Solved Problem with DB backup

[Matthieu Jacquart]

Hi,

I’ve got this problem since long time, so it’s not related to RC11 or RC10 : So each time I upgrade fog, FogDBBackup folder in /home only contains 1Kb files, whereas few months ago file size was the same that when I export database (between 2MB and 5MB).

And new problem since I move my older fog server (Debian 8 ) to new Debian 9, in Web UI “Fog configuration” - “Configuration save”, when I export database (user and passwor dare ok), there is blank screen (http://fog/fog/management/export.php?type=sql) and nothning happens…

Thanks
Matthieu

@sebastian-roth Hi,

I rebooted fog server and now I can save and export database, but it’s not the first time I had to do this on the new server to backup DB

root@FOG:~$ ls -al /tmp | head -5
total 68
drwxrwxrwt 17 root root 4096 janv. 30 08:55 .
drwxr-xr-x 25 root root 4096 janv. 30 08:12 ..
drwxrwxrwt  2 root root 4096 janv. 30 08:15 .font-unix
drwxrwxrwt  2 root root 4096 janv. 30 08:15 .ICE-unix

root@FOG:~$ ls -al /tmp/fog_backup_tmp.sql
ls: impossible d'accéder à '/tmp/fog_backup_tmp.sql': Aucun fichier ou dossier de ce type

and I launched install script before rebooting but once again sql file in /home/fogDBbackups is only 1KB

root@FOG:/home/fogDBbackups$ ls -l
total 12
drwxr-xr-x 2 root root 4096 janv. 30 08:12 .
drwxr-xr-x 6 root root 4096 janv. 30 08:12 ..
-rw-r--r-- 1 root root   25 janv. 30 08:12 fog_sql_1.5.0-RC-11_20180130_081251.sql

@Matthieu-Jacquart Please run ls -al /tmp | head -5 and ls -al /tmp/fog_backup_tmp.sql and post here.
