When you’ve completed the import process, delete the dump file from its storage location if it’s no longer needed. If you’re running Windows, you must use double-quotes. If you’re using a Unix-like operating system, make sure to use single quotes around the temporary S3 URL, because it can contain ampersands and other characters that confuse your shell. You must specify a database configuration variable to restore the database. Use the raw file URL in the pg:backups restore command: $ heroku pg:backups:restore '' DATABASE_URL -app example-appĭATABASE_URL represents the HEROKU_POSTGRESQL_COLOR_URL of the database you wish to restore to. Generate a signed URL using the AWS console: $ aws s3 presign s3://your-bucket-address/your-object

While Heroku PGBackups can download any backup files that are directly accessible through a URL, we recommend using Amazon S3 with a signed url.
Other backup formats result in restore errors. The pg:backups:restore command expects the provided backup to use the compressed custom format. If objects exist in a local copy of the database already, you can run into inconsistencies when doing a pg_restore. Load the dump into your local database using the pg_restore tool.
Read more about the supported options in the PostgreSQL documentation. Use any of the supported pg_dump options as needed, such as -schema or -table to create dumps of specific schemas or tables of your database. If you need a partial backup of your Heroku Postgres database or a backup in a non-custom format, you can use pg_dump to create your backup.įor example, to create a plain-text dump from your Heroku Postgres database: $ pg_dump -Fp -no-acl -no-owner mydb.dump $ heroku pg:backups:download -app example-app To export the data from your Heroku Postgres database, create a backup and download it: $ heroku pg:backups:capture -app example-app Capture and Download Backup with PGBackups

For databases that are larger than 20 GB, see Capturing Logical Backups on Larger Databases. Perhaps the biggest issue here is that Android isnt that reliable when it comes to backing up and restoring app data when compared to iOS. Contention for the I/O, memory, and CPU needed for backing up a larger database becomes prohibitive at a moderate load and the longer run time increases the chance of an error that ends your backup capture prematurely. In general, PGBackups are intended for moderately loaded databases up to 20 GB. As compared to the plain-text format, the custom format options result in backup files that can be much smaller. The resulting backup file uses the custom format option in pg_dump. PGBackups uses the native pg_dump PostgreSQL tool to create its backup files, making it trivial to export to other PostgreSQL installations. An alternative to using the dump and restore method of import/export if you have a Postgres instance on your local machine is to use the pg:push and pg:pull CLI commands to automate the process.
