==================================================================== What is this? ==================================================================== This is a Bash program for backing up contents of one directory (source) into another (target). The full paths for the directories are assigned to variables source_dir and target_dir in the script. Assigning the correct paths to these 2 variables is the only thing a user needs to do to make the script work on their Mac. This program is mainly intended for backups to the iCloud drive. The Mac's default backup utility called Time Machine currently doesn't support backups to iCloud. ==================================================================== Important limitation ==================================================================== The program is known to error out if either one of the directories contains over 2-3 thousand items. This is because the bash arrays that hold the contents of directories get overwhelmed at runtime. ==================================================================== Example of typical use ==================================================================== Here is an example of a typical use of this program: You have a folder on your Mac where you keep important files, such as class notes or important spreadsheets, that you would like to be able to backup to your iCloud drive. Note, this works best for a small size directory with less than 2000 files or directories, not an entire home drive. For backing up your entire drive please use Mac's backup utility, Time Machine, to backup to a portable hard drive. The script will backup files in any sub directories. You can use this script to make regular backups of this directory to an iCloud directory with ease, by saving a copy of this script, making a quick customization for your environment, and then simply executing the script whenever you feel it's time to back things up. ==================================================================== How to execute this program? ==================================================================== 1. Download or clone this script ("backup.sh"), or copy and paste its content in a text file somewhere on your local machine, renaming it "somename.sh". 2. Using any text editor such as Sublime or Nano, change the value of 2 variables inside the script - "source_dir" and "target_dir", located around lines 10-15 in the script, to whatever paths you will be using. Source refers to the directory you want to backup, and Target refers to the directory you want to backup to. Normally, Source would be a directory on your machine and Target would be a directory on your iCloud drive. I provided examples in the script. 3. Execute the script by opening Terminal and running command: "bash backup.sh". Please note that if you are not in the same directory that the file is located, you will have to include the path in the command like so: "bash ~/scripts/backup.sh". Also note that if you changed the name of the file, you will have to provide that name in place of "backup.sh". ==================================================================== Legal information ==================================================================== The author of this program is Adilbek Madaminov.
