rsync two existing folders!

[smilenkovski]

Hello everybody.

I have three xpenology nas's. One using, two for backups. I ususally make backups with rsync from file services. But, the other day I've had  to reinstall dsm and lost task. There is procedure to make new task with renaming folders etc (to conitnue using rsync on same folder). To much juggling. Same with Hyper Backup.

Finally, my question, Is there any app to sync two existing folders without changing the folder structure, renaming and after the any failure just to continue syncing. I am talking about app which I will use weekly on demand. I'm turning on backups ones per week.
