how to keep in sync two external hard drives – backup – mac os x
Dear all,
I’d like to backup an external drive the way Time Machine does with the computer’s internal drive yet I couldn’t find any unambiguous information on this. I have 2 external hard drives – 1TB one – sort of internal drive extension – containing data I work on everyday and thus keep changing its structure. The other one is 2TB drive which I bought for backup purposes and so I would like to keep the two in sync somehow. Is there any software I could use?
Thank You in advance
Pawel
