I have a full SSH backup, and it is scheduled to run daily. When I run the backup manually (by going to the scheduled backup page, opening the backup, and choosing backup now) it works great! When the backup is run by cron, though, it does not work.
At the scheduled time it logins into via SSH and creates the new backup folder. Then the backup process appears to take some time creating the backup archives. At some point there after the process fails and nothing is recorded in Backup Logs.
Where should I look next?
Update: confirmed that backup also works when using the “backup in background” option from the UI. It only fails when initiated by cron.
