File Backup Doesn't work on Windows Client / Ubuntu UrBackup server

Hello Folks,

I have UrBackup Server installed Ubuntu
urbackup-server/xenial,now 2.2.11.2193-1ubuntu1~xenial amd64 [installed]

I have Urbackup windows client 2.2.6 installed on Windows Server 2012 R2.

While the image level backup works on windows client for disk (both incr & full)
The file backup fails to start…
Any help I can get on this is very much appreciated.

On the client, after enabling debugging, I see this messages -
I am attempting to do a full file backup on “C:\OS Images” which contains a few text files.

What storage are you using as the backup store ?

For some reason the server cannot create files like /var/urbackup/clientlist_b_123.ub. Check permissions, free space etc…

@uroni, thank you so much, the file permission on the directory was not correct. This was not due to default installation outcome but rather due to directories being mapped against different zfs datasets manually after installation.

P.S - Thank you for developing this product, UrBackup + Zfs is a wonderful solution for medium sized businesses.

@dewitpj, the backend storage is zfs, the issue appeared to be a file permission issue on the server which @uroni correctly pointed out.
