Hi!
I need use rsync for incremental backup, but i need save that incremental
data on diferent directory, for example
I have a Full backup on directory ./FULL, and carpets for ./monday ... I
need to compare the sources with ./FULL and the diferents files save on
../monday .. but not in ./FULL
---------- -----------
SERVER A | | SERVER B |
---------- ------------
DATA + x ./FULL/DATA
<----with---rsync--> ./monday/x
Some can help me, using only rsync?
Thanks!

If you want hard-links to all the unchanged files to be put into "monday", use --link-dest=../FULL instead. If you want only changed files that don't appear in prior day dirs, you'll need to use 2.6.4 because it allows you to use multiple --link-dest or --compare-dest options, allowing you to only copy files that haven't been received yet (however, I recommend using --link-dest with multiple dirs, since it preserves the information on what version of the file was identical on that given day). ..wayne..

You should use --compare-dest=../../FULL instead (or just --compare-dest=/FULL, if appropriate). ..wayne..
