Hi Guys,
i'm looking for some advice please.
We have 2 x host servers (A+B).
Both hosts have 6.54TB of total size.
Host B only has 1 live SQL Server VM which is not replicated but is receiving 2 VM Replicas.
SQL Server VM has a total size of 2.13TB of VHDX
Total disk cost of all VMs on HOST B leaves this host with around 1.71TB free.
Windows Server Backup runs from 6PM to 3AM and is running a full backup each time.
I believe that during this time the differencing disks are using up all the free space which is putting my running VM in to a saved state and does not recover automatically.
On top of this I am unable to have replication for the SQL VM because of the similar symptoms caused by WSB. The differencing disks werent clearing out.
Is there something I can do to get WSB to do incremental backups of these VHDXs files or is this expected to have to back up the full VHDX each time on a SQL VM?
Do you think I should replicate to Host A and back up host A instead?
Or, do I need to increase my disk capacity?
I must add that Host A running the two live VMs is having no issues with backup or replication. My issue is the SQL VM only.
thanks!
