ZRS (Zope Replication Services)
- Commercial product by Zope Corporation which prevents a single ZEO server from becoming a single point of failure.
- Replicates a ZEO server to N “secondaries”.
- You might need it.
- Alternately, consider “warm failover”, using “repozo.py” script which can back up an active FileStorage file incrementally to a separate system.
