Hi there!
Yes, that’s intended. The original tables, before 3.0.x, were wp_popularpostsdata (All-time) and wp_popularpostsdatacache (last 24 hours, last 7 days, etc). The wp_popularpostssummary table was added on 3.0.0, and all data in wp_popularpostsdatacache was transferred to it.
After the migration process, the wp_popularpostsdatacache was renamed to wp_popularpostsdatacache_backup to keep a “backup” of users data, just in case anyone decides to downgrade to an older version of the plugin. I’m planning to have wp_popularpostsdatacache_backup removed automatically on a future upgrade, though.
Ciao Hector,
I’m cleaning-up my DB and saw wp_popularpostsdatacache_backup which is using 372.2 Kib which is easily one of the top three largest tables.
Can I safely drop it out of the DB manually without creating any problems for my current (and most up-to-date) Popular Posts installation?
Ciao,

Hi there!
Yep, you can delete that table safely.
