I have a master backup system that rsync's with windows servers and does incremental backups with the --link-dest flag. Works great. Each day it looks at the previous day and only backs up what changes with hard links.
I have spun up another server that on a weekly basis I want to replicate off these backups and then take offline. My first attempt at just doing a basic rsync yielded a full array as instead of copying all the links it sync'd the files in each directory in their full size each and every time.
Right now I have:
rsync -acvlPE --rsync-path="sudo rsync" <user>@<host>:/backupdir /<localdir>
This seemed to work fine on the first run through. It pretty well duplicated what was on the orginating server.
THe issue came when I ran the command again the next day. It did a full sync all over again, not just sync'ing what changed in the source.
Any thoughts on how to handle this better?
