Wrong error message "Backup location is too small"

[Tom]

When trying to back-up to a mounted harddrive (nfs), this message is being displayed, although the backup volume is less than 20 GB with >1.5 TB available at the remote harddrive. Backup terminated at this stage.
Although this bug has been reported before and also seemd to be fixed now, it is back (?) now.
Tried Déjà Dup versions 20.1 and 22.0 on Ubuntu 11.10 (duplicity 0.6.15). Also, removing Shared Memory (according to https://help.ubuntu.com/community/StricterDefaults) did not solve the problem

Sounds like gvfs isn't being honest about the size of an nfs filesystem... Additionally, Deja Dup and nfs don't get along super well (Deja Dup doesn't notice when nfs filesystems go away or appear).

It does have special support for pluggable (non-nfs) hard drives, if that's just as easy for you to use...

Can you give me the output of:
gvfs-info -f /path/to/backup

Similar (or same) problem here.

Using version 34.2-0ubuntu1, on Ubuntu 16.04, backuping to a webdav location (so, 'file' backend) that is supposed to have 18.4 EB (!) of free space. The output of 'gvfs-info -f /path/to/backup' is:
---
attributes:
  filesystem::size: 27024223262
  filesystem::free: 18446744073709551613
  filesystem::type: webdav
  filesystem::used: 27024223265
  gvfs::backend: dav

Duplicity runs without problem with the same include-, exclude-lists, and same backup location.

Same problem using webdav here. gvfs-info:
gvfs-info -f davs://rkupper.no-ip.org:444/remote.php/webdav/backups2
Attribute:
  filesystem::size: 7814
  filesystem::free: 18446744073709551613
  filesystem::type: webdav
  filesystem::used: 7817
  gvfs::backend: dav

This was fixed in gvfs by https://bugzilla.gnome.org/show_bug.cgi?id=786177 and in deja-dup by https://gitlab.gnome.org/World/deja-dup/-/commit/700d828125fa6b0e769ca3abf657b15cc2997715
