lose 1 drive without losing data. You cannot create a Pool without parity with more then 1 drive. A RaidZ Pool type cannot be changed after it was created, so you will be stuck with your mirrored pool and you cannot expand it. If you then throw in your 4 drives from the old NAS, Hexos will create a new RaidZ1 pool, which has the capacity of the numbers of drives -1 (capacity of 3 drives in your case). You can then copy the data from your mirrored pool to your RaidZ1 pool. If however, your mirrored pool does not have enough capacity, get yourself a 3. drive to create a RaidZ1 from the beginning, copy your data over and afterwards add your drives from your NAS to the pool or create a new pool. (expanding a pool can only be done with 1 drive at a time and takes some time). Also make sure all your drives have the same capacity or else Hexos will not group them together.

It's always clearly described who gets what, on the main page, in the forum post and in the email. The only way you don't know the different prices is if you just blindly click a link in this forum without reading the corresponding posts. 🙂

1 system/installation requires 1 license. And Buddy Backup is between 2 systems requiring a license each. The owner doesn't matter all you need to have is 2 Hexos installations/servers therefor 2 licence in total and you are good to go for buddy backup.

So, Buddy Backup only works for different users? I bought 2 licenses a year ago to be able to do buddy backup with myself, so that's not possible? I would need to fall back to Replication Task over SSH ?

Hey, Buddy Backup isn't currently available and Hexos doesn't offer anything to do a backup to another machine. However if you login to Truenas go to Data Protection and there to the Replication Tasks. You can setup a new Replication task there following this guide: https://www.truenas.com/docs/scale/25.04/scaletutorials/dataprotection/replication/ But this requires that you can connect to the other server, via tunnel or domain name or sth. Similar.

Hey, No this has been fixed months ago, with the Q1 update I believe.

Hey, It seams to be possible to use a GPU with multiple apps, but you need to login into truenas to do this: https://www.truenas.com/community/threads/can-multiple-apps-utilize-the-same-gpu.99757/#post-712876

In addition to what M said, low idle power draw doesn't necessarily mean, low performance hardware, modern high performance HW also has amazing power savings potential & idle power draw, so you don't need to go low performance, or old HW. Some easy wins are disabling unused HW/parts in the BIOS (Audio, onboard NIC if a dedicated NIC is used, Wifi etc...)
