If you can mount your SSD into a USB external case or SATA to USB cable harness you can clone your current SSD (or HD) over to it.
Doing it that way you don't really need a backup as your current SSD (or HD) will be your backup.
You can even use the Boot Disk preference setting to test out your SSD before you open the system to exchange out the drives.
Normal backup should be fine. You'll have to boot from an install disk to format the new drive, install the OS and then use Migration Assistant (in the Utilities folder in Launchpad) to restore information to a new computer or HD/SSD.
