Hi Guys

There is a really good explanation of VMCTLMC Sizing for incremental VM backups 
at  http://adsm.se/?p=546
I run a monthly full for compliance reasons on all the Prod Vms, and am trying 
to understand the implications for   VMCTLMC Sizing.  So far I suppose its 8000 
megablocks  as well as 8000 control files per TB so  8000*(128+73) KB ~= 1.5 
MB/TB.

As there is a 7 year retention for these I see why I'm running out of space.

The only option I can see would be a 1 year retention and a monthly export to 
tape for this data.  What do others do?

Cheers
