The Ark [example/nginx-app/with-pv.yaml][2] serves as an example of adding the pre and post hook annotations directly
to your declarative deployment. Below is an example of what updating an object in place might look like.
Place Ark in to restore only mode. By placing Ark in restore only mode you prevent Ark backups from running
while you are adding the annotations and avoid the condition where the pre hook freezes the file system, but
there is no post hook setup to unfreeze the file system.

kubectl patch -n heptio-ark config default --type merge -p '{"restoreOnlyMode": true}'

Now you patch your deployment with the required annotations.
Now you patch your pod with the required annotations.
kubectl annotate pod -n nginx-example -l app=nginx pre.hook.backup.ark.heptio.com/command='["/sbin/fsfreeze", "--freeze", "/var/log/nginx"]'

Finally, remove Ark from restore only mode and test the pre and post hooks by creating a backup. You can use the Ark logs to verify that the pre and post
hooks are running and exiting without error.
