until proxmox 2.2 the kvm backup file is tar.gz ou tar.lzo. Now have vma.gz ou vma.lzo.

I have a script to test backup file integrid:

for i in *.tar.lzo; do tar --lzop -xf $i -O > /dev/null 2> /dev/null;

rc=$?
if [[ $rc != 0 ]] ; then
echo Fail in $i
else
echo OK in $i
fi

With vma this not work... Any ideias ?
 
and is possible use a command to extract vma to check is ok ? or maybe checking lzo output can be enough ?
 
or maybe a qmrestore --check option ?

This file validation is very important. I see many time vzdump generate invalid files ( dont know why, but is very often)
 
Is there a page somewhere that provides more information on the vma format? I'm curious if it carries any new features or benefits.

From googling I can see there are some things on the full spec in mailing lists, but I was thinking more along the lines of a page with something like "Now with 20% more backup magic!"...or whatever points make the vma format better than just using tar.
