Hi and welcome to Qlik Fix.
This video will demonstrate how to restore the Qlik Sense Repository database or QRS from a backup.
First, verify that only the Qlik Sense Repository database service is running on the machine.
The existing database will need to be removed prior to restoring the QRS backup.
This can be done using PG Admin – a standard database utility.
Open up PG Admin
Create a connection to the server machine hosting the Qlik Sense Repository database.
Port 4432
Postgres user and password.
Here you can see all of the tables where Qlik Sense stores data in the current database that will be dropped.
In PG Admin you could do this with the Delete/Drop option.
I’ll be using these commands copied from the Qlik help site.
Open a command prompt with Administrator privileges from the PostgreSQL 9.6 bin folder.
Copy and paste in the command
Connecting locally,
On port 4432
With the postgres user defined while installing
And dropping the current QSR database.
No other tasks should be running in parallel, so I’ll disconnect PG Admin.
Enter the password
And back to PG Admin to verify that the database has been removed.
You can see that QSR is gone.
Now, copy the Create DataBase command from the Documentation.
The Template0 will create a basic schema, but there will be no tables.
Copy
Paste and run the command
Done.
Back to PG Admin to illustrate.
The QSR has been created with a public schema, but with no tables.
Now we’re finally to the step of restoring from the backup.
This could be done in PG Admin via the Restore command,
Point to the backup tarball, hit restore,
But again, this is a demo of the manual method.
Copy the restore command.
You can see a variable here to the path to the backup file
Copy everything up to that point
Navigate to the QSR backup on an accessible shared drive folder.
Copy the backup locally.
This folder has been created on the local C drive called QSRBackup
An easy way to get the file path is to press Shift and right click,
then select “Copy as path”
Paste it at the end of the command
I recommend adding a “-V” to the command line so that you can actually see some more verbosity to what is happening.
Again, close any tasks or open connections to the database.
Enter the password
And there it goes.
To verify that the data is actually there,
Back to PG Admin one more time.
In the QSR database under tables, now there is all the content.
The QSR has been fully restored.
I hope this helped.
