Hi,
I'm running Orchestra from source, last update 2/3 days ago and since some days ( I suspect after one reboot of the server i did) I have a strange behavior. All the backup jobs are running twice, doesn't matter which one Metadata, Snapshot or Delta. I attached a screenshot.
Did someone had the same issue?

Hi, actually I'm storing the Backups on a Synology NAS, but for what I understood actually i cant' enable the feature "Write Once" on the NAS because even if I have a retention for example of 10 Daily Backups, and file locked for 5 Days on the NAS, every daily backup XOA is doing something, like updating json, etc.
Is that correct? Or I'm missing something and there is a way?

@olivierlambert If you want me to check anything else, just tell me and I will test for you.
Many Thanks

@olivierlambert below you see two bacups on the stat, The first is with NDB and the second without.
@olivierlambert Thanks a lot for the quick reply. I checked with the command "xentop" on my server.
When I run the Backup, with or without the NDB the CPU increase from 50% to 120-160%.
Now I'm testing one backup per time, and what I see is that in both scenarios the transfer rate is: 110.18 MiB/s so almost the 1 GB. SO I think the bottleneck is the network. I mean on the Hypervisor I have 2 GB because I have the LACP, but the Virtual NIC of the XO is 1G.
Did I unterstand correctly?
Thanks

Hi all,
sorry I'm not expert and I would lik to ask you clarifications regarding the network protocol NBD.
I'm using the last version of Orchestra (update today) from source, and I'm testing it with Xen Server 8.2.
I did a full backup of one VM and it took 27 Min.
• Duration: 27 minutes
• Size: 99.87 GiB
• Speed: 63.32 MiB/s
Than I did it again with NBD (4 connection) and the result is the same.
• Duration: 27 minutes
• Size: 99.87 GiB
• Speed: 63.25 MiB/s
I can confirm the NBD because now I see also the text (Transfer data using NBD).
CBT I can't test for the moment because the XenServer has only the standard license.
Can someone explain me a bit more in detail how it works?
Many thanks in advance

mmm ok. Let's take an example. Full disaster recovery. I have my backups on the NAS but I lost everything and I have to install everything from scratch.
What are the steps I need to do? What I imagine is:
After that I can restore the metadata and backups, and also the shared storage will be reconfigured automatcally?
Are more or less those the steps?

Marco
@nikade yes I will do.
Easy question. With Xen actually I use also the Windows APP Xen center to manage the pool.
With XCP-ng if I undestood correctly will be used Orchestra as management tool, right?
In that case would be better to have Orchestra as physical server outside the Hypervisor environment? or?

@nikade Sorry for the late answer. At the moment running the free version, but I would like to switch to supported one, because we are a company and we want the systems and the support really reliable.
There is something interesting that attract me in the project. Maybe I will ask a demo to @olivierlambert to go deep in some aspects.

Marco
@olivierlambert Yes I know, I'm evaluating several solution, also the Xen 8.2 and yours.
I still don't have clear idea, I have to read more about your xcp-ng
Thanks for the support
