backup conundrum

[humberhull]

Hi

I need some really basic advice. Im operating an iMAC with OS 10.5.8. I want to update my OS. But first I want to backup my computer in case I lose anything because of the update (should do this anyway, I know). So I bought a time capsule. The time capsule requires OS 10.7.5 or later....

So you see my problem? All advice much appreciated -

HH

Hi and welcome,

Possible get a external HD it only needs to be say 500GB so will be very cheap. Then run a time machine backup. Once completed you can upgrade to SL after which you can use your new TC and use the external for file storage or what ever.
