I used to know an admin that ran a CVS server for a team developers at a
microelectronics company in Colorado. Out of all of the headaches that I knew
that admin was dealing with, the CVS headaches were by far the worst and took
the longest to fix. When the CVS server was down he would quickly be
overwhelmed by requests to fix it, because during the time it was down the
developers essentially could not work. Hard disk space became an issue, and
it was very difficult to figure out which branches in CVS could ever be
deleted to make space. Occasionally hard disk corruption would be discovered
by developers (I don't know how it was detected), and when that happened it
would take about a week (or two) to get the CVS server up again due to the
lengthy tape restore/test cylcle time in trying to find a backup that was
good.
If that same admin were to have administered a server that served Git
repositories the situation would change dramatically:
- The developers could continue work because commits are done locally first
- Storage space would be much smaller [and so would be the number of public
branches]
- Repository corruption can be found by the server admin via 'git fsck'
and likewise know when a restore from backup is good
So Git (and probably other DVCSes) have server-side advantages as well.
