rsync replicate existing rsync server data

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?

have you tried to use Windows deduplication? sometimes it is enabled and you may not notice it

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
