I just purchased one of the newly updated 27" iMacs. I also have a MacBook Pro which I will still be using for working on the road or any time I want to work somewhere not at my desk.
I have been backing up my MacBook Pro to Time Machine, a bootable CCC clone, and Backblaze. The new iMac will get the same CCC and TM treatment, of course, and Backblaze for offsite.
My question is: Do I continue to back up the MacBook Pro to Backblaze, or do I just transfer the license to the iMac?
The iMac will be my primary machine, and there will be very little that is unique on either machine; they’ll largely have the same files. If anything, it is the iMac that will have unique files since it has more storage than the MacBook Pro (e.g., I’ll have my entire iCloud Photo Library on the iMac but probably run the MacBook Pro as Optimized, from here on out).
So the question is: Having BackBlaze on both machines doubles my BackBlaze costs, but does it meaningfully reduce the risk of data loss? I am leaning towards thinking that it does not reduce the risk of data loss to a degree that justifies doubling my cost for the following reasons:
- I will be doing probably 75% of my work on my iMac. The number of totally new files I generate on my MacBook Pro will therefore be comparatively small.
- The VAST majority of my files are synchronized between machines (using iCloud, Dropbox, or Github). Anything novel that I create on the MacBook Pro will get synced to the iMac and backed up to BackBlaze from there.
- Anything I create on the MacBook Pro that isn’t also part of a sync service will likely be moved to the iMac at the next opportunity.
The possible risks to only having the iMac backed up to BackBlaze:
- I have a novel file or heavily modified file on my MacBook Pro that doesn’t get synced for some reason (service is down, no internet connection, etc), and which is lost/damaged, or the computer is lost/damaged.
This is a fairly unlikely scenario, and the most likely circumstance this scenario would occur would be when I don’t have an internet connection (rather than a failure of a sync service), in which case BackBlaze would also not help.
- My iMac is rendered unavailable for some reason (power/internet outage at home that it never recovers from) and doesn’t received synced files, and my MacBook Pro fails.
While this is a bit of an unlikely scenario, it is one that would actually be protected against by having BackBlaze available on my MacBook Pro.
Nevertheless, I’m leaning towards just having BackBlaze on my iMac, and not on my MBP. Convince me otherwise!
(I understand that, ideally, both would have BackBlaze, but I’m a bit budget sensitive at the moment and so any place I can avoid introducing new costs is helpful.)
