rsnapshot "apt-get install rsnapshot" is a collection of perl scripts that use rsync and has 3 levels of decimation, arbitrarily named, hourly, daily, weekly the intervals are usually activated by cron tasks but can also be run manually
for example, hourly could be set run every 12 hours and keep 7-8 days in rotation daily could be set to run once a week for 6 weeks in rotation weekly could be set to run once a month Weakness: changes are only captured at the scheduled "hourly" snapshot times it uses hard links so each unique version of a file is only copied once a file is never moved or freshened once copied so it is more vulnerable to bit rot for best results the 3 decimation level runs should not overlap (collision interactions can be complex) the rule of thumb is that when used in depth, the backed-up volume is about 2X the base size has a number of options. something close to default recommendations in config file is pretty good see man rsnapshot For my needs, simple ryncs in a script give me a "poor boy's" rsnapshot Chris On 14-04-25 09:23 PM, Shawn Grover wrote: > I use rsync in via a bash script.
