Drive backup task corrupted on updtate

Hi. First post!

I have used a DS918+ for years now with no problems. However I just had an auto update of Synology Drive occur. It seems to have erased all of my backup tasks. All files, mainly photos, are still on the ÑAS but there is no associated task to continue the backup. I can see no settings that allow me to recreate this task.

So do I need to start again? What will happen if I recreate the same task? Will it override the existing files or bypass those that are already there?

Hep please!
