Aled Sage commented on BROOKLYN-559:
------------------------------------
There are two reasons for this:
1. The fundamental reason (IMO) is that it should copy the state as-is (i.e.
raw copy, rather than any deserializing/reserializing). It seems that
'checkpoint' to the backup dir does some processing that can go wrong.
2. The specific warning comes about because the original bundle from persisted
state no longer exists. Instead, the initial catalog has already installed the
equivalent bundle. When we come across the persisted state bundle, we see it is
identical and skip it. However, this means that the id of the
{{BasicManagedBundle}} representing that bundle has changed. When the
'checkpoint' tries to find the managed bundle with that id, it can't so it
skips persistence of the jar file!

> Issue Type: Bug
> Reporter: Aled Sage
>
> To reproduce with 1.0.0-SNAPSHOT, simply start a fresh brooklyn (persisting
> to a new empty persisted state), then stop it and start it again.
> What should happen on restart (for file-based persistance rather than S3, at
> least) is that it backs up the persistence directory before modifying it at
> all:

> However, it does not back up the bundles from the {{/bundles}} persistence
