Survival Kit vs. Bootable Media

Thread solved

I have two Macbooks to back up.

Silly question alert: I assume you can't create two separate Survival Kits for two different Macs on one removable drive?

I'm fairly sure you can't, but just wanted to double check before I start backing up.

I think separate bootable media on flash drives, with the backups on external drives, will work better for me as it will allow me to use the hardware I already have.

I need two physical backups (one off-site) because my internet connection doesn't allow me to use cloud backup unfortunately. A separate Survival Kit for each mac would therefore require four external drives, each with enough space to hold the backups.

However, separate bootable media on flash drives (which I have plenty of lying around), would allow me to backup both Macs to two external drives, used in rotation, with one kept off site (I already own two drives with enough storage to hold full backups of both computers).

That probably seems obvious to most people, but I'm just sense-checking it, not having used True Image before.

Thanks

David, first a statement that I am not a Mac user, so my further comments are given from a Windows user perspective!

There should be no need to have separate Survival Kits for your two different Mac computers provided that when you test booting from the Survival Kit you are able to see the disk drives in those computers without any issue.

The Survival Kit process won't allow you to create separate versions on the same drive as far as I understand but this should not be needed.

I would recommend having your separate bootable media for each computer alongside having the survival kit drive. Never hurts to have 'belt & braces' in my opinion.

Steve, thanks for the useful response. So yeah, belt and braces - I agree. What I have done is: 

- Created two Survivial Kits for my mac, one on each of my 1TB exernal drives, which will be updated in rotation with one being kept off site 

- Aslo performed a full backup of my parter's mac onto each of the two 1TB drives

- Also created a couple bootable media flash drives for my partner's mac (her mac should boot from my Survivial kits if necessary, but just in case it doesn't)

So now we have on site and off site backups and bootable media for both computers; and no need to buy extra hardware. 

[if where I live ever joins the 21st Century and gets a sensible internet connection, then I'll replicate to the cloud, but in the meantime I think this solution works]

Thanks.

David, thanks for the update and good to hear of your progress with this topic.
