Kirk Lund commented on GEODE-292:
---------------------------------

Wes, on the far right under People are Assignee and Reporter. Directly under "Unassigned" is "Assign to me" (a link in blue). You can click that to assign to yourself, or if you click on "Unnassigned" it let's you enter a name. I'll assign it to you.

>    Affects Versions: 1.0.0-incubating
>            Reporter: Wes Williams

> Backup/ restore using snapshots takes a very, very long time when:
> 1) There are a lot of PDXTypes, and
> 2) There are a lot of regions.
> Specifically, it takes 35 minutes to restore only 50MB of unstructured JSON from snapshots. In contrast, it takes only 3 minutes to reload all the data from scratch.
> PROBLEM
> CacheSnapshot loops all regions and saves all cache PDXTypes in every region.gfd. On restore, it reloads all cache PDXTypes again for every region where they only need to be loaded once.  
> SOLUTION
> This JIRA issue will create an option to save PDXTypes only once and reload them once and store only data in the region snapshots. Existing functionality will remain for those who want it.
