blockchain backup with git: revert not working

[curiosity81]

Hi,

currently I am testing git for backuping blockchains in the corresponding chain directory:

Code:

git add *
git commit -m "<some text>"

However, if I try to revert a commit using

Code:

git revert HEAD

the resulting chain directory is messed up, i.e., starting *coin-qt reports a broken blockchain and wants to start downloading the whole db again.

Actually I though that a revert would restore a former state of the blockchain. But this assumptions seems to be wrong. Anyone an idea what is going wrong?

For test purposes, I use the feathercoin blockchain and feathercoin-qt since the corresponding db can be copied relatively quickly.

Thanks in advance for your help.
