[ovirt-users] backup.sh fails

[Niklas Fondberg]

Hi all,
I might be of a tangent but I tried to follow the steps in
http://www.ovirt.org/User_talk:Stkeimond/Backing_Up_And_Restoring_OVirt
for a backup.
I get an error because of the postgres user password that I never set in
the installation of oVirt (as far as I know.)
Does anyone know of another way to backup or is this a bug/fault_by_me?
The command line and error is:

[root at dl380 dbscripts]# ./backup.sh -u postgres -l /mnt/msa60/backups/
Backup of database engine to
/mnt/msa60/backups//engine_Mon_Jul_14_16:50:45_CEST_2014.sql started...
