Probably yes, though I have never tried this. This would mean that your disks ie. the raid has to be rebuild each time you reconnect the disks. - From my experience this is a rather time consuming. You also get a problem, if for some reason you modify both disks independently. (Say you quickly edit some stuff on A while the second disk is attached to B or unplugged). > 2. Where should I start? > 3. Any other issues I haven't thought of (I have zero experience with > RAID) I'd suggest using unison or some other application to keep both disks in sync. unison is rather fast at syncing the disks and even has some capabilities of merging (mainly usefull for text files) in case you modify your files on both replicas in between two runs of unison. Effectively you will always have one 'offline' backup: either the external disk (when working on the home laptop) or the laptop at home (when working with the external disk).
