How to backup database?

[Truong Vu]

Hi,

When I try to backup remote database, I got stuck with the following issue:

$ bundle exec cap production db:backup --trace
** Invoke production (first_time)
** Execute production
** Invoke load:defaults (first_time)
** Execute load:defaults
** Invoke db:backup (first_time)
** Execute db:backup
** Invoke db:backup_name (first_time)
** Execute db:backup_name

Please help me, thank you very much.

Hi @vukhanhtruong can you send me over the output from the command too?

[Truong Vu]

Thanks for your support. That's exactly what I get when run the command above. Nothing more.
Am I missing something?

** Invoke production (first_time)
** Execute production
** Invoke load:defaults (first_time)
** Execute load:defaults
** Invoke db:backup (first_time)
** Execute db:backup
** Invoke db:backup_name (first_time)
** Execute db:backup_name

@vukhanhtruong No problem, happy to help! Can you let me know what the output is without the --trace flag.

[Truong Vu]

@lukewhitehouse It shows nothing.

[Luke Whitehouse]

@vukhanhtruong strange! Have you filled in your database details within your config/database.yml file? In addition, are your server details filled in at config/deploy/production.rb?

[Truong Vu]

Yes, I did. I can deploy to production. Everything is working fine, except these commands regarding to DB.

[Luke Whitehouse]

@vukhanhtruong And when you go to the root of your local codebase, you do not see the .sql export of the live database?

[Truong Vu]

Yes, there is no sql file.

[Truong Vu]

Also, I can remotely access database from locally. I really appreciate your support. Thank you.
