问题
I have been using PG Backups add-on recently and everything has worked fine, however this morning the backup process triggered at 10:00 A.M. in the morning generating some blocks and timeouts in my application.
Is there a way to specify the schedule of the backups made with this add-on? I've been searching and haven't found anything specific.
回答1:
Use Cron for Manual Backup Scheduling
Heroku gives you two types of backups: automated and user-initiated. Each plan has a different number of daily, weekly, and manual backups that are retained. You can't control when the automated backups occur with PG Backups Auto, but you can use cron to trigger a "manual" backup at any time.
For example:
# Trigger a "manual" backup every four hours.
0 */4 * * * source $HOME/database_credentials; heroku pgbackups:capture
See Creating a Backup for more information about using the pgbackups command.

No, there is no way to do it currently, aside from using an external process to fire the calls.
An email to support might reveal more.

While the original question is old, Heroku does have a schedule option for PGBackups now:
