I used the word 'gravitation' also for backup data, may be improperly.

This movement of the primary data that are without backup can cause a "network storm", but this is inevitable.
Why there isn't an equivalent movement for the backup data that are without primary (e.g. /_BUDDY_BACKUP_/192.168.0.4_33266/one on cache) ?
My major concern is not related to the "network storm" but to the fact that in case of multiple faults the cluster has information loss. For example: Let suppose that first the cache dies and then after one minute also the cache dies. In this case the data stored in the node /one is lost forever.
Thanks and regards
