The `retainOnDelete` resource option may be what you’re looking for: <https://www.pulumi.com/docs/intro/concepts/resources/options/retainondelete/>

<@UDWGK72BY> bingo! thank you. this is cleaner than pulumi state delete.

Another approach is to separate resources that you want to create or delete at different times into different projects. If you want to retain the log resources, they could be put in a different project.

This has the advantage that you can have separate log resources for different iterations of each stack of the main project, if you want. For main project "app", stack "staging", you might have log project "app-log", stacks "staging-1", "staging-2", etc.
With retainOnDelete, when you run `pulumi up` again, you'll get naming conflicts (unless you delete the log resources or change their names in code).

<@U012UJTT55M> why would naming conflicts occur? pulumi up appends a randomly generated 32-bit integer suffix that it appends to resource names during creation, so i wouldn't expect a naming conflict to occur.

Because it's the same resource in Pulumi state, so it'll be creating the same resource in AWS or wherever. But the resource still exists there, Pulumi has just forgotten about it.

It'll try to create the resource with the same random suffix. (It's not a 32bit integer, it's a 6-character alphanum)

e.g. i have <https://us-east-2.console.aws.amazon.com/cloudwatch/home?region=us-east-2#logsV2:log-groups/log-group/$252Faws$252Flambda$252Fmbrownhelloworld-Greeter-SayHello-func-789f7af|/aws/lambda/somelambda-func-789f7af> now so if i regenerate the stack i would expect <https://us-east-2.console.aws.amazon.com/cloudwatch/home?region=us-east-2#logsV2:log-groups/log-group/$252Faws$252Flambda$252Fmbrownhelloworld-Greeter-SayHello-func-789f7af|/aws/lambda/somelambda-func->&lt;newRandomSuffix&gt; to be created instead

6 chaaracter alphanum != any kind of integer :slightly_smiling_face:

It might use a new string, true. I haven't tested this. I've assumed that the suffix wouldn't be regenerated because it's the same instance of the resource.

in all of my resources i am seeing a 7 character hexadecimal string which is a representation of a 28-bit integer.

Ah yes. I was being too programmery. `const x : number = "789f7af"` won't ever work :)
