tarsnap-backup-osx

A shell script and launchd config file to run daily backups on specified directories and upload them to tarsnap.

To use:

• Get a tarsnap account and set it up
• Make the backup executable
• Change the value of the array:string in the org.btb.backup.plist file to the location of your backup. Use the full path name.
• Place org.btb.backup.plist in your ~/Library/LaunchAgents directory
• If you change the name of the plist file, make sure that Label:string in the file matches
• Edit the $DIRS variable in the shell script to specify what directories you want to back up. The format is <directory>:<name>. This means that it will back up directory <directory> and name the archive YY-MM-DD-<name>-HHMM.

Commands:

• backup list Lists the most recent successful backup dates

Other features:

• The shell script has a $SSIDHOME variable that lets you set the SSID name of your home network and will exit out of the script if you're on any other network.
• Logs are written by default to ~/logs/backup.log

Issues:

• The script strips white space in directories such as "/Google Drive/". To fix, I create a shadow directory that is a symlink to the real directory (e.g., .gdrive/ -> /Google Drive/). You can do this with ln -s ~/Google\ Drive/ .gdrive
• Use full pathnames! Using something like ~/directory can lead to problems. You're much better off to use /Users/<username>/directory.
