Backup the data

Everything is up and running now. Great! 🎉

What's left is regular backup of the user data in case server breaks down.

One of the options

My server is a bit specific. I use rsync + stunnel to securely send data to a backup ftp server. Note: rsync on its own sends data insecurely. Here's an instruction I used (in Czech).

My backup script performs the work in /home/[user]/[path-to-backup]/ folder, and it looks like this:

backup.sh

# archive the data folder
tar -czf /home/[user]/[path-to-backup]/$PERIOD-backup.tar.gz /home/[user]/www/[projectname]/data/
# encrypt the archive with gpg
gpg -r [public-key-identifier] --trust-model always --encrypt /home/[user]/[path-to-backup]/$PERIOD-backup.tar.gz
# send the encrypted archive over to remote server with rsync + stunnel
rsync -r /home/[user]/[path-to-backup]/$PERIOD-backup.tar.gz.gpg rsync://s21445@localhost/s21445/[path-to-remote-backup]/ --password-file=[/path/to/password-file.pass]
# clean up
rm /home/[user]/[path-to-backup]/$PERIOD-backup.tar.gz /home/[user]/[path-to-backup]/$PERIOD-backup.tar.gz.gpg

I use cron to run this script regularly:

# m h  dom mon dow command
30  01 *   *   *   PERIOD=daily /home/[user]/[path-to-backup]/backup.sh
35  02 *   *   2   PERIOD=weekly /home/[user]/[path-to-backup]/backup.sh
40  03 5   *   *   PERIOD=monthly /home/[user]/[path-to-backup]/backup.sh

This stores 3 backups from different times. You can specify your own days and times of backup.

All this is done as [user]. Not root.

You can figure out your own way. Make sure the data are sent and stored securely, and that you have a way to access and decrypt them in case something goes wrong!

Thank you for reading and trying this out.

That's all for now. I hope your server is running to your satisfaction. I may add some further instructions, like

If you find any mistakes, or have ideas for improvement, please open an issue on GitHub.

Best wishes!
