                                               --k8s-namespace
                                               [--use-k8s]. The 1th example of the child command would be to use it to 'linux   restore a backup taken from a previously run  arcdata dc debug copy logs  command', the syntax is: az arcdata dc debug restore-controldb-snapshot -k arc-data-services -f /path/to/backup/controller-1675653451.bak. The 2th example of the child command would be to use it to 'windows   restore a backup taken from a previously run  arcdata dc debug copy logs  command', the syntax is: az arcdata dc debug restore-controldb-snapshot -k arc-data-services -f C:\path\to\backup\controller-1675653451.bak.
