Thanks Stefan, First of all, for a bit more context, we use this ceph cluster just for hot backups, so 99% write 1% read, no need for low latency. Ok so the snapshot function would mean, we would have like a colder backup. Just like a snapshot of a VM, without any incremental functionality, which also means scheduled but huge transfer rates. What about the idea of creating the cluster over two data centers? Would it be possible to modify the crush map, so one pool gets replicated over those two data centers and if one fails, the other one would still be functional? Additionally, would it be possible to prioritize one data center over the other? This would allow saving data from site1 to a pool on site2 in case of a disaster on site1, site2 would still have those Backups. We have a 10G connection with around 0.5ms latency. Thanks in advance, Simon ________________________________ Von: Stefan Kooman <stefan@xxxxxx> Gesendet: Dienstag, 8.

It's a work in progress [1]. This might do what you want to right now: [2]. Note: I haven't used [2] myself. Gr.
