Backup jumps in size no matter what addon I select

Configuration
1

When performing a backup, my base backup is about 355MB but if I add any addon in the backup it jumps massively in size up to 10.4GB regardless of how many addons I select or even if I select the smallest one.

I have migrated from sql lite to maria DB, so I am aware I need to bring this with me in a backup but selecting anything balloons the size.

Any ideas?

Yeah, ignore that "estimated" size. I'm pretty sure that's a bug & almost certain I've seen either a forum post or a GitHub issue about it.

The only backup size you need to be concerned about is the actual file size after backing up.
