Hi, I found it, there exist glastree which is available from ports.
Nice small "poor man's" backup as the author qualifies, though makes incremental backup through hard links: # if yesterday does not exist or today is newer, copy the file # else hard link the file to yesterday Ports: http://ports.su/sysutils/glastree Source: https://github.com/jeremywohl/glastree You can simply run it from crontab and even setup a short time daily and long time monthly or what ever else suits best through running the utility with different configurations from multiple crontab lines (daily, monthly, etc ...) glastree-1.04p0 – poor man's daily snapshot The poor man's daily snapshot, glastree builds live backup trees, with branches for each day. Users directly browse the past to recover older documents or retrieve lost files. Hard links serve to compress out unchanged files, while modified ones are copied verbatim. A prune utility effects a constant, sliding window. Satoru Takabayashi has written a similar program, in Ruby, pdumpfs. Inspired by Plan9, of course.
