@florent "the export is done by one of the host of the pool"
How is this host selected ? Is it the master one, the one hosting the VM, or the less busy one in case of shared storage ?

@florent Hi,

Thank you.

And during backup which host is working hard during the vdi export to XOA (or to the proxy) : is it the host which contains the backed up VM, or is the master also doing some work (other than control channel calls) ? Through which host the network flow is going through ?

@florent can you confirm for the replication job ?

Thank you

@Pilow I was asking in the case where the sites are only allowed to communicate via HTTPS, meaning NFS remote at site 1 is accessible through proxy 1, and NFS remote at site 2 is accessible through proxy 2 (XOA being on site 1).

@florent @pilow
Thank you all, it is clearer.

Can backup copies between sites flow through one proxy directly to another,proxy or does it need to flow from one proxy to XOA to another proxy ?
In this case, could the XOA become a bottleneck ?

Thank you

Hello everyone,

I am trying to better understand the load/possible bottlenecks implied by the backup and the replication process.

Is there any documentation explaining in deep details how it works (the docs I could find are quite macro on this subject) ?
For example, regarding incremental backups, is the compression done by the source host, or by XOA ?
Is the algorithm zstd or brotli ?
And how do you scale up if you have more than 1000 VMs ? Do you distribute the backup jobs between multiple XOA, or upgrade XOA ressources, dom0 ressources ?
Do XO proxies have less abilities than XOA regarding backup and replication capabilities, and need to "lean" on XOA for specific functions ?

I know this is a lot of questions
Keep up the great work.
Thank you from Paris

@MathieuRA Thank you, perfect

Br,
