Backup not working on ispconfig 3.1.3 and 3.1.4

Hi,

I've everything installed

root@machine:/www/backup/web9# zip

How can i enable logging in /var/log/ispconfig/ispconfig.log?
Or is this not for that purpose? Where can i find error logs related to config errors like this backup problem...etc?

 

Do you mean debug mode? That is explained here:

I've solved it.

Backup tmp directory must exists in the system....

 

ON Debian systems upgraded 8 > 9 ... or updated:
In some cases problems with MYSQL backup on upgraded systems are caused by too high PHP version (7.3)... so first of all check:
update-alternatives --config php
Than do:
mysql_upgrade -u root -p
In some cases deleting old MYSQL backups helps... for now I got several VPS and only upgraded were affected still fighting with one VPS...

There are also problems with backup policy. In my opinion there should be some sort of settings to:
1) split backup i.e. WWW -> weekly (1 backup) MYSQL --> daily (3 backups). In most cases WWW is not changing as fast... MYSQL is more valuable.
2) on mounted NFS/SSH there should be option not to CHOWN
3) also in cluster mode / multiserver some sort of log (error/warining) to see if there is a problem with backup. Now You dont know if there is no backup for MYSQL unless You check manually.
4) lots of messages with mounted NFS backup:

Code:

Backup directory /var/backup could not be unmounted.
The command
/usr/local/ispconfig/server/scripts/backup_dir_umount.sh
failed.

I tried to delay umount. But I got this message even on new dedicated servers with no load and with small backup... I got this message randomly from different servers...
5) I noticed that regardless of the settings, mail backup is performed on the server at midnight. Now i got high overload... i would like to split jobs and have possibility to setup HOUR/SERVICE per server.

MY settings are latest ISPCONFIG 3.1.3/4 and mostly Debian 9 (updated daily).

 

It would be great if i change something in GUI it should be done at the machine (or at least get a proper error msg).

This case was hard, because ispconfig did not told me anything about why it has not createing backup.
