I'm running some backups using rsync, it seems to be spawning multiple copies of itself:-

Most likely this is rsync creating worker threads during I/O operations, which under linux appear as separate processes. They *appear* to be doing the same thing but you can't tell unless you connect a debugger to each and take a stack trace :)
Yes, I guess it must be something like that. Trouble is that they're taking far too long and don't finish before then next one starts (24 hours later) and then we've really lost it!
