RSSRadio7 keeps all its information in a database. This information can be quite precious if you have more than a couple of subscriptions:
- RSSRadio settings
- Listened / Unlistened state for your Podcasts
- Show metadata which may not still be available in the Podcast feed
I recommend backing up this data to Dropbox.
To ensure your latest show listened state and subscription settings are continuously backed up you can turn on the sync. I previously wouldn't recommend this with iCloud syncing as iCloud is not that reliable but now Dropbox is supported its well worth everyone having this switched on.
