[Server-devel] Backup and Recovery

[Hamilton Chua]

Martin,

Thanks so much for the replies.  I have found the problem. I was
creating the spins based on the strawberry release. It seems there were
a few changes in the journalentrybundle python script since then that
allows restore to work.

I have backported the changes to the strawberry release and restore
seems to be working now. 

However, I would like to ask how the work flow goes for restoring data.

Here's how I do it :

1) boot SoaS
2) open the Browse Activity and go to the "Backups" tab in my moodle
page
3) click on the link of a backup I want to restore
4) Browse downloads the file and puts it in the Journal
5) I click "Show in Journal"
6) I see the "Activity+Backup" file details.
7) Click "back" to journal

Now in the Journal, right below the "Activity+Backup" file entry in the,
I see the data that was restored.

Is the above how more or less restore should work or behave ? I was sort
of expecting the  "Activity+Backup" file to be replaced by the restored
data in the Journal.

Thanks again.

Best,

Hamilton
