# Backup Postgresql Database from Docker

```

docker exec -t your-db-container pg_dumpall -c -U postgres > dump_`date +%Y-%m-%d"_"%H_%M_%S`.sql

```

Creates filename like dump_2023-12-25_09_15_26.sql

If you want a smaller file size, use gzip:

```

docker exec -t your-db-container pg_dumpall -c -U postgres | gzip > dump_`date +%Y-%m-%d"_"%H_%M_%S`.sql.gz

```

If you want even smaller file sizes use brotli or bzip2:

```

docker exec -t your-db-container pg_dumpall -c -U postgres | brotli --best > dump_`date +%Y-%m-%d"_"%H_%M_%S`.sql.br

```

or

```

docker exec -t your-db-container pg_dumpall -c -U postgres | bzip2 --best > dump_`date +%Y-%m-%d"_"%H_%M_%S`.sql.bz2

```

Restore your databases

```

cat your_dump.sql | docker exec -i your-db-container psql -U postgres

```
