We use Ubuntu Server (14.04) as file server. As backup solution we use "Back in Time". I have a general question about making backups, since we are having problems with the folder names from time to time.

For example: Our main folder is called "CUSTOMERS" and is about 4TB large. If someone accidentally renames this folder to "CUSTOMERS1" (just as an example) the backup makes a complete new backup for this new directory.

I know that is what the backup is supposed to do but is there are smart way to avoid these problems?

  • Would it be an option to change permissions of that folder so no one can rename it by accident anymore? – Germar Jul 2 '15 at 11:17

Change the ownership of CUSTOMERS parent folder to root and remove write permissions for other users. This way no one can rename the folder by accident anymore.

sudo chown root:root /path/to/parent
sudo chmod 755 /path/to/parent
