Feedback on immutability

olivierlambert

It is already working with any external S3 supporting immutability. It's exactly the same concept, but not on-prem You just setup the retention in your S3 console and that's it.

@olivierlambert Awesome, I'll test this as soon as I can and try to post about my experience with it. If all goes well I'll do a writeup/how to.

Thanks!

tried to run it.

Node.js v18.19.0

If everything works well, you can then start it as a service, for example with systemd (we'll provide an example service file).

still nope

Ping @florent

florent

@Tristis-Oris in the toml , the string should be between quotes

so liftEvery = "1h"

olivierlambert

We need to correct the blog post then

rtjdamen

@olivierlambert we are using synology nas as backup repositories, do u have any experience with them on this subject?

olivierlambert

Not specifically with them, but if we can run a program inside this, we could have immutability (maybe you can even configure it at Syno level?)

Synology has a developers program, which people can join, through this it's possible for a version of the immutability service developed for Xen Orchestra, to be deployed as a packaged program on one of their NAS products.

https://www.synology.com/en-us/support/developer

Check out the above link for more information.

@john-c @olivierlambert i have installed nodejs on the synology box, i installed the application

i am not shure if it actually is installing, i tried to go to /etc/xo-immutable-remote/ but the directory is not there, do i need to create it or should this have been installed?

rtjdamen

I created the directory and config file and tried to start the application but it get the follwoing error

Things on a NAS especially Synology NAS is different, as its not a normal Linux. It's been customised and developed by Synology so the structure is different, also packages may be missing that are expected as well as different versions.

So may be worth working with Vates on a Synology developer account and then having a GitHub repository with a port for the Synology.

rtjdamen

@john-c ok, @olivierlambert any chance we can get someone to look into this?

rtjdamen

@john-c @olivierlambert i will check out with our own developers what we can do on this subject, maybe we can help develop a draft application/package here. keep u posted on the results.

olivierlambert

We are pretty busy right now (release week), but we'll try to take a look later (@marcungeschikts will try to find someone available later on)

rtjdamen

@olivierlambert i understand, i will let u know the results on our end as well.

john.c

When working on this later on it maybe worth checking out lru-cache to see if inflight can be replaced. Due to inflight not being supported and leaks memory.

rtjdamen

@olivierlambert any update on this item?

rtjdamen

@olivierlambert Hi Olivier, it is pretty quite on this subject for a while now, any news or updates to expect?

olivierlambert

Hi,

Immutability is still possible via your S3 provider or via the Linux script we provided. It's still in the backlog to see how to get it integrated with 3rd party providers.
