Is it possible to pipe the result of a mysqldump straight to rsync as the source argument?

Conceptually, I was thinking something like:

mysqldump -u root -p database_to_backup > db_backup_file.sql | sudo rsync -avz db_backup_file.sql

I've seen people pipe the result to mysql for their one liner backup solution, but I was curious if it was possible with rsync. You know--- cause rsync is magic :)

Thanks for your time!

Have you already tried it? :) – dezso Feb 25 '13 at 14:57

It's not clear exactly what you're trying to accomplish, but I'll take a couple of guesses and see how close I get.

If you're wanting to let rsync magically handle the difference between your local dump file and a remote dump file, you could just replace the | with && so that if mysqldump finishes without an error, then rsync will transfer the differences after the backup is complete, and if mysqldump fails, the synch won't happen.

On the other hand, if you're just wanting to transfer the dump file across the network and drop it somewhere other than the local machine, then this is an option:

mysqldump -u root -p database_to_backup | ssh 'cat > /var/www/db_backup_file.sql'

...where /var/www/db_backup_file.sql is a path on the remote machine.

Or if you wanted to save it both locally and remotely at the same time:

mysqldump -u root -p database_to_backup | tee db_backup_file.sql | ssh 'cat > /var/www/db_backup_file.sql'

As someone completely different who just got this question as his first google result, I was looking because of the --bwlimit option on rsync – Izkata Oct 19 '15 at 19:25
