Exchange 2010 VM
Windows 2008 R2
Esxi 5.0 with 6TB of free space on an SSD Datastore (DAS)
VM had two Hard Disks (C: System - 200GB) & (D: Exchange databases - 1.7TB) . Both Thin Provisioned.
Veeam 18.104.22.1683 : This VM is backed up (forward Incremental) & replicated daily.
The VM was close to running out of space on the D: drive & we shutdown the VM & increased the Provisioned size to 2TB, then extended the D: partition in Windows. Obviously, if we had done more research, we would have known that this will be a significant issue with snapshots & that VMware are a bunch of idiots for allowing the option to 2TB's.
The Hard Disk 2 (D:) VMDK provisioned size is now 2,147,484,000 KB which is over the snapshot limit & we can no longer create a snapshot of the VM - causing our Veeam backups & replication jobs to fail on this VM. (actual used space of the vmdk is 1,849,798,000 KB).
The only solution is for us to add another Hard Disk 3 (1.9TB) to this VM, copy the data from Disk 2 (D:); then delete Disk 2, & make Disk 3 the D: drive in Windows.
Before I do that, I need to know what type of issues I will run into during Veeam Backup & Replication.
-Will the backup job assume the data on Disk 3 on this VM is brand new & create a large 1.7TB+ forward incremental .Vib? Or is it smart enough to know this is the same data that has already been backed up?
-Will the replication job assume the data on Disk 3 on this VM is brand new & create a large 1.7TB+ VMDK snapshot on the destination datastore? If yes, can I use the "Low connection bandwidth" replica seeding option to alleviate this issue (because the replica's are at our DR site with only a 150/150Mb fiber connection. It will take 18+ hours to replicate 1.7TB).
Thank you in advance.
