このファイルシステムにはかなりの空きスペース（およびinode）がありますが、十分なスペースがないrdiff-backupようです。だから現在のバックアップは動作しません。 :-(. なぜですか？
（これからこれを行うためにどれだけのスペースを確保するべきか疑問に思います！）
私のrdiff-backupバージョンはです1.2.8-7。私のオペレーティングシステムはDebian 9 "stretch"です。

Previous backup seems to have failed, regressing destination now.

でtmpfsを無効にする/tmpか、rdiff-backup十分なスペースがある他の一時ディレクトリを使用するように構成する必要があります。可能/var/tmp。
tmpfs 251M 4.0K 251M 1% /tmp
復元または元に戻す場合、rdiff-backup にはデフォルトの一時ディレクトリに空き領域が必要です。 Unixシステムでは通常/tmpディレクトリです。 rdiff-backup で使用される一時ディレクトリは、1.1.13 以降で使用可能な --tempdir オプションと --remote-tempdir オプションを使用して設定できます。デフォルトの一時ディレクトリの詳細については、Python一時ファイルのドキュメントのtempfile.tempdirエントリを参照してください。必要な空き容量の量はさまざまですが、通常は回復する最大のファイルのサイズに似ています。
--rdiff-バックアップFAQ：rdiff-backupには空き容量が必要な場所とスペースがどれくらい必要ですか？ rdiff-backupで「ValueError：生成されたデータ長が無効です」というメッセージが表示された場合、問題は何ですか？
