Backup task taking the incorrect source disk

[mohankrajan]

My task backs up my C: system drive to Drive X.
I replaced my System Disk for a new SSD.
Now when the backup task ran, it incorrectly backed up another drive Y instead of the new C drive.
I had to delete the task and create a new Task.
Is this behaviour expected?
do i need to delete all backup tasks each time I change drive letters or change disks?
