Feature: Configuring a storage domain as backup storage domain, so user can backup VMs and Templates while the storage domain is attached to oVirt Reason: Export storage domain is a dedicated storage domain which is used to store and restore VMs and Templates. The drawback of Export storage domain is its two stage process. Transferring a VM required first copying it into the export storage domain and then into other storage domain to start using them. Since in background transfer from one domain to other take place using normal copy or dd utility (in case of disks) this process take a large time for a complete transfer. Result: For a better backup experience we decided to create a whole dedicated storage domain to be used only for backup which obviously will call as backup storage domain.

Description Allon Mureinik 2015-12-14 08:22:15 UTC 
Description of problem:
With the ability to attach/detach a data domain, it can virtually replace an export domain.

The missing piece is a "backup-mode" flag to allow the user to prevent running VMs on the copies he intends for a backup.
Comment 1 Allon Mureinik 2017-06-12 07:47:31 UTC 
Actually, this is being worked on as part of oVirt's participation in GSOC.
Comment 2 Yaniv Lavi 2017-08-13 11:04:21 UTC 
A nice follow up would be to allow to attach this domain a number of DCs and RHV managers to enable easier template sharing with OVA/templates. Should we open an RFE for this?

I'd like to point out that this isn't *that* easy.
Nothing in this feature changes the locking implementation, so there's quite a bit of extra work to add the improvement you're requesting. Let's have a separate RFE for it so we can design/scope/prioritize there.

Shubham,

Can you please open a separate bug for the fix in https://gerrit.ovirt.org/#/c/81290/
and block this bug on the new opened bug.
I think that once that will be done we can move this bug to ON_QA
Comment 8 Raz Tamir 2017-10-15 08:46:22 UTC 
Maor,

Can you please provide more information about this RFE?
Is there any feature page for it?
Comment 9 Maor 2017-10-15 09:17:50 UTC 
You can take a look at the feature page here:
https://github.com/oVirt/ovirt-site/pull/1003
Comment 10 Elad 2018-02-19 12:33:04 UTC 
Feature functionality works properly, the following operations are blocked:
- VM start, with an attached disk on a backup domain 
- Setting a domain to backup while it has disks attached to running VMs
- Live storage migration to a backup domain (as bug #1541769 is now fixed and verified)
