$ cd backup-mastodon
$ cp .env.backup-mastodon.sample .env.backup-mastodon
$ cp backup-mastodon.d/.env.backup-postgresql.sample backup-mastodon.d/.env.backup-postgresql

$ vi .env.backup-mastodon
$ vi backup-mastodon.d/.env.backup-postgresql
$ vi backup-mastodon.d/.env.backup-redis

test run

run as root.

# ./backup-mastodon.sh

if succeeded, 3 files are created in directory which is defined by environment variable ${BACKUP_DEST_DIR} in /.env.backup-mastodon.

periodical backing up

create drop-in file in /etc/cron.d.

03 04 * * * root /bin/bash /path/to/backup-mastodon/backup-mastodon.sh > /tmp/backup-mastodon.out 2>&1

or edit root's crontab.

03 04 * * * /bin/bash /path/to/backup-mastodon/backup-mastodon.sh > /tmp/backup-mastodon.out 2>&1

note

if you use tcp/ip to connect to postgresql, put a file .pgpass in directory /root. (such as if postgresql is running on another host)

<host>:<port>:<db name>:<user>:<password>

for example:

127.0.0.1:5432:mastodon_production:mastodon:mastodonpassword

note2

Also even if using tcp/ip to connect to postgresql, these scripts will work correctly. MAYBE.
