cannot restore backup when mail app is included, fails relating to permission denied despite backup being chown'd by yellowtent

[CadeHenschen]

I'm trying to restore from a backup I've stored in a mountpoint on my DigitalOcean droplet. The following configurations begin a restore, get through the box portion, but then lulls on the mail restore (saying like 'Download 10M@1Mbps', despite being on the same machine). Once the restore fails, I get this message at the top of my restore screen:

Once I get to this screen and try to restore with the backup again, it tells me to remake the server.

Is this happening midway and has there already been some data restored at /home/yellowtent/boxdata/mail/... or is this the first file which fails there?

Also what are the permissions and owner for /home/yellowtent/boxdata/ ?
