Backups

So, it’s been another year and I’m getting better settled in to Linux. I’ve run through a lot of different window managers and desktop environments, like KDE, i3 and WindowMaker, before settling on DWM. Add to that more than a fair share of auxiliary programs to flesh out the experience and make things customized for me.

To that end, I’ve been trying to ensure that if anything should fail, I have a good backup to restore from. Enter Borg. It’s a command-line driven backup tool that not only compresses and encrypts the contents, but it de-duplicates it. This is fantastic for lots of little text files and the occasional photo set. The problem for me was, it was a lot of hassle feeding it all the options needed every time. Sure, I could alias it to make it simpler, but that still left a bit of work for me to do to get everything sorted, including un/mount the backup share, putting in a myriad of passwords, checking for number of incremental backups and pruning them so that I’m not dropping hundreds of gigabytes of useless, mostly similar backups (dedup’d or not) on my server, and on my offsite storage.

So, like most things on Linux, I glued all this together in a simple Fish Shell function. This allows me to just run a command (or add it as a user systemd timer) that backs everything I care about up, prunes and does all the drudgery of making a nice secure backup. Here’s my script/function that makes this all easier.

function my-backup -d "Mounts backup and runs borg"

	# Check for borg, first, bail out if it's not found
	if [ ! -x /usr/bin/borg ]
	    echo "Borg not found, please install before running this script."
	    exit 1
	end

	# Check to see if the repo pass is available. We use this to avoid
	# typing passwords all the time
	set -x BORG_PASSCOMMAND ""
	set -x CURRENT_DIR (pwd)

	# What to back up

	# Emacs
	set -a BACKUP_FILES /usr/share/emacs/site-lisp/default.el

	set -a BACKUP_FILES $MY_AUR_LIST $OFFICIAL_PACKAGE_LIST

	# Pacman package list backups, these are mine, the system will
	# (eventually) generate a full list at /etc/pkglist.txt
	echo "Exporting Pacman package lists"
	pacman -Qqem > $MY_AUR_LIST

	# Go home, for context
	cd ~

	# Check to see if the backup share is mounted, if not mount it
	if [ ! -d /mnt/backups/degruchy ]
	    echo "Mounting backup share to /mnt/backups/"
	    echo "You will need your password to do this."
	    sudo mount ...
	end

	echo "Trying to create a backup in /mnt/backups/degruchy with today's date and hostname."

	borg create --stats --progress --comment "New automated backup of critical stuff" --compression auto,lzma,6 /mnt/backups/degruchy::(date +%F)-(hostname) $BACKUP_FILES --exclude-from ~/.config/borg/exclude-file

	set -x IS_PHONE_PLUGGED (lsusb | grep -i "Apple" | wc -l)

	if [ $IS_PHONE_PLUGGED -gt 0 ]
	    ## TODO: The phone data is copied locally, first, probably a
	    ## good idea to check for available space, first.
	    echo "Looks like your phone is plugged in, backing that up, too..."
	    set -x PHONETEMP $HOME/.cache/temp/(date +%F)-nathans_phone
	    mkdir $PHONETEMP
	    idevicebackup2 backup $PHONETEMP
	    borg create --stats --progress --comment "Nathan's Phone backup" --compression auto,lzma,6 /mnt/backups/iPhoneBackups/::(date +%F)-nathans_phone $PHONETEMP
	    rm -rf $PHONETEMP
	end
	
	echo "Checking for backup prunability..."
	
	# Clean up old backups
	echo "Pruning..."
	borg prune --list --keep-daily 7 --keep-weekly 4 --keep-monthly 6 /mnt/backups/degruchy/
	borg prune --list --keep-daily 7 --keep-weekly 4 --keep-monthly 6 /mnt/backups/iPhoneBackups/

	echo "Unmounting backup. You may need your password again."
	sudo umount /mnt/backups
	echo "All done!"

		# Go back to where you were, if not already there
	if [ -d $CURRENT_DIR ]
	    cd $CURRENT_DIR
	else
	    cd ~

Goodbye CCAT

So, it’s ending all over again. This time I say goodbye to a really excellent organization known as CCAT. These last (almost) 2years have been a huge learning experience for me and something I’ll take with me as I move on.

I’d really like to thank the excellent non-profit clients we have herein Florida for being such a big reason that I got up every day. Places like United Way of Northeast Florida, Big Brothers Big Sisters of Northeast Florida, Family Foundations, Leadership JAX, Delores Barr Weaver Policy Center, Non-Profit Center of Northeast Florida and (of course) the Jessie Ball duPont Fund. Every day, these organizations and their volunteers and employees made my job one I truly enjoyed.

I also wanted to thank my excellent co-workers who, despite it all, helped me grow as a person and as an employee. I’m really fortunate to have had such patient and understanding people to work with and for. Their dedication to my own success, as well as our clients, is really just outstanding. I wish them all the best of luck in their future endeavors.

So long, and thanks for all the fish!
