Backup
You can dump the entire PostgreSQL database to a zipped file with the combination of the pg_dumpall command and gzip. The pg_dumpall command is executed as the user postgres, by using the sudo command and the -u switch. It is separated from the gzip command with the pipe symbol.
This command can be automated to run on a regular basis using the standard cron tool on your server.
It is recommended to use an incremental backup technique to synchronize the your LibreTime track library with a backup server regularly. (If the backup server also contains an LibreTime installation, it should be possible to switch playout to this second machine relatively quickly, in case of a hardware failure or other emergency on the production server.)
Two notible backup tools are rsync (without version control) and rdiff-backup (with version control). rsync comes preinstalled with Ubuntu Server.
Note: Standard rsync backups cannot restore files deleted in the backup itself
#/bin/bash
# Replace /backup with backup folder location!
# Used for backing up the media library
sudo rsync -aE --delete --info=progress2 /srv/airtime/stor/ /backup
# Used for backing up the database
sudo -u postgres pg_dumpall | gzip -c > libretime-db-backup.gz
sudo mv libretime-db-backup.gz /backup
# Write date/time of backup to file
date >> /backup/datelog.txt
Restore from a Backup
When restoring a production database on a cleanly installed LibreTime system, it may be necessary to drop the empty database that was created during the new installation, by using the dropdb command. Again, this command is executed with sudo as the user postgres:
sudo -u postgres dropdb airtime
This dropdb command above is necessary to avoid 'already exists' errors on table creation when overwriting an empty LibreTime database in the next step. These errors might prevent some data from being restored, such as user account data.
To restore, first unzip the backup file with gunzip, then use the psql command as the postgres user:
gunzip libretime-db-backup.gz
sudo -u postgres psql -f libretim-db-backup
You should now be able to log in to the LibreTime web interface in the usual way.
For safety reasons, your regular database backups should be kept in a directory which is backed up by your storage backup tool of choice; for example, the /srv/airtime/database_backups directory. This should ensure that a storage restore can be made along with a matching and complete version of the LibreTime database from the day that the storage backup was made.
