Best way to fully backup a WordPress site??
 

Any help/hints is much appreciated :) ...

Don't know. I have 300 of the damn things spread over 4 servers.
I didn't back up for years.

If you have cPanel powered hosting - just backup the entire account.

Otherwise use All-in-One WP Migration plugin. This can easily backup and restore entire WP site. It can backup to File (zip), remote FTP, Dropbox, Google Drive, Amazon S3, OneDrive, Box... Amazing plugin and super easy to use...

Space is an issue.

That was truly helpful! Thanks :)!

Use a cron job with tar and mysqldump to back up and dump everything nightly. If space is an issue, use a tool like rsync to store incremental backups on a remote storage location.

Once you set it up, it's entirely automated every single night and you can certainly do it for multiple servers (rsync can handle numerous servers, but best to set up keys for it).

Similarly with upgrades. You can store all your plugins and themes on a single location and then just use rsync and wget / cron to download a fresh copy of wordpress each night, and push it out to your existing sites, regardless of server. Same with plugins and themes. This will ensure you always have the freshest files each day.

To that end, you'd either need ssh access, the ability to create cronjobs and, ideally, a bash file that can execute all the stuff you want to do via cronjob, or you'd need to ask your host to set it up for you. It's quite straightforward.

https://updraftplus.com/ does a good job.

If you are using Cpanel you can download all the files in a zip. Updraftplus is a great software to use too.

i use plugins like this https://en-au.wordpress.org/plugins/wp-exporter/
And just save the main index php files header and footer etc the rest can be created click of button on new directory in a flash. (one click installs)

I use automysqlbackup which makes daily,weekly,monthly mysql database backups of all my Wordpress databases and then I rsync /var/www to my backup servers.

Backup -- for what?

Site disruption/crisis use the plugin

Server failure use rsync and mysqldump to a remote back up.

I use this plugin too.
It works great!

Thanks, guys :thumbsup!
