That's not a problem in my thinking.
If you backup a lot of small files, your file table will grow a lot.
After your definied recycle time, old files will be deleted from the table.

If your "old" system has different backup rules or vm's the number of files is possible smaller and so the file table is smaller. This table is, from the numbers I can see, your biggest difference between old and new.

How long do you store backups before your overwrite the media files?
Have you done tests and these test data is still in the new system?
Have you compared backup jobs between old and new (number of backuped files)? Have you compared the job definitions, eventually you exclude some stuff in the old system? Same usage scenario of the vm's? We have a dev machine and a job creates a lot of temp and testfiles ... Do you backup the vm as file or do you backup the files from inside of the vm?

I would wait until the system gets to the point where it recycles volumes and look if you have a "stable" disk usage after this. A new system will grow at the beginning and your db size is not big. I mean 10G is nothing. Our backup system is small and the data dir is 20G in size.

I got a little confused when I wrote the server name. I meant that the database size of the old CT-BAREOS01 server, which is more than 2 years old, is larger than the new VL-BAREOS02 (1 month of use). CT-BAREOS01 has much more VMs backups than VL-BAREOS02, but the database size is smaller

    Hi Ramil,

    you wrote your old server has more backup files (files to backup in my
    mind).
    The size of the file table says something different.
    Have you done a simple count over the file table to look for the number
    of entries?
    Eventually you backuped more files as expected on the new system.
    -> a lot of small files will not grow the used media size but the
    filesize and the infos to store will be a lot more

    Best
