Subject Re: Local node SEGMENTED. Data Lost on a Partitioned Cache with backups of 3

Data loss can happend if rebalance is not finished by some reason between
nodes failures.
Also you can loss data that is being loaded from segmented node when
failure happens.

Would you please attach ignite configuration?
