Can I use LVM Snapshot backup for KVM in 3.1?

[dietmar]

The VM disk is 354334MB

For testing, please can you also post the backup log for:

# vzdump 156 --compress 1 --stdout>/dev/null

 

[e100]

Please can you post the full backup log (so that I can see read/write speeds)?

June 30th:

I am confused now - both logs are from the new backup method!

 

[e100]

For testing, please can you also post the backup log for:

# vzdump 156 --compress 1 --stdout>/dev/null

#vzdump 156 --compress 1 --stdout>/dev/null
can't use storage for backups - wrong content type

So I did this instead:

# vzdump 156 --mode snapshot --compress 1 --dumpdir /backup --stdout > /dev/null

I am confused now - both logs are from the new backup method!

Seems like you are right and I am mistaken. I thought that the new backup method was in 3.0, but it was in 2.3.

Lets start over, maybe I am overlooking something due to my erronious thought.

So my problem is that load average during backups has increased substantially with recent Proxmox changes.
I have provided the ls -l of /boot so we can view timestamps of kernel updates (which would coencide with Proxmox upgrades) along with graphs of load averages.
There seens to be a rather consistent pattern.

INFO: transferred 354334 MB in 880 seconds (402 MB/s)

That shows that speed on the DRBD side is OK.

 

[dietmar]

So my problem is that load average during backups has increased substantially with recent Proxmox changes.

Please can you test the write speed on the backup target.

a.) create a backup to local storage ==> test-backup-data.vma.lzo
b.) copy that to the backup target storage and observe load/speed: cp test-backup-data.vma.lzo /backup/dump/testfile

Note: The logs you posted clearly show a drop in target write speed (from 100MB/s to 30MB/s)

The new KVM LiveBackup feature is great, but I believe it is causing issues for some windows VMs.

..

How can I install the older version of vzdump that used LVM snapshots when backing up KVM?

Hello e100,

if you consider using LVM snapshots again, we have very good experience with storebackup since two years.

Started here:
http://forum.proxmox.com/threads/44...ession-binaries-and-configuration-for-backups

Especially because it don't need much space for incremental backups (compressed and deduplicated blocks) and we can run consistency checks (based on md5) on the fileserver. So it is a bit more CPU intensive. But for us double checked backups are more important..

This is off topic, and does not help. But your images caught my eye, and I have no way to PM you.
What are you using for network monitoring?
I have tried Pandora FMS and nagios, but neither use SSH regularly, and they require heavy SNMP implementation. I am looking for something similar to PRTG without the Paessler price.
Thanks!

e100, I'd like to have LVM snapshots back in proxmox too. I don't think there's any reason you can't just script the snapshots to run and do it yourself. I'm heading down this route as they are doing something new and undocumented with these backups - so it is proprietary. Long term outlook of these backups is grim, so for archival purposes you'd never use them.

Unfortunately, though we're told it's 'not possible' to have LVM backups as an option it certainly is as it was working great, then removed from the code. This is just not an option the project managers want available.

My testing has shown that performance restoring backups on this new platform with vmdk containers can be horrible. This may be the case for qcow also but I've not tested it.

Did anything ever come of this? Did you figure out the cause?

 

[e100]

Did anything ever come of this? Did you figure out the cause?

I've not found the solution of why backups are slower in 3.x vs 2.x
If I ever figure it out I will post the info here in the forum.
