Public bug reported:
I tried to restore my deja-dup backup after a new install migrating from
14.04.x to 16.04.01. I choose to make a fresh install because need to
encrypt data. Because of known bugs with encrypted swap I use the option
to encrypte the user-directory.
Because of a problem with a big files (bug report may follow) at the end
of the backup I had to restore directories by choosing "set back to an
earlier version" (retranslation from german "Auf frühere Version
zurücksetzen") for one dirctory after another.
After a big directory (ca. 70 GB) deja-dup ends the restoring process
with an error message. Deja-dup can not restore some files because of
the long path/filename.
Here are two examples from the list with 28 files:
'/MATERIAL/PHYSIK NAWI/Überblick zur DVD Relativitätstheorie und
Gravitationswellen. Spannende Filme über eine 100 Jahre alte Theorie und
ihre höchst aktuellen Anwendungen.pdf'
'/FALDERA/12-Physik/12.2 Quantenphysik des Lichts/04 --
Lichtelektrischer Effekt/Albert Einstein: Über einen die Erzeugung und
Verwandlung des Lichtes betreffenden heuristischen Gesichtspunkt. In:
Annalen der Physik. 322, Nr. 6, 1905 -- 1905_17_132-148.pdf'
Because restoring my backups to an unencrypted home directory worked
before, it could be related to the encrypted user-directory.
Thanks for all effort and
kindest regards
