Question
"Waiting for backup lock" when altering table in managed MySQL database
- Posted on January 17, 2023

Asked by robjbrain
I’m trying to run a migration and the process for an alter table command is locked with show processlist giving its state as Waiting for backup lock
The text seems kind of self explanatory, there must be a backup happening.
Unfortunately I can’t see anything in the control panel that refers to backups, such as what time they happen, logs of how long they take or anyway to be able to identify if one is happening.
How can I change when backups occur?
How can I know if a backup is running before attempting to run some code so I don’t hit this problem again?

Hi there,
To verify if this was indeed a backup, you can use the DigitalOcean API and send a GET request to
/v2/databases/$DATABASE_ID/backupswhich will return a list of your database backups and the time they were created:https://docs.digitalocean.com/reference/api/api-reference/#operation/databases_list_backups
What you could also do is to change your maintenance window by sending a PUT request to
/v2/databases/$DATABASE_ID/maintenance:https://docs.digitalocean.com/reference/api/api-reference/#operation/databases_update_firewall_rules
Hope that this helps!
Best,
Bobby
