Hello All,
since some time we issue some problem with poor efficiency on Windows Machines backups. The linux guests backup with performance level of 5GB/min and above - generally 7GB/min to 15GB/min, when Windows don't go abowe 700MB/min, and it's max that we can get. Mainly there is 100MB/min, or even less.
The configuration is like this The VDR is in HA cluster with 5 hosts and something about 82 machines, but not all of them are backed up.
The VDR is a linux machine - CentOS with two attached SCSI disks that reside on the same Datastore. One is !TB for Linux machines backup that one performs perfectly, the second one is 1,5TB and is used by the windows machines backups.
I'm wondering what could it be that the VM's with Windows are performing so poor? Is it the problem that the size is not the recommended by this KB:
Configuration
Q: VDP comes in 3 different OVA sizes: 0.5 TB, 1 TB, and 2 TB. Why is this, and is this all the space I need for the appliance?
VDP comes preconfigured with the destination datastores already attached. The OVA sizes indicate the size of the destination datastore. Additional space is required for the operating system and VDP operations (checkpoints, logs, etc). The amount of disk space required is:
| OVA Size |
Disk Space Required |
| 0.5 TB |
850 GB |
| 1 TB |
1600 GB (1.57 TB) |
| 2 TB |
3100 GB (3.02 TB) |
Notes:
- In VDP 5.5 one OVA size is available, you will be prompted to choose the size of your deduplication store during configuration.
- When a VDP appliance is deployed, additional space cannot be added to an existing appliance. If more destination datastore capacity is needed, a new VDP appliance can be deployed (up to 10 appliances can be deployed per vCenter Server).
- When sizing a datastore to house a VDP appliance, consider if the virtual machine swap file will also reside here and allocate sufficient space.
