does anybody have an incron based backup script?

[Arian Kuschki <arian.kuschki@googlemail.com>]

Hi all,
pretty much what I said in the subject: I thought about using incron to 
append files to a tarsnap archive whenever they are changed. Has anybody 
tried this?

And related to this, does tarsnap have the option at all to append files to an  
existing archive (like tar -r or tar -A)?

Cheers
Arian
