I'm continuing from the progress that was made here:
To summarize: There were problems with the backup/restore functionality and this was partially resolved by increasing some PHP settings. This would work when user enrollment data was not selected and may sometimes work when it is selected, and I am looking to get this to work entirely with user enrollment data included in these backups.
I have examined certain database tables that (I assume) go in to these backups and while size limits are not a factor, variable counts likely are a factor that would affect these backups. I could try to increase php_max_input_vars but I've read elsewhere that doing so could included security risks, which I'd like to avoid.
If anyone can help out please let me know.
Thank you in advance.
