How to Enable Automatic Zookeeper Backups in Exhibitor?

[Traiano Welcome]

(It appears the exhibitor wiki is missing this specific piece if information - I'd appreciate it if anyone could suggest how to configure it?)

I have exhibitor installed on a 3-node zookeeper cluster.
I'd like backups to be executed automatically per node.
I can create an "index" manually via the UI and restore.
However, I notice that the index is only once-off.
Exhibitor doesn't appear to automatically backup indexes.

- My exhibitor configuration is as follows:

 cleanup-period-ms=300000
 check-ms=30000
 client-port=2181
 connect-port=2888 
 cleanup-max-files=20
 backup-period-ms=600000
 backup-max-store-ms=18000000
 observer-threshold=0
 auto-manage-instances=0
 backup-extra=
 log-index-directory=/var/zookeeper/snapshots
 zookeeper-log-directory=/var/log/zookeeper
 zookeeper-data-directory=/var/lib/zookeeper
 zookeeper-install-directory=/usr/local/lol

- I start exhibitor service using this command line:

 java -jar /opt/maven/target/exhibitor-1.6.0.jar --port 8181 --defaultconfig /nfsshare/exhibitor/exhibitor.properties --filesystembackup=true --hostname `hostname` --servo=true --configtype=file --fsconfigdir /nfsshare/exhibitor

Am I missing some particular settings that enable automatic / scheduled backup of zookeeper state?

Some Additional information:


see an index listed after creating on in UI, and clicking on the index I indeed see a list of entries I can restore.

When I click to create "New Index" I see the following logs are generated, leading me to believe the backups are not being created:

I'm not sure how to explain the "Index Build: there are 0 available backups" message, though.

I had the same issue . While i did remote debugging i found that that i had version-2 included in the data directory pathname. Removed it and that  did the trick.
