difference between VR and Veeam

[baber]

dear all

hi

what is difference between vr and veeam for synchronization ? Just for replica and sync machine?

i have read that but some parts of that could not understand correctly:

1- Do we have any restore point in vsphere replication ? (for example if i config that do synchronization every 10 min can i restore to previous 20min?

2 - in the document say VR no failbak is that mean if we do failover for failback we have to do recovery machine as a protected machine ?

Best regards

VR supports MPIT (Multiple Point in Time) snapshots. It is able to take/retain up to 24 on a flexible schedule. They are maintained as snapshots on the target site. After the VM is recovered they appear as a snapshot tree and the VM can be rolled back to one or the snapshots can be consolidated.

With VR only (when not using SRM) after you failover there is no automated failback (or failback button, as there is with SRM). Failback requires configuring VR in the opposite direction and then recovering the VM at the original site.

‌is your means that for example if we config VR do sync every 20 min via VR we can not back to 40 min ago ? we have to back 20 min ago and after my vm run on recovery host from snapshot i have to select 40 min ago ?

[vbrowncoat]

You are correct. You would recover the VM (it doesn't need to be powered on), then select a snapshot (how PIT appear after recovery) to revert a VM to, then power it on.

Keep in mind that VR supports a maximum of 24 points in time maximum. These are configured by selecting "points per day" & "days to retain". These 2 numbers multiplied together have to be less than or equal to 24 (eg 24 points per day x 1 day, 4 points per day x 6 days, etc)

excuseme

so thanks from your answer but in some parts confused :

1 - is that correct if i sync my vm every 30min when protected vm fail and i start second vm on recovery site it will automatically back to last 30min ?

2 - we can just keep 24 points per day ?

3 - is that means for get Twenty-fifth of snapshot the first snapshot will be remove and Twenty-fifth of snapshot will be replaced with first snapshot ?

Best regards

- VR supports setting an RPO (recovery point objective) for a VM. The lowest it can be set is 15 mins. I'm not exactly sure what you are asking here. If you have the RPO set to 30 mins, when you recover that VM the oldest it would be (assuming no RPO violations) is 30 mins.

2 - we can just keep 24 points per day ?

VR supports keeping a maximum of 24 points in time, so you could keep 24 for 1 day, 12 each for 2 days, 6 each for 4 days, etc.

3 - is that means for get Twenty-fifth of snapshot the first snapshot will be remove and Twenty-fifth of snapshot will be replaced with first snapshot ?

Yes

thanks

now if i get 24 points when i run recovery machine will it to lasr recovery point time?

i have got 24 restore point now if i want back to twentieth have to first restore to twenty fourth of point and turn on machine then restore twntieth snapshot?

best regards

[vbrowncoat · Accepted solution]

When you recover the VM it will recover to the most recent replica (not PIT) and the 24 PITs will show up as snapshots in the snapshot manager.

Then you would choose the snapshot you wanted to go back to, select it and "revert to", and delete any remaining snapshots.

thanks

for create replication on vm there is an option with name Point in time instance i have attached a pic

can you say me what feature it will give me if enable or disable that

Warm regards

We were running the original VR 1.0 with SRM 5.  Since upgraidng all components to vSphere 6, SRM 6.1 vR 6.1 I see the multiple point in time option but have not turned that feature on at this point because we never had it before.

If I turn it on, what kind of additional overhead does this create on our I/O?  How about on our network?  I have the VR ports throttled about 80mbps on a 100mbps WAN link to our DR site, so I just want to know if its going to impact the amount of data required.

What I could see doing is perhaps adding more point in time recovery points for file servers.  Perhaps if a file server is copied every hour and lets say we are struken with Ransomware.. .perhaps we could go "back" an hour and copy those files back from the DR site to the Production site VM, assuming we could get both VM's to co-exist (duplicate name on the network, etc...).

We do have Veeam but its not licenced for Replicating over the WAN like that.  We run Veeam backups nightly, and those backups on an Exagrid dedupe appliance is also copied over the WAN to the DR site appliance.  A Veeam VM at the DR site can restore any backup at that side from the previous nights backup... but we are looking for a more recent option in case of ransom, virus, corruption, etc...

Just curious if this product and feature could fill that gap and what kind of procedures should we take should ransomware make it through our many other lines of defenses.

Can you please ask this as a new question?
