For now it seems like the diff tool should have some presets for backup/restore 
operations. eg you want your work data backed up daily and to a different 
location than tags for your multimedia lib which is backed up weekly.

Looks like a collection of small scripts + some GUI. I wish I had time to do 
this but unf I'm totally occupied with libstreamanalyzer atm :(

It's better to only backup user-generated content. This means you get to 
backup MBs instead of GBs. Imagine someone telling nepomuk to index KDE repo 
or something equally crazy(but possible) like this.

Of course indexing GBs of data doesn't apply to redland :)
