Simple backup and versioning script for novice Windows users. Uses Git for Windows.

backup_via_git.sh

# The only required setting is DATA_ROOT. It must be a valid
# Git repository (git init'ed). You need to configure a name
# and an email to be used as commit author info. You also need
# to configure a remote named "origin" for this repository.
# A branch "master" is assumed to exist. For repositories with
# large binary files, you may want to change the following Git
# settings (probably only locally, for the current repo):
#
#   core.autocrlf=false
#   core.compression=0
#   core.loosecompression=0
#   pack.compression=0
#   pack.window=0
#
# If you've just set up Git, don't forget to set the committer info:
#
#   git config --global --add user.name "Some One"
#   git config --global --add user.email [email protected]
#
# On Windows, using MSysGit (Git for Windows):
# * Copy the "Git Bash" shortcut somewhere
# * Edit the "Target" property of the shortcut and paste the following:
#   C:\Windows\SysWOW64\cmd.exe /c ""C:\Program Files (x86)\Git\bin\sh.exe" --login -c '/C/Data/backup.sh'"
# * Just be sure to modify the "/C/Data/backup.sh" script to ensure
#   it points to the location where you've saved this file
#
# You may want to make the same settings at the remote repo too.
# Happy backing up!
