need FLR restore from GPT disk

Post by pnikies » Mar 18, 2011 1:43 pm

hello, this a request for new feature
our customers need to file level restore GPT disk and it's not supported with veeam backup
it's more and more critical. Will this feature happen in near future ?

thank you

Hi Roman, no this feature is not planned for near future. We are monitoring the need, but demand has been pretty much non-existent (very occasional requests). There is simply no sense to deploy VM with GPT disks today. The only benefit of GPT is support for >2TB disks, but VMware has 2TB VMDK size limit today anyway. Thanks.

You can perform a file level restore by leveraging the SureBackup or Instant Recovery feature, but I will that not having this feature seems strange. Yes there are only limited advantages to GPT for filesystems less than 2TB, but some advantages do exist (redundant copies of the partition table and CRC32 to detect problems with the table, improved alignment capabilities), and some VM's were created with GPT as physical machines and came over with P2V. Some companies also standardize on GPT for 64bit servers since this appears to be the future.

Please put GPT support on the roadmap!
We made at some I/O intensive VM's the data disk to GPT to get rid of the performance degration what you have with a non-aligned MBR disk.
Sure you could go through this hassle.... http://support.microsoft.com/kb/929491

Oh, it is on the roadmap... there are just way too many other pending features too ;)

Agreed, I'd love to see this.

In my situation I actually had to go out and buy Acronis Disk Director to convert GPT to MBR (There's a free tool that'll do it as well, but you know how it is!).

Thanks Alex, for the tip with Acronis. I'll try that. I saw the free tool from Paragon, didn't look very promising (were some comment of problems and haven't releases any updates for a year).

No problem. If you want to check out the free tool (which actually worked in testing), it's called gdisk.

Thanks. I converted the GPT disks to MBR with Acronis last weekend. I had to install the software on the server because the Linux boot media does not work (Stuck at booting with Starting Acronis Loader). I haven't had time yet to try a WINPE Acronis boot media.
Now of course the partitions are no longer aligned right. I found here an article to align paritions without removing everything from the disk: http://www.tuxyturvy.com/blog/index.php ... -Data.html but I haven't tried it yet.

That's my article. It works, but is tedious. It's one of the most hit articles on my site.

I'm curious, why does converting from GPT to MBR cause the alignment to change? Does the Acronis tool actually move the partition? I would have thought it would have simply left the partition in place and wrote a new MBR which wouldn't actually change the alignment if the partition was previously aligned.

Small world :) Great article. It is probably less time consuming than to move terrabytes of data around.
I checked after converting and it was not properly aligned. It does not matter that much in my case because we'll install a new Exchange and file server in a few months anyway.

Veeam.... please try to prioritize GPT FLR support on the roadmap... Our infra guys are deploying lots of GPT servers and a simple file restore requres me to boot the server in Virtual Lab...

File Level Restore GPT Partition

Post by kurt » Apr 11, 2011 3:10 pm

[Merged into existing discussion]

I found out the hard way that FLR does not work on GPT partitions. This is a huge disappointment.

I have a 1.25 TB drive with about 900GB in use. I need to restore one tiny file. What is the quickest way for me to restore that file?

Our solution to this is typically to perform an Instant Recovery to an isolated network. We have Windows host which has a secondary NIC connected to an isolated vSwitch. We perform an Instant Recovery and connect this host to this same isolated vSwitch. That way these two systems can see each other and you can copy the file off, but the Instant Recovery doesn't interfere with the running system.

There are other similar way to accomplish this with virtual lab functionality.
