Backup failed, getting space error

when I started the backup process from Panel, I deleted previous backups and more than 120 Gb was available but after sometime storage will be full by the backup folder, why were backups taking that much size, I know didn’t store data more than 50 GB (all users), before updates this issue has never happened

Delete all the existing tmp.* folders

I Tried but not working
( Temp folder size is in kb)

Can i delete entire backup folder and try with backup again from gui panel

i delete a backup folder, now Trying to backup from begin from GUI panel

Q. 1) suggest the best configuration

Q. 2) what i have to mention here?

I don’t know how you have set it

I can’t debug rclone end points…
