Why?

I'm managing my own server, and I wanted to have a simple and easy tool to backup my database and all VirtualHost files, and to save them into a remote server with cronjob.

What This Script Does

This script does some simple tasks:

The script dumps all of your MySQL databases individually.
The script backs up all of your Web files (e.g: root path of all of your virtual hosts).
The script compresses your web-root and databases to a single archive.
The script uploads the compressed archive into a folder in your Dropbox account, Amazon S3 bucket, Mega.nz or to a WebDav solution such as OrnCloud/NextCloud Server.
If the method is set to dropbox, The script makes sure that you always have the newest Dropbox-Uploader script.
After the upload, the script cleans up the temporary files (dumps, the archive itself).

You may easily add this script to your crontab, and just forget about it 😄

Requirements

curl - To download the .backmeuprc file, Dropbox-uploader script and to upload the backup to Dropbox or to WebDAV.
mysql (cli) - To list databases.
7z (cli) - To list compress backup if compression is set as 7zip, or tar (cli) if compression is set as tar.
mysqldump - To dump databases (in most cases, it comes with mysql cli).
aws-cli must be installed and configured if the method is set as s3.
mega-cmd (the mega-put command is used that comes with the package) must be installed and configured if the method is set as mega.

Installation

Run these commands first:

curl -s https://raw.githubusercontent.com/Ardakilic/backmeup/master/backmeup.sh -o backmeup.sh
curl -s https://raw.githubusercontent.com/Ardakilic/backmeup/master/.backmeuprc -o ~/.backmeuprc
chmod 600 ~/.backmeuprc

Now, edit the configuration values as stated here.

Make the files secure, executable and only accessible by your root user and group (or the user you'd like the script to run):

chown root:root backmeup.sh #or any user and group who will run the script or with cron
chown root:root ~/.backmeuprc #or any user and group who will run the script manually or with cron
chmod 400 ~/.backmeuprc #Only readable by owner, and is read-only. To make it writable, change to 600 on demand
chmod +x backmeup.sh

(Suggested) Copy or move the script into one of the PATHs as stated here.

Configuration Values

After downloading the script, before running, you must edit your configuration values found in ~/.backmeuprc.

On-the-fly Configuration

You can set various configuration values on the fly. Here are some full featured examples:

backmeup -tz "Europe/Istanbul" -dbh localhost -dbu root -dbpass "rootpass" -dbp 3306 -f "/usr/share/nginx/html" -b "/tmp" -bf=my_backups -c 7z -7zcp "p4ssw0rd" -m s3 -s3bn my-aws-bucket -wdu "webdav-user" -wdp "webdav-password" -webdav "https://nextcloud-host.com/remote.php/webdav/"

Or like this:

backmeup --timezone="Europe/Istanbul" --database-host="localhost" --database-user="root" --database-password="rootpass" --database-port="3306" --files-root="/usr/share/nginx/html" --base-folder="/tmp" --compression="7z" --7-zip-compression-password="p4ssw0rd" --backup-folder="my-remote-backup-folder" --webdav-user="webdav-user" --webdav-password="webdav-password" --webdav="https://nextcloud-host.com/remote.php/webdav/"

None of these are mandatory, you can just use any of these however you want, and even mix together!

Usage

Execute the configured script:

./backmeup.sh #or "backmeup" directly if it's in your PATH.

If this is the first attempt to running and method is set to dropbox, Dropbox-Uploader will ask for an APP key and secret. You should create an application, provide these values and click on provided authorization link (Don't worry, the Dropbox-uploader has a nice wizard which guides you, can't be easier). After you've authorized, re-run the script using ./backmeup.sh
If everything went well, in a couple of minutes, you should see your database and files copied into the remote server.

Important Notice

This script saves MySQL password (any user which can show and dump (all) databases will suffice actually) inside, but it's only accessible by its owner and cannot be read by anyone else. In any ways, use it at your own risk. I'm not holding any responsibilities for any damage that this script may do (which shouldn't).

Additional Notes

You can also copy the script to one of your PATHS, such as /usr/local/bin/backmeup and run from there directly. This is suggested
