Thanks,
I tried the commands, and the "du" reports a smaller size:
BUPNAS02> ls -l -h "/volume1/esxbackup/ALM Report Server"
-rw-------    1 admin    users     250.0G Oct 14 15:56 ALM Report Server-flat.vmdk
-rw-------    1 admin    users       8.5K Oct 14 15:47 ALM Report Server.nvram
-rw-------    1 admin    users        584 Oct 14 15:56 ALM Report Server.vmdk
-rw-r--r--    1 admin    users       2.5K Oct 14 15:47 ALM Report Server.vmsd
-rw-r--r--    1 admin    users       3.2K Oct 14 15:56 ALM Report Server.vmx
-rw-------    1 admin    users       3.1K Oct 14 15:47 ALM Report Server.vmxf
BUPNAS02> du -h "/volume1/esxbackup/ALM Report Server/ALM Report Server-flat.vmdk"
13.2G   /volume1/esxbackup/ALM Report Server/ALM Report Server-flat.vmdk

For that NAS I am not able to Mount to it another way because it is an older model.

----- Edit
I investigated further.
As you mentioned, it looks like a reporting issue. The actual size is really what "du" reports and not what the "ls" reports.

Thanks for your reply, but that syntax seems not to Work on a Synology NAS.
I ran the "ls" command instead:

BUPNAS02> ls -l -h
-rw-------    1 admin    users     250.0G Oct 14 15:56 ALM Report Server-flat.vmdk
-rw-------    1 admin    users       8.5K Oct 14 15:47 ALM Report Server.nvram
-rw-------    1 admin    users        584 Oct 14 15:56 ALM Report Server.vmdk
-rw-r--r--    1 admin    users       2.5K Oct 14 15:47 ALM Report Server.vmsd
-rw-r--r--    1 admin    users       3.2K Oct 14 15:56 ALM Report Server.vmx
-rw-------    1 admin    users       3.1K Oct 14 15:47 ALM Report Server.vmxf

and you can see the file "ALM Report Server-flat.vmdk" is reported as 250GByte instead of the actual size of about 18 GByte.

I have just installed the XSIBackup FREE and have made a few backups of some of my VMs.
All the VMs have Thin provisioned disks, so for example one has a disk set up as 250 GByte but actually uses 18 Gbyte of space in ESXi.
When XSIBackup makes the backup, it creates the *.vmdk disk as 250 GByte in size.
Am I using a wrong option when backup up?
The VM is shut down when I do the backup. The command to backup is:
/vmfs/volumes/part1/xsi-dir/xsibackup --backup-point=/vmfs/volumes/esxbackup --backup-type=custom ---backup-vms="Win10"

--- Edit

I have just noticed that when I browse the backup with the Datastore Browser from ESXi, then it shows approx. the same size as on the ESXi server.

Also, just for completeness, the backup point is a shared directory on a Synology NAS that has been mounted as NFS.
