Those are very bandwidth intensive services, BK uses a tiny fraction of what they use, and you can accomplish the same thing with a rm -rf /tmp/exported_tree bk pull bk export -tplain /tmp/exported_tree That's way, way, way less bytes moved to get you a perfect mirror. I really don't care if you use BK or not to do development, that is up to you. But you should use it to conserve bandwidth and you must use it if you want the data from us. I can easily understand you not wanting to learn a new tool, or having some other reason, valid or otherwise, not to use BK. That's fine. But you need to understand that anyone providing a hosting service is spending money to do so. We've spent about $25K to date. Right now, we're behind a pair of T1 speed DSL lines that cost us about $800/month. If we fill up those lines the DSL people will shut us down and we'll have to move to real T1 lines. That would at least triple our costs. I think it's a lot more than that, last I checked a fractional T1, around 400Kbits/sec, was $1000/month. Our way around this problem is to get you to do one "bk clone" and only "bk pulls" after that. That will transfer _only_ the data which has to be transferred, nothing else. Even that is a substantial amount when you multiply it all out by the number of people. We'll deal with that, we won't deal with full copies. I know Mvista offers rsync/ftp access and they're welcome to do so. They make (some) money off of Linux/PPC so they can justify it. I suspect, however, when they find out that FTP/rsync is filling up a T1 line and they have to buy more bandwidth, their management may raise a stink. Money is money, it's one thing to spend it when there is no other choice, it's quite another for people to be wasteful. -- --- Larry McVoy lm at bitmover.com http://www.bitmover.com/lm ** Sent via the linuxppc-dev mail list.
