Zimbra

Hi all,

I am planning to move my Zimbra install to new hardware this week. I found JHolder's blog on this subject:

http://www.zimbra.com/blog/archives/...er_server.html

And I get to part 4 (step 2) and something doesn't look right.

As Root: rsync your backup to the new location: rsync -avr /mnt/migration/zimbra /opt/

Shouldn't this read: rsync -avr /mnt/migration /opt/zimbra

The source should be /mnt/migration and the destination should be /opt/zimbra? (the directions look like they have /opt/zimbra backwards)

Also, shouldn't there be a space between the source & destination?

I'm still fairly new to Linux so this might just be me...

Thanks,
Rob

Yup there is a space in that, the font may just be tricking you

There's spaces between all parts, as I've indicated with [] below:
rsync[]-arguments[]src[]dest

With rsync these mean the same thing:
rsync -av /src/foo /dest
rsync -av /src/foo/ /dest/foo

A trailing slash on the source changes behavior to avoid creating an additional directory level at the destination. You can think of a trailing / on a source as meaning "copy the contents of this directory" as opposed to "copy the directory by name", but in both cases the attributes of the containing directory are transferred to the containing directory on the destination.
In other words, for all intensive purposes, each of the above commands copies the files in the same way. Archive mode, ensures that symbolic links, devices, attributes, permissions, ownerships, etc remain intact.

Edit/Extra info:
You don't need -r because -a already includes -rlptgoD
-d (small d) is close to -r but works on directories in a little different way (if you include -a or -r then -d is ignored)
-R (big R) is used for relative paths
I sometimes prefer to use rsync -avHK (which is hard-links & keep-dirlinks receiving side; there's also copy-dirlink from the sending side)
Including the --delete option gets rid of files in the dest folder that don't exist at the src. Very useful if you don't clear your dest each time first, which is normal if your doing this daily because you don't want to take a lot of time to backup each time, just the changes.
