Instant recoery VS restore full VM

Veeam Logoby hasayeretFMG » Fri Jun 30, 2017 1:33 pm

Good morning,

Is there any documentation which compares pros and cons of instant recovery and full VM restore?
It almost feels to me that 99.9% of the cases instant recovery will be the way to go since the machine is always accessible to the users and you can still perform a migration.
In fact, I almost do not understand why the restore full VM option is still available and the only reason I can think about is that it might be a faster way to restore since the machine is down and no changes are being made on it (like in an IR scenario)

Thoughts?

Instant VM recovery's performance is dependent on a large number of factors. The primary one that can have a major impact on running production vms this way is the type and speed of your backup storage.

Instant VM recovery is great as an option for some scenarios, but in others it can be almost useless. A common example would be for enterprises that use FiberChannel for their production SAN and do not have adequate Ethernet infrastructure to run storage traffic for production VMs as well as normal networking.

A full restore will always "work" to restore your data to some kind of production storage, instant VM recovery is situational.

Thank you so much for your answer!
In our case, we are running our Veeam on the same server where the Veeam data is stored: A windows server with just tons of disks while our production environment is really a SAN-based environment. Sounds like in our environment Instant Recovery would be the way to go? Or did I miss something

Again, it is situational and will vary between every instance you need to recover your data.

If you have one VM that crashes and want to get it back up? Instant VM recovery is probably fine.

Every VM you have gets whacked with a crypto-locker and you need to restore them all? Doing a series of Full restores to your SAN would likely be a better option for most VMs.

Instant recovered VMs are added to your VM environment as new VMs with new UIDs so you need to take that into account when you use Instant Recovery+storage migration to get them back on your production SAN.

Thank you!
We have a 1.1TB Exchange server which needs to be moved from 1 host to another and we realized that do that through Veeam would be the fastest way.
I assume that in a situation like this when we have our emails available all the time, instant recovery would be the best way since the machine is online all the time. Correct?
