No recent feature. But keep in mind it's a system backup and afaik you have to restore the whole system when you intend to get back to the backed up savegames.
Like I said, not a good option but better than no option at all.
- Insert the USB into your PS5.
- Go to Settings > System.
- From there, System Software > Back Up and Restore > Back Up Your PS5.
- Select the drive you want to back up your data to.
- Check the box next to the data type you want to back up.
- Select next > Backup
Since I have old HDDs lying around here anyway, it wouldn't make sense not to back up the system from time to time. Speaking of which, backing up right now.
