Mirror with Excludes

This is the minimum mirroring size. Please see the mirroring tips page to find out what we recommend excluding, and why. You'll see that for the latest releases (which is what most people want) alot of space is saved.

S.L. 5.x	S.L. 5.x
50 - ?G 51 - ?G 52 - ?G 53 - ?G 54 - ?G 55 - ?G 56 - ?G 57 - ?G 5x - ?G * 5rolling - ?G **
60 - ?G 61 - ?G 62 - ?G 6x - ?G * 6rolling - ?G **

*The 'x' releases contain all the SRPMS, debuginfo, and obsoletes. Everything else in the directory is just links. This size count's ONLY the SRPMS, debuginfo, and obsoletes.
**rolling contains i386, x86_64, SRPMS, and testing. So these areas tend to be larger than most. Most places do not need to mirror this area.

Full Mirror

This is not recommended. Please see the mirroring tips page to find out what we recommend excluding, and why. But if you really do want to do a full mirror, this is how much space you will need.
