[Duplicity-talk] Out of space error while restoring a file

[Laurynas Biveinis]

Hello -

I'm trying to restore a ~30GB file from backups. The free space on the
drive is about 80GB. Yet on restore I get the error below. What would
be causing this and how much free space do I actually need to restore?

$ duplicity -t2D --file-to-restore "path/to/file"
--s3-european-buckets --s3-use-new-style s3+http://foo $HOME/file
Local and Remote metadata are synchronized, no sync needed.
