I have a 3tb D: drive (SAS RAID array) storing a 2tb vhd of a VM.<br />
<br />
I have a 3tb SATA drive (E:), which holds a ~600gb .avhd snapshot<br />
<br />
I also have the most recent child .avhd snapshot fragment which is ~350gb running on the D drive.<br />
<br />
I plan to manually merge the 350gb and 600gb fragments using this guide: <br />
<a href="http://itproctology.blogspot.com.au/2008/06/how-to-manually-merge-hyper-v-snapshots.html" rel="ugc">http://itproctology.blogspot.com.au/2008/06/how-to-manually-merge-hyper-v-snapshots.html</a><br />
<br />
The problem is, my copy speed from the SATA drive is only 30MB/s. That means it'll take nearly all day to do the merge - and I only have a maintanance window of 10hrs to get this done - and I'll be left with no space on the D drive for additional growth of the fragments.<br />
<br />
Array is full so can't add more disks.<br />
<br />
Is it safe at all to run a compression on the base .vhd or any of the .avhd's?<br />
<br />
Is there any other way I can compress them or reduce their footprint?

Can I compress a hyper v snapshot .avhd

The Microsoft Server topic includes all of the legacy versions of the operating system, including the Windows NT 3.1, NT 3.5, NT 4.0 and Windows 2000 and Windows Home Server versions.

Microsoft server applications are those applications developed specifically, but not necessarily exclusively, on the Windows Server platform. In addition to well-known products like SQL Server, Exchange, Internet Information Services (IIS), Microsoft Dynamics, Forefront, Lync and Sharepoint, they include applications like Skype, BizTalk, Hyper-V, Groove and Commerce Server. Server applications are managed with the Microsoft System Center.

Microsoft Virtual Server was a virtualization solution that facilitated the creation of virtual machines on the Windows XP, Windows Vista and Windows Server 2003 operating systems. Virtual machines are created and managed through a web-based interface that relies on Internet Information Services (IIS) or through a Windows client application tool called VMRCplus. Features included Linux guest operating system support, Virtual Disk Precompactor, symmetric multiprocessing (SMP), x64 host operating system support, the ability to mount virtual hard drives on the host machine and additional operating systems support, including Windows Vista, and a volume shadow copy writer.
