Backup_server_files.db-wal larger than expected

Server
1

Hi,
I’m trying out urbackup. I set up a server (debian bookworm) with a single client (win 10), both the latest version, and ran a single file backup.
There are about 34GB of data in 150k files and 25k folders on the client.
The server backs up to a NAS with lots of storage but the server itself only has limited storage.
Before the end of the first backup, I got this error:
Error in CQuery::Execute - database or disk is full
I checked /var/urbackup and found that
backup_server_files.db-wal had already grown to 1GB in size and used up all of the disk space.

Is this to be expected? I thought the database for 150k files should not be this large.

No opinions?
Would people like to share the size of their Backup_server_files.db-wal file so I get an idea what’s required, please?

Mine’s 350Mb off a new server backing up 17k files. So 1Gb does not seem surprising.
