Come together with the global Drupal community in Rotterdam, 28 Sept – 1 Oct 2026. Sessions, contribution, connection, and Early Bird savings until 8 June.My scheduled backups are working fine. However, I have recently lost the ability to do manual backups. When I go to admin/content/backup_migrate and click "Backup Database" it will usually look like the page is reloading for a minute, then an HTTP 500 - Internal Server Error page will come up. Other times it will appear to work - the backup will start, but the final file size will not be right. For example, the backups in the scheduled backup are all consistently 11m, but the backups that I have actually downloaded manually range from 1m to 7m.
I used to be able to do manual backups fine. Could it be that the file size has become too large? Could it be incompatible with a specific module?

ronan commentedThat's probably either a timeout or you're running out of memory. Can you check your apache logs? Are there any fatal errors in there related to this? You can try increasing your php timeout or memory limit and see if that fixes it. Or if you're feeling brave, update to the 2.x dev branch of the module which handles timeouts much more gracefully (ie: it will still fail, but you'll get a helpful error).
Let me know if any of these things helps.
