Snapshot 101: Copy-on-write vs Redirect-on-write

Good post by W. Curtis Preston (thank you)

There are two very different ways to create snapshots: copy-on-write and redirect-on-write. If IT is considering using the snapshot functionality of their storage system, it is essential to understand which type of snapshot it creates and the pros and cons of using either method.

Rather than the more common term volume, this column will use the term protected entity to refer to the entity being protected by a given snapshot. While it is true that the protected entity is typically a RAID volume, it is also true that some object storage systems do not use RAID. Their snapshots may be designed to protect other entities, including containers, a NAS share, etc. In this case, the protected entity may reside on a number of disk drives, but it does not reside on a volume in the RAID or LUN sense.

Protecting NFS storage on vSphere using Veeam virtual proxies

Good post by Luca Dell’Oca (thank you)

Since Patch 3 of Veeam Backup & Replication v7 (build 7.0.0.839) there has been a new mode to manage hotadd backups over NFS, available via a registry key. Per the original release notes:

“Intelligent load balancing can now be configured to give preference to backup proxy located on the same host using the EnableSameHostHotaddMode (DWORD) registry value.”

I’ve kept this post on hold for a while, since with the upcoming v9, DirectNFS will be a much better option than virtual proxies to backup virtual machines running on NFS shares. But there are situations where this key may be still needed, like people still wanting to use virtual proxies against NFS. So, what is this key, and what you can do with it?

Modernizing Your Infrastructure with Hybrid Cloud – Hyper-V over SMB

 

Good post by Matt Hester (thank you)

In today’s post in the modernizing your infrastructure with Hybrid Cloud series, I am going to talk about Hyper-V over SMB, which we introduced in Windows Server 2012.  It is also important to note that you can use storage spaces to house your SMB share that Hyper-V will leveraged.  In Part 7 I talked about storage spaces:  Modernizing Your Infrastructure with Hybrid Cloud – Storage Spaces in Windows Server 2012 R2 (Part7)
