Re: Async backup

[Granwille Strauss]

Correct me if I am wrong, all snapshots make a local copy to the management server disk before sending it to the secondary storage locations, yes. Async or not. But yes, I believe that is the case. However, when async is enabled you get to use and work on other tasks with the management server, while it does the snapshot process in the background. Whereas having async disabled, you are restricted from doing other task on the management server until the snapshot process completes, that's how I understand it.

Thank you, Granwille for your prompt answer.

Can you elaborate on the "locally"  and "storage location" terms?
On a host that has multiple primary storages (e.g. NFS and some other storage 
over iSCSI)  but no local disks are used, what is considered as 'locally'?
Also, by "storage location"  do you mean the secondary storage?

In short and in layman's terms, it makes the volume snapshot, stores it locally 
and then in the background transfers it to the storage location. This helps 
with server resource usage. But see attached screenshot for a detailed answer.

Hi All,

Can somebody explain what the "Async backup" option does while taking volume 
snapshot?
