vPower questions

Hi

Done a search but couldn't find anything.

As I understand it, vPower allows you to boot up a VM directly from a backup file, which is great.

However, what happens with changes?

I.E Exchange Server crashes for whatever reason, and you use vPower to bring up the Exchange backup from the previous night.

What happens next?

Do you move the vPower VM into production, but lose everything between the previous backup and then the production VM went down?
Or do you shutdown the vPower VM, and try to fix production? What happens to the changes made when the vPower VM was serving?

If you are talking about Instant Recovery, then you need to finalize it by migrating the recovered VM into production (either using sVmotion or Veeam B&R Quick Migration feature). This will migrate the instantly recovered VM in its entirety from vPower NFS datastore to your production datastore. If you are running version 6.1, you can just right-click the published VM and select Migrate to production. This option will work whether or not you have Storage VMotion licensed.

Thanks.

So if say the Exchange server went down in the afternoon and I used the Instant Recovery to get users back on via the previous night's backup. In the evening I would migrate it back into Production.

However this method still means we could lose a morning's worth of data.

Are there any other technologies which could help in this situation? Something like CDP?

Veeam supports "near-CDP", it's not exactly CDP but it allows for really frequent backups, basically as soon as the previous backup finishes, a new one is started, without any pause. On an exchange server with high IO though snapshot commit can take some time, so a single cycle can last several minutes.
