THX, works! But, the dialog window on the command line did not find/display the tar file. I had to enter the file name manually.

Hmm yes. Old versions created a .tar file. Newer version create .tar.gz files (i.e., the backup is gzipped). The file filter only shows .tar.gz. Since there is a workaround to support very old backups (multiple years old), I'll leave it as is 🙂 Kind regards, Martijn Brinkers > **···** > > On 05/06/2017 08:21 PM, Stefan Michael Guenther via Users wrote: > > > -----Ursprüngliche Nachricht----- > > > > > Von:Martijn Brinkers via Users \ > > > Gesendet: Sam 6 Mai 2017 19:53 > > > An: users(a)lists.djigzo.com > > > Betreff: Re: Restoring a backup from an old system fails: backup file to large > > > > > > On 05/06/2017 07:49 PM, Stefan Günther via Users wrote: > > > > > > > Hello, > > > > > > > > one of our clients is running a six year old Djigzo 2.3.1-7 (tar installation) > > > > > > > > The backup creates a nice 58 MB tar backup file. > > > > > > > > But when we try to import the backup on a 3.2.7-5, (virtual appliance) we get the error message "Restore failed.
