how can i make hot restore backup to cluster with the help of xtrabackup without stop cluster? Is it possible?
AFAIK, If you have a cluster with several nodes and you want to restore a previous backup to restore the data on all nodes then NO, its not possible to restore backup without stop cluster. Because hot backup doesn’t mean hot restore.
If you can describe your environment and exact requirement then there might be some workaround for this. There is one option import/export but I dont know how reliable it is. Need to test.
