Thank you John & Carlos,

I sounds like I'll just stay with using rsync for now

I'm pretty sure there is but I'm asking to make sure ..

I have a live system on sda and currently using rsync to backup to sdb
(identical size disk).

Notice that your current procedure is safer than raid.

Also all partitions - including root and boot - are running reiserfs

Can I add RAID 1 on the fly without disturbing my live system ?

I can think of a method, but I can not guarantee that it works.

First you create a degraded raid 1 on the second disk. You copy everything there. Then you repartition the first as raid, and add it. Suggest you create a virtual machine to develop the procedure. Much safer to create a full backup and reinstall.
