Best configuration:Local-Cloud using WAN-Accelerators

[MatthiasR]

Hi guys,

I just have an question for the "best" configuration for my scenario.
At this momemt I have an 7 TB local backup, but on my cloud storage the backups take over 10 TB disk space.
So my backup-copy jobs fail with the message "There is not enough space on the disk".

I think there is a misconfiguration on my side, so maybe somone can help me.

At this momemt I have the following set up:
My local Veeam Server backup all selected virtual machines on his local repository.
With the backup-copy job, I transfer all vm´s to a local USB drive.
With another copy-job, all vm´s were transfered to the cloud storage (I created 6 jobs and split the vm´s on them, so not all VM´s were saved over just one job).
Here I use the WAN-Accelerator setting, so that my cloud Veeam Server, can merge backups "in cloud" and save them to the cloud repository (for my cloud server this is his local storage)

Local:
Veeam Server "Veeam-Local" with Veeam B&R 9.5 (Enterprise Plus Edition)
- Backup Repository: "LOCAL" Local hard disks with RAID 5
- Backup Repository: "USB" Local USB-Drive
- Backup Repository: "Cloud" - 10 TB Storage
- WAN-Accelerator activated

Cloud:
Veeam Server "Veeam-Cloud" with Veeam B&R 9.5 (Enterprise Plus Edition)
- Backup Repository: "Cloud" - 10 TB Storage
- WAN-Accelerator activated

Backup Jobs (Type: Hyper-V Backup):
Specified virtual machines from the two local Hyper-V Server.
Backup mode: Reverse incremental
To Backup Repository "LOCAL"

Backup Copy Jobs:
All virtual machines are copied to Backup Repository "USB" (in settings I configured the Backup Repository "LOCAL" as source)
All virtual machines are copied over WAN-Accelerator to Backup Repository "Cloud"

Why is my cloud backup 2 TB bigger then my local?
I think my main fault is the "reversed incrementel".

Would it help to change these settings to "incrementel"?
If so, periodically full backup or synthetic full backup?!

Hopefully somone can help me.

Kind reagards,

Matthias
