Finding out the reason for the failed backup

Hello,

With the planned backup, a backup of the database was created, but unfortunately, the backup of the files could not be created. I then ran the backup manually but got the error again.

How can I find out the reason for this, is a detailed log kept for this?



Thank you.

 

you should be able to use this script to run a backup manually from the cli.
/usr/local/ispconfig/server/lib/classes/cron.d/500-backup.inc.php
it's been a long time since i've used it, i can't remember if it needs any arguments or not.

or /usr/local/ispconfig/server/backup-now.php
Usage:
php backup-now.php --id=<4> [--type=<all>]
Options:
--id id of the website to backup.
--type backup type: all, web or mysql. Default is all.

 

Thank you for your time, I did as you mentioned, below is the console result. Do you think there could be a problem as stated in this question?

Code:

root@serve:~# php /usr/local/ispconfig/server/backup-now.php --id=2
Making backup of website id=2, type=all, please wait...
zip warning: No such device or address
zip warning: No such device or address
07.01.2022-19:08 - ERROR - Backup of web files for domain example.com failed using path /var/www/clients/client2/web2 failed.
All operations finished, status success.
root@serve:~#

 

unless you've changed the backup script then i doubt it's the same issue. the default script works on too many other systems to be something like that, plus i would expect the db backup to have the same problem.

what OS is it? version?
is it a single server or multi-server ispconfig?
if multi-server, are the databases and websites on the same server?
have you changed the backup folders from the default /var/backup?
is the backup folder on the same disk as the web files? the db files? is it a local mount? a remote mount?

maybe you can look through /usr/local/ispconfig/server/lib/classes/backup.inc.php and find out exactly what command is being run to execute the web files backup and try running that manually from the cli, that might show more details about what's going wrong.

 

or do what @Jesse Norell says. would be easier. dunno why, i always completely forget about ispconfig's debug mode setting.

 

Debian 10
Single server
No, I didn't change the backup folder
Yes, the same disk

There is no problem in backing up 3-5 GB websites, but some sites use 15 GB or more. The temporary ZIP file, where backups of websites using high GB space are created, usually reaches 11-12 GB, and the backup process results in an error. There is no problem with small-sized sites. I think it's a problem in backing up large sites.

 

Several large sites were backed up without any problems. I downloaded the backups to my computer and opened it, everything is flawless. I thank you and other valuable people for your interest.
