a Veeam novice here.. We subcontracted the Veeam Backup & Recovery portion of a project to another company.. Below are the details of the infrastructure and the current issue requiring guidance:
VMware vCenter Server v 5.5.0
Veeam Backup & Replication v 220.127.116.118
Only one host; Drive type: None-SSD; Capacity: 5.45TB; Free space: 4.81TB [already has 9 App VM replicas]
Data center site: 2 hosts; one for DB VMs, one for App VMs
For host-1, has 9 App VMs; disk backup, tape backup & replication all done... No issues there..
Physical server internal storage has eight 800GB SSD in Raid 1+0; Drive type: SSD; Capacity: 2.9TB; Free space: 1.52TB
Hosting 1 production SQL DB VM ; Provision space: 2.06TB; Used space:1.38TB
Plan: Backup & replicate the production SQL DB VM to DR
Issue reported by subcontractor: Free space available in repository of the host of the production SQL DB VM is not enough for the VM snapshot to be taken during the snapshot process including the space required for corresponding tasks for the replication process. He says if the replication job is started and if there is issue on the job process completion [i.e. during taking snapshot, creating backup, delta files, compression, data moving, decompress, write, commit vm snapshot, consolidation..], there is a chance that the source production SQl DB VM might fail...
He suggests that the DB size be optimized/reduced [as the actual DB size is much smaller... which requires support with another vendor supporting the DB]
OR he asks that source host datastore be increased by adding two 800GB SSDs.
Kindly help to understand if this is a correct assessment by the subcontractor.
