Is there any way to make sure data and its backups in different data center

[c c <ye...@gmail.com>]

HI, we are working on ignite v2.7.0 . We plan to deploy 5 server nodes
across two data center (three in one data center and two in the other). We
setup 2 backups for each entry, so we have three copies data for each
entry. How can we make sure there is at least one copy in both data center?

Regards

Hello,

You can set custom affinityBackupFilter in RendezvousAffinityFunction. See
[1] for example.
