Partition_1 folder keep appearing in external back up mode

[hihi2u2]

Hi there,

I have a lot of photos on my external hard drive and I want to make a workflow

1. Transfer photos from SD card into external hard drive
2. Back-up external hard drive as incremental back up onto Asustor

I've tried the External Backup mode on ADM, it works, but it keeps creating a 'Partition_1' folder inside the folder I want to back up in.
Any idea how to back up the photos directly into the folder I want it to be backed up in without the 'Partition_1' folder?

Thanks

Have you tried to enable "Use 1 on 1 folder synchronization" when you created a backup job?
