history lost problem

Hello,

We in the copany use subclipse with the latest svn (server). There is often happened, that
one guy move or just copy (from filesystem) to eclipse a file, and replace the original
file, in the checked out repository. Both action delete the old file, and create a same
named file, and start a new history.

My question is, it is possible to implement an svn move in eclipse not to loose the
history of a file?

When I replace a file (with copy-pase) it is possible to insert just the file's context,
and not delete the old, and create a new file with the same name and therefor not to loose
the history?

In Subclipse I aslo did not find any possible way to list the old logs, for example see
the log of a deleted file. e.g. "svn log -r0:666 deleted.file.txt"
