Volume does not have enough free disk space to create VSS

[Hakujou]

Hi,

I'm trying to use Veeam Endpoint with a Backup & Replication server.
However, Endpoint throws me this error while I try to backup (file level backup) : "08/05/2016 11:04:50 :: Error: Volume DATA (D:) does not have enough free disk space to create VSS snapshot ".

The volume has 555GB free (it's a 1TB disk) so it's not a free disk space issue.

Is this some bug with the software or am I doing something wrong ? Thanks for your help !

Hello,

Can you please tell us where your VSS snapshots are pointed to? Does this drive have enough free space?

Thank you!

Thanks for your fast answer. Here's what I did (sorry, the output is in French, as I'm on a French Windows...) :

Take a look at Windows Event log for VSS related errors and try to create VSS snapshot manually. If you need an assistance with this, feel free to contact our support team directly.

Unfortunately, it seems that we can't create VSS Snapshots on Windows 10 using vssadmin...
Didn't saw any VSS related error on Windows Event Log, but I might have missed them.

[Vitaliy S.]

Once you're able to create a VSS snapshot manually, Veeam Endpoint Backup will also be able to run its backup job. Since this error above is referring to lack of free space, then try to re-direct VSS snapshot to some other volume and then run the backup job again.

[Hakujou]

I'm not sure if there's a way to trigger it manually via GUI/command line. All documentation I've seen is for Windows Server, not Windows 10.

This is definitely not a free space issue. The volume is not even half full...

[Vitaliy S.]

OK, let our support team take a look at your disk configuration via remote WebEx session.

[Hakujou]

I'm sorry, but as it's my own personal computer, I'd rather have a procedure or instructions than giving full remote access to it...

Hakujou,

Anyway, please open a support case and let the team check your logs and investigate the issue. Please do not forget to include the case Id to this thread. Thanks

Hi i have the same problem how do you fix this please ????. I have 800Gb free and it still gives me the same Error: Volume Data (D:) does not have enough free disk space to create VSS and there is more than enough space. Im using a Nas as the backup device which is 5.14TB free space as well.

SYSTEM user didn't had any rights on the drive. Adding them fixes the issue.

[Dima P.]

Thanks for sharing the solution!

Travis, did that help or you are still experiencing this issue?

[Travisehouston]

Thanks. I guess you have to open a case and ask our team to investigate the application logs. You can do that directly via VEB’s Control Panel > Support tab. Do not forget to post the case ID please.
