Bug Description

Please consider adding support for the nocache utility to minimize filesystem cache pollution from rsync and cp. Without this large rsync operations can trash the current filesystem cache and reduce responsiveness of the entire system.

For rsync and cp it could be used as a prefix command similar to ionice and nice. e.g. 'nocache rsync' and 'nocache cp'.

Another possibility (that I havent tried) for rsync might be be to use --rsync-path='nocache rsync'.

I'm not sure if prefixing backintime with nocache would be inherited by child processes.

Thanks

--rsync-path='nocache rsync' is only relevant for remote host.

BackInTime always use 'cp -aRl' which will just create hard-links. So only rsync need to run with 'nocache' to prevent floating cache. I added options to run local and remote rsync with nocache
