 Yes, with some exceptions. For example, when Ark restores pods it deletes the `nodeName` from the
 pod so that it can be scheduled onto a new node. You can see some more examples of the differences
 in [pod_action.go](https://github.com/heptio/ark/blob/master/pkg/restore/pod_action.go)

+## I'm using Ark in multiple clusters. Should I use the same bucket to store all of my backups?
+
+We **strongly** recommend that you use a separate bucket per cluster to store backups. Sharing a bucket
+across multiple Ark instances can lead to numerous problems - failed backups, overwritten backups,
+inadvertently deleted backups, etc., all of which can be avoided by using a separate bucket per Ark
+instance.
+
+Related to this, if you need to restore a backup from cluster A into cluster B, please use [restore-only][1]
+mode in cluster B's Ark instance while it's configured to use cluster A's bucket. This will ensure no 
+new backups are created, and no existing backups are deleted or overwritten.
