Ok, purged the volume of the incremental job and ran the inc. backup
again.

All the information about the job tells me that 3 files and a directory were
backed up. But the size of the backup (4,478,194,813 bytes) does not fit then.

I find it hard to check if accurate backups are working as they should.
Especially the bls output below is confusing...
