Backup cannot start because free space is less than 25%

[toppse]

Hello together,

I want to make a backup to my mounting point...

The mount point is windows share with a disk space of 5,2 TB and 4,7TB are in use... so 500GB are free, thats enough for the zimbra backup.

So when i start the following command:
zmbackup -f -a all -t /mnt/backup/

I got the following message:
com.zimbra.common.service.ServiceException: system failure: Backup cannot start because free space is less than 25%
Caused by: com.zimbra.cs.backup.BackupServiceException: Not enough free space; path=/mnt/backup, total=5232661MB, free=501461MB

It is true that the space is less than 25%, but for me there is enough space for zimbra...

Could i change the value of 25% to 10% for example?

This is that what i need...

zmprov mcf zimbraBackupMinFreeSpace <value>
