### Local

# Backup Immich database
docker exec -t immich_postgres pg_dumpall --clean --if-exists --username=postgres > "$UPLOAD_LOCATION"/database-backup/immich-database.sql
# For deduplicating backup programs such as Borg or Restic, compressing the content can increase backup size by making it harder to deduplicate. If you are using a different program or still prefer to compress, you can use the following command instead:
# docker exec -t immich_postgres pg_dumpall --clean --if-exists --username=<DB_USERNAME> | /usr/bin/gzip --rsyncable > "$UPLOAD_LOCATION"/database-backup/immich-database.sql.gz

### Append to local Borg repository

borg prune --keep-weekly=4 --keep-monthly=3 "$BACKUP_PATH"/immich-borg
borg compact "$BACKUP_PATH"/immich-borg


### Append to remote Borg repository
