Size of bootable external disk
 
Would anyone be able to tell me for sure if it's OK to have a bootable backup disk smaller than the disk it's backing up - assuming of course that the amount of data on the main disk is significantaly smaller than the size of the bootable disk.

The reason I'm asking is because I need to buy a backup disk for my laptop that has a 60 GB disk. However, I also want to be able to use the new disk to back up my next laptop that I expect, by the time I purchase it (in a year or two), might have a disk 250 GB or larger. I don't really want to buy a 500 GB disk so I want to check that if I buy a 250 GB disk and end up buying a laptop in a couple of years time with, say, a 320 GB disk, I will still be able to use the smaller external disk as a bootable backup. (I don't put anything on my laptop apart from business files which are all quite small so wouldn't expect to get anywhere near 250 GB).

Thanks

Yes, as long as your data fits on it with about 20% free space (so the OS has room to work), it should be fine.

Thanks, that's good to know.
