So my web server is an IaaS VM in Azure, but, you know, apparently "things happen."

I'm used to hooking up an extra USB drive and doing image backups there.  I can then get different hardware and do a restore and I'm up in a couple hours.

What is the Azure/cloud version of that?  Thanks.

You can do snapshots of your machines in azure. I know a snapshot is not a backup but at least it's something. Terrible slow in restoring though.

Two main backups available within Azure.

File and Folder
VM

I'd run a File a folder daily for 2 to how ever long you wish the files recovered.
Then run a VM backup weekly.

The File and Folder backup and restore isn't too bad.
The VM backup - somewhere between 10 to 20 hours!

Restore of a VM isn't too bad - maybe 1 hour for a 50GB VM, as long as the VM backup process has finished!

I've played a lot with Azure VM backup lately. Some things that I've learned:

> The VM backup - somewhere between 10 to 20 hours!

The first backup is always longer, the next ones are incremental. For a small machine (DC) I'm seeing 2h initial backup 20m for the next ones. Once in a while you will get a much longer running backup.

The restore is reliable, I have not seen it fail yet. A full DC restore (20 GB) takes about 20m.

The powershell commandlets are only available in Service Manager mode. The ARM version is underway.

And finally: the VM backup requires internet connectivity from within the VM. That is going to be an issue for highly secure  machines. However, MSFT publishes the Azure VM endpoint subnets so you could conceivably limit outgoing traffic to those subnets only.

Willem,

We have a lot of mixed loads, different sizes and shapes.

These backyp times are not uncommon., 4 machines, 2 X 25GB, 1 X 40 GB 1 X 250GB
Servers have been in place for 4 months.

Joe, that's just very slow. I'm trying to understand what might be happening. Assuming that the disks are almost full and the daily change rate is as high as 10%, the IO throughput is only 1 MB/s which is ridiculous.

How much data do you actually have on these servers, and how much of that is changed on a daily basis? Is it possible that your data is highly fragmented (which would make delta processing inefficient)?

  • with this long backup times their backup periods must overlap which could be a problem. Do they perhaps also share the same cloud service?
  • VSS taking a long time, perhaps? Could have multiple causes.

Willem, overall trying to find an answer or information was damn tough and then I heard about an Azure Backup AMA.
So I joined in.
The time on backups was explained to me as such on the AMA
https://www.reddit.com/r/AZURE/comments/3w81k5/ama_azure_backup_team_1210/

About 2/3 way down.

f2003629 Azure 1 point 1 month ago 
  • Azure IAAS VM backup is split into 2 phases. The snapshot is taken first, say within 15 minutess of the backup schedule time. The state which is backed up is corresponding to this time, within 15 minutess. Then the snapshot is transferred to the backup vault, in the second phase of backup, this time is considerably longer and depends on the changes between the consecutive backups, or whether it is the first backup.The recoverability of the backup is possible only after the second phase of backup is complete

These are full guest backups - yes we are looking to change.
The rate of change is small on these and on others.

File and folder backups are a lot quicker.
Full VM backups are as yo can see somewhat ridiculous, but thats life in the cloud.
Some sites are LRS, some are GRS, no difference in the consistency of backups.
Some are (more occasional than common) 20 min backups
Common is 6 to 8 hours.

Could be dues to mix of backup policies, non standard policy as defined by customers RPO/ RTO and time to keep.

I have not looked at DPM since 2012, replaced DPM with Veeam where we can for all sorts  of reasons.
So not sure how they are getting/ giving me the backup policy options of daily, weekly, monthly and yearly as we don't see that option in our current DPM deployments.

Joe called it all out on the "MARS" offering (Microsoft Azure Site Recovery) and there is;
Microsoft Azure Backup, this may be more appealing.
https://www.microsoft.com/en-us/download/details.aspx?id=49170

"Microsoft Azure Backup provides backup for rich application workloads like Microsoft SQL Server, Hyper-V VMs, SharePoint Server, Microsoft Exchange and Windows clients with support for both Disk to Disk backup for local copies and Disk to Disk to Cloud backup for long term retention."
