Postgres - database backup
7 points
In this short article, we would like to show how to make Postgres database backup from the command line under Linux.
Quick solution:
xxxxxxxxxx
1
pg_dump -h localhost -p 5432 -U my-username -W my-database > /path/to/backup.sql
Note: command will ask us to type the current username password.
To include SQL commands to clean (drop) databases before recreating them, use the following command (-c
parameter):
xxxxxxxxxx
1
pg_dump -c -h localhost -p 5432 -U my-username -W my-database > /path/to/backup.sql
Where:
-c
causes adding database clean queries to the generated dump,localhost
and5432
should be used according to Postgres server address (host
andport
),my-username
should be replaced with current database credentials,-W
causes displaying propmpt to typemy-username
s' password,my-database
indicates copied database,/path/to/backup.sql
should be replaced with destinated backup file location.
Note: do not forget to check if Postgres is installed or run the installation command:
sudo apt install postgresql postgresql-contrib
