Magento2: Rolled back db now i can't backup

[zamboni084]

Hi

I rollback my db and now when i try to run a backup from admin it does not work.There is also no list of backups on the backup page(System>Backups)

I enter a name for the backup and click ok and nothing happens.

Browser console i get.

TypeError: this.modal.find(...).validation is not a function
this.modal.find('#backup-form').validation({

Thanks

I'm seeing the same error but on a fresh install.

This error occurs in development and production mode on multiple servers, apache and nginx.

Hi there,

we have exact the same problem when trying to backup.

Did you find a solution for this?

I have 2.0.7; I can no longer backup. Button does nothing. Also have the same JS error. I used to be able to backup.. I do not know when it stopped working from 2.0.1 to 2.0.7

I have this error in my browser console:
Uncaught TypeError: this.modal.find(...).validation is not a functionAdminBackup.backupConfig.backup-options.actionOk @ backup.js:148modal.jQuery.attr.html.modal.buttons.click @ backup.js:205jQuery.event.dispatch @ jquery.js:4624elemData.handle @ jquery.js:4292

I have 2.0.7 and I am experiencing the same problem that flnative has reported. I see the same error in Chrome Developer tools. The backup button does nothing and the backups page does not show a list of backups that are in the var/backups folder.

I am experiencing the same issue on a 2.3.3 installation.

[Update]
Tried to upgrade to 2.3.5 still not working

I seen a exception which only happens in developer mode when initially loading the backups screen in admin which related to the files in var/backups. I had put some manual backups in there M2 didn't like. So I removed these and WALAA. It works.
