Hello, we have a problem. When trying to make a backup for a client, we encounter this error:"Backup of VM 314 failed - command 'lxc-usernsexec -m u:0:100000:65536 -m g:0:100000:65536 -- /usr/bin/proxmox-backup-client backup '--crypt-mode=none' pct.conf:/var/tmp/vzdumptmp1643343_314/etc/vzdump/pct.conf fw.conf:/var/tmp/vzdumptmp1643343_314/etc/vzdump/pct.fw root.pxar:/var/tmp/vzdumptmp1643343_314 --include-dev /var/tmp/vzdumptmp1643343_314/. --skip-lost-and-found '--exclude=/tmp/?'

How can we solve this?
 
please post the full task log and "pveversion -v"

Code: 
INFO: Error: error at "var/www/html/pub/media/captcha/base": exceeded allowed number of file entries (> 1048576)

your container has a very high file count in that dir -> you need to bump "pbs-entries-max" in the performance key in /etc/vzdump.conf
 
Good evening team, I'm having a problem with the backup. Can you please give me some hints? Here is the error message :

1*:

Hi,
this error seems unrelated to the issue described in this thread (error code 2 might indicate fatal error), please double check your storage, i deduce from the name that this might be a NFS share). Please share your pveversion -v as well as the full task log for the backup job.

Edit: updated error code interpretation

Hello,
Thank you for your feedback. Here is the information you requested.

However, I found a solution yesterday by modifying the vzdum.conf file and adding the path tmpdir: /var/lib/vz/dump
