I still think that storing an amount of data inside a smaller file is ‘compression’, regardless of how much is actually used inside the RAW file (is RLE compression still a thing?), but that does answer my question. It’s a shame, because I’ll now have to extract backups as they’re created somehow in order to get them into a state where they can be de-duplicated again. I think many people would appreciate a file format inside which the data is aligned, even if it is out-of-order to a degree. I won’t be the first person who has virtual machines which don’t change much.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>[1] http://forum.proxmox.com/threads/13475-Proxmox-2-3-new-backup-methode-vma-not-rdiff-friendly<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0cm 0cm 0cm'><p class=MsoNormal><b><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> Yannis Milios [mailto:yannis.milios@gmail.com] <br><b>Sent:</b> 13 November 2014 16:32<br><b>To:</b> Chris Murray<br><b>Cc:</b> pve-user@pve.proxmox.com<br><b>Subject:</b> Re: [PVE-User] Uncompressed backups are compressed?<o:p></o:p></span></p></div><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal>VMA is the new backup format since PVE <a href="http://2.3.It">2.3.It</a> is uncompressed and it should reflect the actual data occupied inside your vm (not raw file size).
