No permission for backup + where to unzip it on the server?
Hi guys, Yesterday I installed updates for all my plugins + Magento itself (1.7 > 188.8.131.52). Afterwards some of my old ones didn't work correctly so I wanted to restore a backup I made before (system). I was told I had no permission to do so, so I tried to reinstall updates which appeared to be a bad decision as instead of bad-looking website I got an error "Service Temporarily Unavailable". The only thing that works is mysite.com/downloader but I got no idea where can I go from there.
On the other hand I have a systembackup.tgz but no clue where to unzip it, I bet it should be in the folder where I have following ones?
app, errors, js, lib, media, shell, skin, var
Should I now but my backup file there, create in the same folder a systembackuprestore.php file:
