How to backup and restore a whole /var/discourse app folder?

This is an excellent approach! Thank you!

One issue on restoration server.

./launcher logs app

2020-06-18 13:33:56.434 UTC [127] FATAL: data directory “/shared/postgres_data” has wrong ownership
2020-06-18 13:33:56.434 UTC [127] HINT: The server must be started by the user that owns the data directory.
./run: 3: echo: echo: I/O error
2020-06-18 13:33:57.448 GMT [128] LOG: skipping missing configuration file “/shared/postgres_data/postgresql.auto.conf”


That could be due to some missing tar options? Added -p and -s during extraction but didn’t help.

original server (outside docker):

ls -la /var/discourse/shared/standalone/postgres_data/

drwx------ 7 messagebus messagebus 4096 May 25 13:16 base

original server (inside docker (./launcher enter app)):

ls -la /var/lib/postgresql/10/main/

drwx------ 5 root postgres 4096 May 25 23:28 base


restoration server outside docker:

ls -la /var/discourse/shared/standalone/postgres_data/

drwx------ 7 messagebus messagebus 71 May 25 11:16 base

restoration server inside docker:

drwx------ 5 root postgres 41 May 25 23:28 base


./launcher rebuild app would fix it but that’s besides the point.

Any idea?
