Frequently, a power outage will cause the memory in the Vantage's logger to become corrupt, causing the symptoms you describe. However, swapping databases would not fix this. See the wiki section *WeeWX generates HTML pages, but it does not update them <https://github.com/weewx/weewx/wiki/Troubleshooting-the-Davis-Vantage-station#weewx-generates-html-pages-but-it-does-not-update-them>* for details.
A corrupt database (as opposed to logger) is very unusual, although I guess it could happen. You did not provide enough of the log to be sure. In any case, to answer your question, yes, just swap in your backup database.
