    Hi,

    Assuming I've got a NFS server/share in place and the relevant entry under fstab to be auto-mounted under /var/backup.
    What does the option "Backup directory is a mount?" has to do with the above? Does it check if is mounted and if not it tries via the fstab entry?
    I've read some old posts about it but wasn't clear about its behavior.

    Thanks

    From the manual: "Enable this option when the backup directory needs to be mounted before the backup starts. ISPConfig will then run the shell script
    /usr/local/ispconfig/server/scripts/backup_dir_mount.sh before it starts the backup process. Create that script and add the required mount commands to it. Ensure that the script is exacutable!"

    All functions are described in the manual, you can get it for a small price by becoming a HTF member or through a one time payment: https://www.howtoforge.com/download-the-ispconfig-3-manual

    Thanks Thom, I bought the manual but somehow missed that.

    By the way how to umount afterwards the directory when the backup finishes?

    You could alter the backup script for this, but there is no build in function afaik.

    So actually what it does is just to check if is mounted in order to avoid writing the files to the local file system. What about if the mount fail, let's say when the remote backup server is down. Does it stops & throws an error or it starts writing to the filesystem?

    Just checked the code, a error email should be sent out.

    Where is stored the relevant log file to see why the backup mount isn't created properly.
    I've test the mount by running my /usr/local/ispconfig/server/scripts/backup_dir_mount.sh and worked fine. Then I run a manual backup and nothing is happening; no backup, no mount.

    As far as I can see in the code the errors are sent to you by email. But the script is not run before you do a backup, it's run by the system if you enable the function.

    If the mount is working, there is probably a different issue. Have you checked all settings for the backup?

    Even if I mount the remote storage manually and then run a manual backup of DB nothing is happening. Backup of DBs are not happening at all.
    On my web1 server (I've got multiple web/db servers) under:
    /usr/local/ispconfig/server/lib/mysql_clientdb.conf
    it has the localhost mysql settings.
    Should I put there the remote db server as well?
    If yes, I have to put more than 1. How is the proper syntax for that?
    At the moment it has:

    Code:
    [email protected]:~# cat /usr/local/ispconfig/server/lib/mysql_clientdb.conf
    <?php
    
    $clientdb_host            = 'localhost';
    $clientdb_user            = 'root';
    $clientdb_password        = 'mypass';

    It doesn't help much; here is the output:

    Code:
    [email protected]:~# /usr/local/ispconfig/server/server.sh
    24.10.2020-23:50 - DEBUG - Remove Lock: /usr/local/ispconfig/server/temp/.ispconfig_lock
    finished server.php.
    [email protected]:~# ls -la /usr/local/ispconfig/server/temp/.ispconfig_lock
    ls: cannot access '/usr/local/ispconfig/server/temp/.ispconfig_lock': No such file or directory

    Just tested it here, works fine for me.

    Are you making a backup of your database or web files? if database, is there a database connected to that web? Which folder are you checking for the backup? It should be in /var/backup/webID (replace ID with the web ID)

    Here is my setup:
    server1 - controlpanel
    server2 - web
    server3 - web
    server4 - db
    server5 - db
    etc
    Web files are backing up correct, no problems at all. It is only the DB backups that don't work; no errors and no files are creating either under /var/backup.
    The directory /var/backup on the DB servers is empty.

    Have you tried running it when /var/backup is not a mount?

    This is very bizarre. Yes, I just tried without been mounted and nothing is happening; no error, no email, no DB backup.

    Further to my post, even from cli it doesn't work.
    php /usr/local/ispconfig/server/cron_debug.php --cronjob=500-backup.inc.php

    Does not show anything just "finished" but, in the backup list on user panel I just see the web files not any DB backups.

    That's weird. Where did you do the debugging? You should do this on the DB server, not the panel or webserver.

    That's normal, as it is queued when you click make manual backup. When running the cronjob, it will just run the items from the queue.

    I confirm that I run the debugging within the db server. I did also a manual back from the mysqldump just to double-check that I can write to the remote storage and all was ok.
    It just doesn't work through the GUI.
