Instant VM Recovery

Post by ChrisJ83Knights » Oct 30, 2017 10:26 am

Hi

We are currently in the process of doing a spec for our backup server and wanted to ask a question in relation to backup file location.

One of the VMs we backup has high IOPs requirements and needs to be on SSDs in the production environment, with this in mind the spec at the moment is LFF disks with SSD for cache for all backups apart from the VM in question. We would then have another array of SSDs in a RAID 5 configuration where the VMs backup files would sit.

Would this then mean when doing an instant VM recovery on the VM it would utilise the SSDs as the backup files sit on them? Giving us the IOPs required?

Is there any other folders through Veeam which hold the temp/changed files of Instant VM Recovery that would benefit from being on the SSD array as well?

Any help/advice appreciated.

That's correct, the more IOPs you have on the repository storage the better performance you'll get.

Nope, the changes during instant recovery process will be written to the production storage. Thanks!

Is it possible to change VM parameters for instant vm recovery of agent backups? At least to recover disks as thin provisioned (not to get space on storage up to maximum size of a physical devices), memory size and cpu count?
Suddenly disaster-recovered VM made from physical servers can me a large smaller than original hardware, but now ther need to have a 16 cpu and 256 GB ram vm to make instant restore from 16 cpu and 256 gb server.

No, these parameters cannot be changed upon Instant Recovery.

Does Instant VM Recovery just utilize the latest incremental backup or does it use the latest full and incremental?

Chris,

If you select the latest restore point (and it is an incremental) it will start the VM based on the needed data in the chain. That means it needs a full and 1 or more incrementals to become the VM again. With the incremental alone it won't have all the data needed to start the VM.
