AEM has a great feature, that if you delete pages, then you can restore them at a later point.
Is there any limit to when you will no longer be able to restore the pages? I.e. after a Tar Optimization or similar? Will this purge deleted content content? Or is maintained forever as part of the CRX version history?
regarding purging of versions - you can configure the behaviour of the versions purge service via osgi configuration (Day CQ WCM Version Manager) - default setting is to not purge any versions (but you can change this :-)).
The basic assumption is, that you should always be able to get back to the latest version of a deleted page (if you delete a page, you will automatically create a version; at least that's part of the authoring interface but AFAIC not of the basic API implementation). Do you really want to get rid of every possibility to every restore a deleted page?
No - just asking the question in case they were to get deleted behind the scenes. The question came up (would they ever get purged) from a User after looking at the restore feature during Training, and the answer wasn't clear on the documentation.
