I have quite a lot of free space (and inodes) on this filesystem, but rdiff-backup apparently runs out of space. And hence my backups are not working at the moment :-(. Why?

(I wonder how much space I should be reserving for this in future!)

My rdiff-backup is version 1.2.8-7. My OS is Debian 9 "stretch".

IOError: [Errno 28] No space left on device

You need to either disable tmpfs on /tmp, or configure rdiff-backup to use some other temporary directory which has enough space. Possibly /var/tmp.

tmpfs                           251M  4.0K  251M   1% /tmp

When restoring or regressing, rdiff-backup needs free space in the default temp directory. Under unix systems this is usually the /tmp directory. The temp directory that rdiff-backup uses can be set using the --tempdir and --remote-tempdir options available in versions 1.1.13 and newer. See the entry for tempfile.tempdir in the Python tempfile docs for more information on the default temp directory. The amount of free space required can vary, but it usually about the size of the largest file being restored.
