[ovirt-users] Backup bug in latest version

2024-06-13 Thread Giulio Casella


Hi,
yesterday we upgraded engine:

ovirt-engine-4.5.7-0.master.20240506114300.git0a1ba8203f.el8.noarch -> 
ovirt-engine-4.5.7-0.master.20240527152413.gited023e5e0a.el8.noarch


Since then our backups (made by Storware backup and recovery, vprotect) 
are failing.
It seems that engine tries to add backup twice, and db primary key 
constraint obviously fails. Find below a snippet from engine.log.


The snapshot part of backup process is executed correctly (but snapshot 
named "Auto-generated for Backup VM" remains after failure).


Also script 
/usr/share/doc/python3-ovirt-engine-sdk4/examples/backup_vm.py fails to 
finalize/terminate backup.


Has anyone seen this and filed a bug on github?

[ovirt-users] Backup/restore of Hosted Engine VM

2022-09-26 Thread Volenbovskyi, Konstantin

Hi,

I am aware that there is a procedure of backup/restore documented in 
https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.2/html/self-hosted_engine_guide/backing_up_and_restoring_a_self-hosted_engine
 , but I would like to have also else as well when it comes to backup (and 
restore) of hosted engine VM and avoid using hosted-engine --deploy / 
engine-backup

Is anyone doing Libvirt snapshot or any other similar thing to back up ovengine 
VM?
Part of that is the XML of the HE VM should be intact, so currently I am 
considering 
https://libvirt.org/kbase/live_full_disk_backup.html#full-backup-with-older-libvirt-versions
and https://gist.github.com/cabal95/e36c06e716d3328b512

BR,
Konstantin

[ovirt-users] Backup prozess

2022-02-14 Thread marcel d'heureuse

Moin,

We have in our Environment 12 servers managed by one self hosted engine. It is 
ovirt 4.3.9. We are Freizeit on that Version.

How did you make Backups? We use a github Script which generate via api a 
snapshot and Mount this disk into the vm where the backup Script is running. 
The backup Script Export this additional Hard disk to a storage and disconnect 
the disk and remove the snapshot.

This works on Linux vm fine if they have Medium load. If we try this with a 
Windows 10 vm or Windows Server vm or a Linux vm with high load or with a very 
big Hard drive this will not work. Disk can't Export and snapshot will not 
delete. 

I have found winchin and bareos but I have not start to check this first I want 
to have some more possible options. 

Thanks

Marcel

[ovirt-users] Backup to tape

2021-08-24 Thread duparchy

Hi, 

Part of our Disaster Recovery Plan we do tape backup.

Our previous infrastructure was Oracle VM and VMs fisk were files (.img) we 
could apply filters to our tar and backup to tape only required files.

Now preparing the migration to Oracle flavor of oVirt (OLVM).  
VMs disks are LVM partitions, within  an iSCSI LUNs.

I've tested "dd" to backup  the entire iSCSI LUN to the tape. Seems OK 
,providing the right block size we achieve reasonable performances.
Though I don't quite see how to have that granular backup we had, in a simple 
manner, which a goal too.

Although there is compression at the LTO level, the dd conv=sparse parameter 
may speed-up things. To be tested.
I'm just wondering if conv=sparse may breaks things at the LVM / qcow2 
containers ?

[ovirt-users] Backup software recommendations

2020-04-30 Thread Colin Coe

Hi all

I'm looking for recommendations for backup software.  It needs to handle
physical and virtual Linux and Windows, RHV and Hyper-V.

It doesn't have to be open source and it doesn't have to be free.

The main features we need are:
- disk to disk backups
- inter-site replication with rate limiting
- be able to handle Linux thin volumes (think RHGS)
- support BMR ans granular file / directory restore
- correctly handle Windows VSS
- support RHEL point releases as soon as they are released

I'm as much after "stay away from" as recommendations.

We currently use Arcserve UDP and it is ... well ... sub optimal

Thanks in advance

[ovirt-users] Backup Solution

2020-02-06 Thread Christian Reiss

Hey folks,

Running a 3-way HCI (again (sigh)) on gluster. Now the _inside_ of the
vms is backup'ed seperatly using bareos on an hourly basis, so files are
present with worst case 59 minutes data loss.

Now, on the outside I thought of doing gluster snapshots and then
syncing those .snap dirs away to a remote 10gig connected machine on a
weekly-or-so basis. As those contents of the snaps are the oVirt images
(entire DC) I could re-setup gluster and copy those files back into
gluster and be done with it.

Now some questions, if I may:

- If the hosts remain intact but gluster dies, I simply setup Gluster,
stop the ovirt engine (seperate standalone hardware) copy everything
back and start ovirt engine again. All disks are accessible again
(tested). The bricks are marked as down (new bricks, same name). There
is a "reset brick" button that made the bricks come back online again.
What _exactly_ does it do? Does it reset the brick info in oVirt or copy
all the data over from another node and really, really reset the brick?

- If the hosts remain intact, but the engine dies: Can I re-attach the
engine the the running cluster?

- If hosts and engine dies and everything needs to be re-setup would it
be possible to do the setup wizard(s) again up to a running point then
copy the disk images to the new gluster-dc-data-dir? Would oVirt rescan
the dir for newly found vms?

- If _one_ host dies, but 2 and the engine remain online: Whats the
oVirt way of resetting up the failed one? Reinstalling the node and then
what? From all the cases above this is the most likely one.

Having had to reinstall the entire Cluster three times already scares
me. Always gluster related.

Again thank you community for your great efforts!
