Message "Not enough disk space" although there is enough disk space on external hard disk

[Michael Kohl]

Hello,

since three or four days I encounter the problem described in the summary.

1.
Description: Ubuntu 12.04.1 LTS

2.
deja-dup 22.0-0ubuntu2
duplicity 0.6.18-0ubuntu3

Similar problem description from other person on forum post with no answer, yet:
http://forum.ubuntuusers.de/topic/d-j-dup-zu-wenig-platz-bei-ubuntu-one/#post-4325492

I'm using an external hard disk via USB with still 1,3 TB of free disk space. The capacity is 2 TB altogether.

For several months daily backup was working fine. But now the backup starts but is not completed. Instead the message "Not enough disk space" appears.

The external drive is formatted: msdos

Checking the file
/tmp/deja-dup.gsettings

It contains:

org.gnome.DejaDup backend 'file'
# I tried to solve the problem by stepwise reducing minimum keeping time, it did not work
org.gnome.DejaDup delete-after 28
org.gnome.DejaDup exclude-list ['/home/userhome/.local/share/Trash']
org.gnome.DejaDup include-list ['/home/userhome']
org.gnome.DejaDup last-backup '2012-11-09T11:31:42.736356Z'
org.gnome.DejaDup last-restore ''

# in fact it is a USB-Harddisk with 2 TB
org.gnome.DejaDup.File short-name '8,2 GB-Dateisystem'
org.gnome.DejaDup.File type 'normal'
org.gnome.DejaDup.File uuid 'AF7D-EAE9'
org.gnome.DejaDup.Rackspace container 'computername'

org.gnome.DejaDup.S3 bucket ''
org.gnome.DejaDup.S3 folder 'computername'
org.gnome.DejaDup.S3 id ''
org.gnome.DejaDup.U1 folder '/deja-dup/computername'

So I thought, maybe there's some confusion about the storage type or path.
So I defined once more the backup-path with the USB-Drive online an tried to backup once more.

This backup failed, too.

Checking the new file
/tmp/deja-dup.gsettings
No difference compared to the first one.

The original message is in German:
Datensicherung fehlgeschlagen
Nicht genügend freier Speicherplatz

The file
 DEJA_DUP_DEBUG=1 deja-dup --backup | tail -n 1000 > /tmp/deja-dup.log
is attached but has been shortened.

Thank you.

Best regards

Michael

Reading bug # 1075171 I tried again after reboot, but the backup continues to fail.

[Michael Kohl (rolf-michael-kohl)]

After defining a new backup folder on the same USB-Drive, the backup is working properly again. But it started a completely new backup. My conclusion so far: the appearance of the problem described in the summary has probably something to do with folder size, number of files in a folder, processor power or thereabout.

Probably the message "Not enough disk space" appears because the cache directory of deja-dup - which can get very big - fills up your internal disk.

The cache directory is located in ~/.cache/deja-dup. Move this directory to your USB-Drive and create a symlink to workaround the problem e.g.:

mv ~/.cache/deja-dup /media/usbdrive
ln -s /media/usbdrive/deja-dup ~/.cache/deja-dup

Affects me too on 12.10 and did so on 12.04 LTS. Now I switched to using pure CLI duplicity, which works stable and fine. I hope I can switch back to the Déjà Dup GUI frontend some day, I liked it a lot! Best wishes, Michael
