RSync Help

[Crothers]

Hey Guys,

I'm working on a backup solution, but I need a few ideas. I was hoping some of you could help me out, I can pay in E-Cookies.

Basically I want to use RSync as a backup solution of only altered files from a base install as so-

Base Install
/install
-/dir1
--file1
--file2
-/dir2
--file1
-/dir3
--file1
--file2
--file3

Lets say they add this-
/install
-/dir1
--newfile1
--newfile2
--file1
--file2
-/dir2
--file1
--newfile1
-/dir3
--file1
--file2
--file3
-/newdir1
--newfile1
--newfile2

Basically since I know the "Base Install" I want to only backup the new files/folders. So the only things rsynced would be this-

/backup
-/dir1
--newfile1
--newfile2
-/dir2
--newfile1
-/newdir1
--newfile1
--newfile2

I've been looking into --exclude, but it assumes I know what there is to exclude, where in this case I would not know. I would know what the base install is supposed to include though.

Any ideas?

Since you know the files that constututes your base install, you can use
--exclude-from=exclude_file
Where exclude_file is a text file which contains base install files
