backing up files

backing up a local Git repository

Note

• foobar represents the name of the relevant Git repository to be backed up.
• /foo/bar/baz/foobar represents the directory containing the relevant Git repository to be backed up.
• foobar.bundle represents the intermediate Git bundle to be created during the course of backing up the relevant Git repository.
• /baz/bar/foo/foobar represents the directory containing a backup of the relevant Git repository.

Use cd "/foo/bar/baz/foobar" && git bundle create "/tmp/foobar.bundle" --all && git clone "/tmp/foobar.bundle" "/baz/bar/foo/foobar" to back up Git data, excluding any unstaged changes. Then use rsync -c -r -s -t -v --progress --exclude="/.git/" --exclude="/.gitignore/" "/foo/bar/baz/foobar/" "/baz/bar/foo/foobar"

Additional option

In rsync, the -n option enables a dry run, producing information on how the backup would be performed without making any changes to the directory containing a backup of the relevant Git repository.

explanation

Note

This is an incomplete explanation.

• The -c option enables the checksum-based file skipping.
• The -r option enables recursion.
• The -s option disables space-splitting.
• The -t option preserves file modification time.
• The -v option increases verbosity.
• The --exclude="/.git/" and --exclude="/.gitignore/" options exclude the .git directory and .gitignore file.
• The --progress option enables the displaying of transfer progress.

prior work

• The bulk of the rsync portion of the script was generated by grsync.
• The method of using git-bundle was introduced to me by an answer to “Backup a GitHub repository” on Stack Overflow by VonC and an answer to “How to backup a local Git repository?” on Stack Overflow by VonC.
• The method of using git-clone was introduced to me by an answer on Stack Overflow by fbicknel.
