I'm triyng/testing rsnapshot in my Ubuntu desktop to make incremental backups from a remote server to my desktop.
I use a custom config file where I set retain alpha 7
I executed rsnapshot -V -c /path-to/rsnapshot-my1.conf alpha and the backup was successful to the directory alpha.0 (17GB)
After some hours I executed it again and got another full backup at directory alpha.0 and the previous one was rotated (moved) to alpha.1
For the time the second run took to complete I see rsync made its job and only downloaded new or changed files.
But rsnapshot first duplicated the alpha.0 directory to alpha.1 and then run rsync on alpha.0.
So I get large unnecessary amount of duplicated data (triplicated, and so on).
Is it possible to have a mirror backup directory and rotation directories only contain changed or deleted files/dirs?
Update
I realized that "duplicated" files are hard links.
Anyway I would like to have what I asked, if possible.
It's a bit confusing seeing some new wiki docs naming retain hourly 24 retain daily 7... and my default config file has retain alpha 6 retain beta 7...
