Since switching from Pop!_OS (Gnome) to Kubuntu (KDE) for work, I have also changed my backup GUI. There is no question that Vorta is more powerful than Pika Backup, but the price of that is the loss of simplicity.
One place I got confused was in the backup-retention rules, referred to as “pruning” by the GUI. I have learned: when Vorta offers to “keep all backups made within…”, that is internally a separate rule with high priority. Therefore, when I set up my hourly backups to keep “one week” of hourly, two weeks of daily, and so on, but “keep everything from the last six weeks,” I ended up with seven weeks of hourly backups, followed by the two weeks of daily.
I noticed the problem when my laptop fans spun up for a while, which turned out to be Vorta verifying 300+ archives. The work laptop is on only for work, producing backups for 8–9 hours per weekday, for around 250 extra archives over those first six weeks.
Unrelated, but one nice thing about Vorta is that, like Pika, it is a front-end to Borg. I gave it the same repository on disk. Now I have continuous backup history across the two GUIs, and emergency CLI access if necessary.
