  1. An other hint that I have noticed: why do you share the ssh authentication file for root instead of your alternative user in your tutorial?

  2. Hey Tarunika, first thanks for your great tutorial.

    Anyways does your solution only permanently synchronize the two folders? I think that’s not what I need. What I need are daily and weekly backups.

    Maybe I can use your solution and modify it so that before synchronization the latest backup is copied to an other directory.
    But in this case I were resulting in duplicated disc usage.

    This is from around 1999 but still the very best rsync tutorial I’ve ever read.

  6. How to backup on real time ?? I mean a file is created on folder and it needs to be moved in to another folder. Is that possible using rsync. I tried adding cron job with –remove-source-files but to no avail.

  7. xicoloco says:

    every time i run the sync he copy everything or just what changed ?

    and he delete wuat is not there tooo ?

  8. Troy Rose says:

    A couple of things.

    What are the benefits in terms of security of running rsync as root when all you are doing is replicating apache/httpd user files?

    Also, if your backup up web server is compromised, then the attacker now has complete access to your main webserver as root.
