In order to properly backup a VMWare setup and VMs you will need to pay
money for
the relevant backup product.

Thanks for the direct Answer. Why 's that? Can you guys go ahead without*

I have used bacula before. My question is how to backup VMs running in
Ovirt?
When I can't pinpoint a VM Image? Will I have to take Whole storage such as
NSF, ISCSI or SAN (i.e - FC)

Them, How to restore?


Could you pls answer?

Not at this moment, and this is not planned for the future, afaik.

Did you play with the other SDK examples etc suggested during this thread?

May I suggest that this is best done as a plugin/contribution to a backup
solution, not standalone. I guess most sites with more than a few hosts use
some such solution - FOSS (amanda/bacula/backuppc/etc) or proprietary
(netbackup/backupexec/acronis/etc) - and backup of VMs (ovirt or other)
should be handled in this scope.

Searching the net I manage to find [1] and [2], which might be what
you want. Note that I never tried any of them myself.

Using ovirt-node EL7 we’ve been able to live merge since 3.5.3 without any

Many thanks for the above script. I ran it on Ovirt manager. It worked. It
gave me the ID of my CentOS_71 VM that I want to backup.

I rewrote the script in this way and ran it.


#!/usr/bin/python

from ovirtsdk.api import API
from ovirtsdk.xml import params

# Connect to the server:
api = API(

No error was given. I have no idea whether snapshot wad added or NOT by the
above script.

I can't display it.

*How to display it?  *

Then, *How to backup the VM with this snaphot? *

Then, finally* how to delete this snapshot? *to delete the snapshot,

I tried with below command. the did NOT worked.



*vm.snapshots.delete() *or
  *vm.snapshots.detach(*

 or
  *vm.snapshots.remove(*

I think I am have completed about 50% of this backup process. If you can
write down the  above steps, It would be very grateful.


I searched a whole lot. But , I still can't do it.

These are the links I came across.

https://github.com/laravot/backuprestoreapi/blob/master/example.py

http://www.ovirt.org/Testing/PythonApi#Create_a_Basic_Environment_using_ovirt-engine-sdk

this is your one

http://users.ovirt.narkive.com/Z29BQWAD/ovirt-users-python-sdk-attach-disk-snapshot-to-another-virtual-machine


Hmm,


*How to list the sanphot? *

*how to backup the VM with snapshot? *

*finally , how to remove this snapshot? *


Then. I think it will be OVER. Yesterday, I tried a lot.  but, NO success.

Hope to hear from you.

Not exactly "help" but AFAIK, even with 3.5, there is no live merging of 
snapshots so they can't be deleted unless the VM is down.  I know for large 
snapshots that have been around for awhile removing them can take some time too.

If you know the name of the VM then you can find it, including its id,
doing a search:

https://engine.example.com/ovirt-engine/api/vms?search=name%3Dmyvm

If you prefer to use a script, which is probably the right thing, then
you can do something like this, using the Python SDK:

---8<---
#!/usr/bin/python

from ovirtsdk.api import API
from ovirtsdk.xml import params

# Connect to the server:
api = API(
url="https://engine.example.com/ovirt-engine/api;,
username="admin@internal",
password="**",
ca_file="/etc/pki/ovirt-engine/ca.pem",
debug=False
)

# Find the VM:
vm = api.vms.get(name="myvm")

# Print the id:
print(vm.get_id())

# Disconnect:
api.disconnect()
--->8---

Once you have the VM you can create a snapshot like this:

---8<---
vm.snapshots.add(
params.Snapshot(description="My snapshot")
)
--->8---

You can also use the Java SDK, if you prefer Java.

look at:
https://engine.example.com/ovirt-engine/api/vms

it lists all the vms and shows both the VM name and it's ID

the correct address should be
https://engine.example.com/ovirt-engine/api/vms/ VM_ID /snapshots

it depends a lot on language you want to use. If you want to use for example 
python you could try this guide to python sdk

/api is deprecated [1]. Please use /ovirt-engine/api in all URLs.

IIUC it should still work, though.

The page above links also to a complete example (check "External
references" near the end). Did you check it?

You might also want to play with the examples in [2].

Not sure.

[ovirt-users] schedule a VM backup in ovirt 3.5

[Indunil Jayasooriya]

Hi list,

I want to *schedule a VM backup* in ovirt 3.5. I read below URL.


http://www.ovirt.org/Features/Backup-Restore_API_Integration#Full_VM_Backups

It gives an below example of VM backup


Example for VM Backup

   - Use existing VM Snapshot/Create a vm snapshot (example):

 URL = SERVER:PORT/api/vms/VM_ID/snapshots
 Method = POST
 (with Content-Type:application/xml header)
 Body =
 
 Virtual Machine 1 - Snapshot For Backup
 



But, How can I find the *VM_ID* of the VM that I want to backup?

How can I write this below format?

 URL = SERVER:PORT/api/vms/VM_ID/snapshots

MY Ovirt Engine manager is running on another PC. (let's say
engine.example.com ) i can access it by typing
https://engine.example.com/

is it https://engine.example.com/api/vms/*VM_ID*/snapshots ? I can't
access it in firefox browser?


Should I write a script? is there any Youtube video or doc that makes
me to understand this?

Hope to hear from you.
