Hi, In this post it has been mentioned that to manually take a snapshot of Ignite without using commercial solutions, we need to deactivate the cluster , copy work/db folder to our backup location and activate cluster. And to restore we deactivate, copy the backed up data and activate.
http://apache-ignite-users.70518.x6.nabble.com/Snapshot-backup-of-Ignite-native-persistance-data-tp20103.html When I was trying this, I faced these errors : 1. WAL error : On restoring it says critical WAL archive missing and the nodes crash. 2. Node Lock : This lock in node00-UUID folder is held from start to stop of a node. So deactivating the cluster will not remove the lock. I tried copying only the node00-UUID folders without WAL and I was able to restore my caches. Is this approach correct ? Will WAL overwrite the restored node00-UUID folders' data ? -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
