RAID 1 & Partitioning

[babylonlarry]

Am considering getting a Lacie 2 big dock T3 drive which I would use to back up an iMac and a MBP. Are there any complications with a plan to have back up partitions with Time machine and CCC folders for each machine and a third storage partition?

The 12 TB Lacie with dock looks good giving 6 TB with full redundancy. The MBP is thunderbolt 2 so would need an adapter. Problems there? I tried to read a drive in target mode with an aftermarket T2-T3 adapter and it didn't work.

I've had back up external HDDs fail. A Lacie Porsche has just failed to power up and am waiting for response to a ticket, so want to avoid losing both back up data and media files stored externally in the future.

Don't think I want to count on connectivity to use cloud for back up, but other concepts welcome. TIA Larry

I know you’ve got some redundancy for a single disk fail with the RAID array, but personally I would not keep both your Time Machine and your CCC backups for all your Mac on the same device. In case of some hardware failure / accident / theft of the device itself you lose all your backups across all your macs...
Also you’ll need a backup strategy for the third storage partition, can you chain a USB device off it for example?

My intention for BU security is to have the iMac back up to a partition of the RAID array in RAID 1. The MBP backs up to a Rugged USB 3.0(A type). I do not know whether I can do RAID 1 on a BU parition, while doing RAID 0 on a data partition that will be duplicated on the Rugged portable. I am currently backing up the iMac to a Porsche desktop USB 3.0. The porsche will become a media storage drive, and could have a partition to duplicate CCC of both macs.

If I upload disk images of both machines to cloud storage, periodically updating the image, I should have good recovery options(?)
