Thank you for your reply! Indeed, the underlying OS needs to understand the thin provisioning from VMware. VMFS does this, but NFS/CIFS not. I am trying to SCP/RSYNC my backup to the cloud, but then i have to upload the whole size of the disk. I tried the backup with "--backup-prog=xsitools" and then i get the provisioned size and not the whole disksize as backup. The only 'but' is that i need the PRO version to restore my backup.

Is there any other way i can use XSIbackup to backup my provisioned size from my datastore without using an VMFS disk as destination or using XSItools? I want to store an copy in the cloud, and i can only mount my cloud drive through WebDAV/NFS/CIFS.

Maybe it has something to do with my datastore? I am using VMFS6 as my datastore. I tried to use an NFS datastore, but the same thing happens. When i create a blank VM, the used space is 0MB, but when i access the storage (not via VMware Datastore Browser, but i just mount the NFS storage) i see the size on my disk is the actual size of the HDD i attached to the new VM (so for example the disk is 16GB, even though it is using 1MB). When i backup the VM, i backup the whole 16GB.

See picture for example:

Anyone experiencing the same issue? (Or maybe its not an issue but just the way VMware works with storage?)

Hello,

I am using xsibackup to backup my VM's. This is the command i use to backup:

"/vmfs/volumes/datastore/xsi-dir/xsibackup --backup-point=/vmfs/volumes/datastore/VM-BACKUP --backup-type=all --backup-prog=vmkfstools"

I am using THIN provision on my VM's. So lets say if i added a 100GB HDD and it is using only 20GB, in VMware i see used space: 20GB. But when i do the backup, the whole 100GB HDD disk gets backupped. When i check the disk properties, i see that it is using 100GB om my backup destination.

Is there any way i can only backup the size that i actually used in stead of the whole 100GB?

Thanks in advance.
