[informant]

Hi, we have change the size in vzdump.conf to 4096, but we get on Backup the error message

Log is very long and doesn´t show complete in log-window.

The ct have in Backuptime max 200mb new data create, why we get the error with size 4096? Do you have a information or a fix for us please?

Very thanks.

regards

If the number or the size of the files inside the container is too big, you can run into this issue.

Try increasing the size of the temporary lvm snapshot. Edit size value in /etc/vzdump.conf. Make sure first that you have enough free space on /dev/pve (check with pvscan).
