Backup Your WordPress Site (Manually)
TL;DR – don’t use automated solutions. Do it properly and do it manually!
Create a temporary directory to work in:
mkdir backup-20200105 cd backup-20200105
Time to dump the MySQL database! It’s not that hard.
Quick note before you run this – this is assuming your MySQL installation authenticates via UNIX sockets. If you have password authentication I suggest moving away from it if your MySQL database is on the same server as your WordPress site. Less chance of things getting messed up and you don’t have to remember yet another root password that could be leaked.
sudo mysqldump --add-drop-table -u root wordpress > database.sql
If it prompts you for your sudo password, supply it. If it prompts you for your MySQL password, then you’ve done something wrong.
Now you need to copy the static files and what not. Run:
cp -a /var/www/example.com ./
-a flag tells the
cp program to copy over all attributes. It doesn’t always work, however. In my case it rewrote the
www-data user to
ericswpark. Nothing a simple
chown can fix, though!
Time to tarball the entire thing. Back out and then run:
tar -czvf backup-20200105.tar.gz backup-20200105/
You’ll get a neat tarball you can throw on Google Drive or something like that! Wasn’t that easy?
Get the tarball and unpack it:
tar -xzvf backup-20200105.tar.gz
Go inside, and then run:
sudo mysql -u root wordpress < database.sql cp -a example.com /var/www/
Restore permissions if required. Done!
