Backup to 10TB drive says Low Free Disk Space at 1TB free

[AlexLeadingEdge]

Hi guys,

Not a big issue but we installed some internal 10TB drives for the initial backups before we do backup copies to various daily-rotated USB drives and offsite places. Everything was going great but now we are seeing Low Free Disk Space warnings, which I assume is because the free disk space is under 10%. It has plenty of space to do its backups, is there a way to remove this warning so we don't get notifications and emails saying something is wrong?

11/12/2019 8:02:29 AM :: Backup location [H:\VeeamBackup\] is getting low on free disk space (842.1 GB free of 9.1 TB)

Hi Alex,

You can add the following key to the agent machine and set value to 1 (1%)

Code: Select all

HKLM\Software\Veeam\Veeam Endpoint Backup\
DWORD
BackupRepositoryFreeSpaceThresholdPercent

Will that work for your environment? Thanks!

Hi Dima, I have set the value to 5, and this has fixed the issue. Thank you!

Same issue again today. The registry key changed to '5' has fixed the issue once again

years later i also had to change / add the key - would it possible to implement that the agent get this value from backup server in case of central management?

I use the Veeam agent for Windows under Windows Server 2016. The registry key
HKLM\Software\Veeam\Veeam Endpoint Backup\
DWORD
BackupRepositoryFreeSpaceThresholdPercent
unfortunately does not work here. What should the entry be for Windows Server 2016?

Hello Stephan65,

This key can be applied to any operating system (it's platform independent). Can you please doublecheck the registry path and key name to be correct, make sure that the value is set as well and restart the machine (the key is applied after Veeam Agent for Windows services are restarted). Thank you!
