BookStack Backup Script

This is a simple BookStack backup script, to dump the database, copy uploaded files, and zip it all up into a timestamped archive. This is designed for an on-system install, not a docker setup. Database credentails are automatically read from your BookStack config.

This script will copy uploads before zipping, so you'll need more free space on your system than your BookStack directory already consumes.

Usage

1. Copy the script down to a file (bookstack-backup.sh).
2. Tweak the configu variables at the top of the script.
3. Make the script executable (chmod +x bookstack-backup.sh).
4. Run the script (./bookstack-backup.sh).

bookstack-backup.sh

#!/bin/bash

# Directory to store backups within
# Should not end with a slash and not be stored within 
# the BookStack directory
BACKUP_ROOT_DIR="$HOME"

# Directory of the BookStack install
# Should not end with a slash.
BOOKSTACK_DIR="/var/www/bookstack"

# Get database options from BookStack .env file
export $(cat "$BOOKSTACK_DIR/.env" | grep ^DB_ | xargs)

# Create an export name and location
DATE=$(date "+%Y-%m-%d_%H-%M-%S")
BACKUP_NAME="bookstack_backup_$DATE"
BACKUP_DIR="$BACKUP_ROOT_DIR/$BACKUP_NAME"
mkdir -p "$BACKUP_DIR"

# Dump database to backup dir using the values
# we got from the BookStack .env file.
mysqldump --single-transaction \
 --no-tablespaces \
 -u "$DB_USERNAME" \
 -p"$DB_PASSWORD" \
 "$DB_DATABASE" > "$BACKUP_DIR/database.sql"

# Copy BookStack files into backup dir
cp "$BOOKSTACK_DIR/.env" "$BACKUP_DIR/.env"
cp -a "$BOOKSTACK_DIR/storage/uploads" "$BACKUP_DIR/storage-uploads"
cp -a "$BOOKSTACK_DIR/public/uploads" "$BACKUP_DIR/public-uploads"

# Create backup archive
tar -zcf "$BACKUP_DIR.tar.gz" \
 -C "$BACKUP_ROOT_DIR" \
 "$BACKUP_NAME"

# Cleanup non-archive directory
rm -rf "$BACKUP_DIR"

echo "Backup complete, archive stored at:"
echo "$BACKUP_DIR.tar.gz"

Thanks. Once I add the time stamp to the bookstack.zip file it works. I just need to figure out how to rotate the backups to avoid the database filling up the disk.

Thanks again.

a simple solution to that: find /sicherung/bookstack/ -mtime +31 -name bookstack_*.zip -exec rm -f {} \;
this will delete all files older than 31 days.

Thanks Man-in-Black for that. At the moment I just use a bash script to automatically delete the zip file first, then run the docker backup script to create a new bookstack.zip, so that the hyperbackup program on my synology can pick up the bookstack backup files.

Your script is a much better and more elegant way of doing this file rotation. I will try to adapt to my system.
Thanks again for that. This is much appreciated.
