Each filer has its own local change logs. `weed filer.sync` will read the logs and replay them in the other cluster.
`weed filer.sync` also remembers each filer's "signature" and replication checkpoints. So you can stop `weed filer.sync` and start it later safely.

Also, the "signature" will ensure same change will only be applied once in one filer. Active-Active synchronization would not cause multiple ping-pong changes for one file update.
