"There is enough space to backup" on new DS3622XS+ and DVA3221 (v0.9.4.9c)

[MrHappy]

Describe the bug When trying to do a fullupgrade through the webui I get

Performing a full TCRP upgrade
Backuping up current files to /mnt/sda3/backup/loaderbackup-2023-Jul-26-15-23.tgz
tar: Removing leading `/' from member names
Backing up loader and making current home dir persistent

There is enough space to backup

Backup File Date : Jul 26 15:23

Backup File size is : 39M

Through commandline it does seem to work.

To Reproduce Download image and create a new vm (in my case on Proxmox)

Expected behavior To be able to use the fullupgrade through the webui.
