Phase 3A - Differential Backup

— Dale Sinder and Steve Zoppi 25/04/18

After each significant milestone, it is a matter of good practice to perform a checkpoint backup of the changed files. In Phase 0 - Prepare Work Environment, the process for creating a cdc.io Cluster Backup was one of the tasks. Our objective in this phase is to establish a baseline git repository onto which this, and future changes, can be projected.

Because we have not made a change to Cluster Backup folder yet, it is an appropriate time to ensure that there is a baseline.

1. If it hasn't been done already, create a git repository at the cdc.io backup target directory.
   1. From the command line, enter the backup target directory location.
   2. Initialize the repository using the git init command
   3. Create a .gitignore file with the line /binary* in that same backup target directory location. This will exclude the PLATO Binary packs from being included in the repository.
   4. Add all other files and commit to the main branch. This will take a while.
2. Perform the incremental backup using the cdc.io c.backup command.

3. Once the backup is complete, verify that the changed files were detected as expected by issuing the git status command and observing the output:

   1. NOTE: The following files will always change with each backup:
      1. */Back_Info
      2. */BackDir
      3. Do not add these to .gitignore because they are important parts of the backup structure.
   2. Use the git add . command to add the Untracked files.
   3. Verify that they have been added by issuing another git status command:
