I did started to contact some people to find Tier1 mirrors. One question
come immediatelly: what will be the size of our mirror tree ?

To have an idea I checked the mirror of the current Mandriva cooker and
the result make me afraid.

The current cooker tree (RPMS + installer only) is 88GB (SRPMS + i586 +
x86_64). If I add 3 DVD iso (4GB each) I get around 100GB.

This mean at the begining our mirror will be ~80 GB and in 3 years (1
release every 6 months) our tree size will be around 700GB !

700GB is an huge size. I know anyone can buy a 1 TB hard drive for a
small price, however this is not the way it works in real datacenter
where people take care to the safety of data (RAID1 is two disk). And
we have to think to future: what will be the size in 6 years ?

The current full Mandriva mirror is more than 1,2 TB.

So an immediate question come: should we try to reduce the size ?

There are solutions, but they implies changes in our development
process and have counter parts:
- using hardlink between RPM:
  - can be done for noarch inside a release
  - no resiging packages from cooker to stable at release (rpm changes,
    any possible hardlink get broken)
- do not push -debug: will bother others developers
- removing old distro (having another tree for old): this usualy
  bother people having old distribution still working on some
  computers, 3 years is not a so long timelife

- is this kind of size an issue ?
- do we have to reduce it ?
- do you have comments/idea about this state ?
