Server is unable to open backup server database

Hello,
My UrBackup server has stopped working. On checking the log files, I found the following:

After the default partition filled up faster than expected, I moved the database files to a different partition and created a symlink to them (using the command from this post ). This worked for a time, but I wanted to move them to an SSD. The files were inaccessible after I moved them to the SSD, so I had to use testdisk to copy them back to the original location.
I tested the symlink (i.e. cat /var/urbackup/server_token.key gave the correct key).
I am not sure why the server is unable to open the database file. I would greatly appreciate any help with diagnosing this or a suggestion if someone has encountered a similar error.

Issue was with file permissions within the database. Updating those permissions to allow more access solved the issue.

I’m having the same issue, however I’m not familiar enough with database permissions. How exactly did you correct the permissions?
