restored backup larger

[Halfhidden]

Hey guys I wonder if anyone has had this issue before. I backed up an instance of Nextcloud (CT) and restored it through PBS but the difference in data size is astonishing.
The restored Nextcloud reports that it is using 32gb, which I believe is a fair account for the amount of data that is within it. However the restored image in the CT volumes says that it is 536gb
What has happened, is there a way to reduce this size, is it white space?

Really depends on the storge you restored it to. How does your /etc/pve/storage.cfg looks like? Does it support thin provisioning?

This is pretty much it I think:

ir: local
        path /var/lib/vz
        content backup,vztmpl,iso

lvmthin: local-lvm
        thinpool data
        vgname pve
        content rootdir,images

pbs: BackUp1
        datastore BackUp1
        server 192.168.1.23
        content backup
        fingerprint xxxxxxxx
