I'm in the process of migrating to WP Engine. Fortunately, before I migrated any sites, I noticed a support article from WP Engine stating that they disable revisions by default. That article and other information I've seen from them also, thankfully, state that revisions can be enabled by request.
When I requested that unlimited revisions (normal WordPress behavior) be enabled, a support agent said they would only enable up to five revisions.
In addition to arguing that this limit is not stated anywhere in any of their articles, pre-sales information, or anywhere else (they only state "recommended" limits and that more than those recommended limits can be enabled, implying there is no limit) and telling him all the reasons (unlimited) revisions are crucial for me, I'm wondering if I could also say something about the lack of logic in placing a limit on revisions when there is no limit on the number of posts or pages allowed. Someone whose sites have thousands or tens of thousands of posts and five revisions enabled will cause far more "database bloat" (the reason they say they disable/limit revisions) than my little sites with only hundreds of posts and unlimited revisions ever would.
First, am I correct about that policy inconsistency, or is there something I don't know about revisions that cause them to "bloat databases" and "impact servers" more than posts or pages do?
Second, have any of you who use WP Engine successfully had more than five revisions enabled?
Finally, if I absolutely can't get them to enable more revisions, do any of you know of any way I could automatically save old revisions before they get deleted by the sixth and subsequent revisions?
Thanks.
