I'm being provided with two individual external hard drives to accomplish a backup of a large internal drive. Each external drive is independently too small for the job, but together their space is sufficient. I can format them however I want and do anything I want with them.
Can Time Machine perform a single backup that is split across two devices, simply writing to one device until it runs out of space and then writing to the second? If not, can I create a RAID 0 array out of two independent external drives? What would recovery look like if I had to restore such a backup from scratch to a new HDD?

Thx
 
No. You will need to either get a larger drive or exclude certain files from the backup.

Unfortunately, I don't have any experience with using Time Machine on RAID arrays. However, using RAID0 as a backup target seems to defeat the purpose of having a backup.
