Hi, I am in the process of setting up regular backup of zookeeper data directory. Is there any documentation available on the recommended tool/method or issues to be aware of? Some of by doubts are: 1. what is the recommended frequency of backup? is there any case where zookeeper may decide to get a complete data dump instead of using the latest snapshot and replaying transactions? 2. from my understanding after reading the zookeeper administration guide, zookeeper starts a fuzzy snapshot after a configured number of operations. for backing up we need to take the latest snapshot and the transaction log file. how do you avoid copying the snapshot when zookeeper is in the process of writing the snapshot file itself?
It would be helpful if you can provide me some pointers on the possible solutions. Regards Damu
