Well, that was interesting.
I logged in to Liz’s account to back up her home directory to my Lacie portable drive.
While there, I thought, “Let’s see if Time Machine will back up to the Time Capsule from here.”
Apparently, it did. Although it reported the copying stopped with an error, it was a different error than the one I’ve been seeing in my account. But the backup was marked as complete and verified.
So – we have a Time Machine backup! Getting one was a top priority, though I thought it would happen on the new external drive first.
(I bought an external drive yesterday but have not unboxed and plugged it in yet. Life. Don’t talk to me about Life.)
The lesson here may be that my account has too much cruft, both on disk and in RAM, that hinders an effective TM backup. My account is due for a scrub-up: deleting unused apps and Library subfolders, mainly. But it’s total guesswork whether this would do any good; magical thinking, more like.
Tonight, I purchased a two-year subscription to Backblaze and installed it. It’s got a more Mac-like UI than Crashplan did and started immediately. I like its default settings so far. It is backing up files as I type.
To be continued!
