Time machine backup using memory cards

[craigjm]

I am wondering whether it would work to buy a hub adaptor like this -

Then use one of the memory cards as the macbooks main storage and use time machine to back up to the other memory card

Any reason why not?

Read/write speed?

No-one has ever touted memory cards as reliable long term storage medium?

I don’t need it for long term I’m not expecting to survive a nuclear attack here all I want to be able to do a basic backup for the next 12 months and as I needed a HDMI port I thought this might be a quick and easy solution.

12 months is long term & memory cards do not last forever with repeated read/writes. There's a reason you dump the data off them on to another storage medium.

Anyway, your call.

Absolutely. I’m willing to take that risk. What I am asking in the question is whether time machine can be set up to do it backing up one off oars device to another in effect. I know the risks of data security etc and don’t need to go down that route here.
