| 5 | 3 | Viacheslav Anzhiganov | ```shell |
| 6 | 1 | Viacheslav Anzhiganov | CID=$(docker ps -f name=<container_name> -q) |
| 7 | 4 | Viacheslav Anzhiganov | DBN=db |
| 8 | docker exec -t ${CID} pg_dump -c -U postgres ${DBN} > dump_${DBN}_`date +%Y-%m-%d"_"%H_%M_%S`.sql |
||
| 9 | ``` |
||
| 10 | |||
| 11 | ## Backup all |
||
| 12 | |||
| 13 | ```shell |
||
| 14 | CID=$(docker ps -f name=<container_name> -q) |
||
| 15 | 3 | Viacheslav Anzhiganov | docker exec -t ${CID} pg_dumpall -c -U postgres > dump_`date +%Y-%m-%d"_"%H_%M_%S`.sql |

| 17 | |||
| 18 | Creates filename like dump_2023-12-25_09_15_26.sql |
||
| 19 | |||
| 20 | If you want a smaller file size, use gzip: |
||
| 21 | |||
| 22 | ``` |
||
| 23 | docker exec -t your-db-container pg_dumpall -c -U postgres | gzip > dump_`date +%Y-%m-%d"_"%H_%M_%S`.sql.gz |
||
| 24 | ``` |
||
| 25 | |||
| 26 | If you want even smaller file sizes use brotli or bzip2: |
||
| 27 | |||
| 28 | ``` |
||
| 29 | docker exec -t your-db-container pg_dumpall -c -U postgres | brotli --best > dump_`date +%Y-%m-%d"_"%H_%M_%S`.sql.br |
||
| 30 | ``` |
||
| 31 | |||
| 32 | or |
||
| 33 | |||
| 34 | ``` |
||
| 35 | docker exec -t your-db-container pg_dumpall -c -U postgres | bzip2 --best > dump_`date +%Y-%m-%d"_"%H_%M_%S`.sql.bz2 |
||
