In case someone at Backblaze is reading this : I had a less than ideal experience in the past couple of days, trying to report through normal support channels a potentially critical bug breaking the "inherit backup" feature in the Mac client.<p>Here goes : a few days ago the Backblaze Mac client started prompting me to upgrade urgently to the latest version (6.1.0.370). I went ahead and did that but got "Installation could not complete, please contact support" each time. Support advised me to wipe /Library/Backblaze* , reinstall, then inherit the existing backup.<p>Well, we never managed to get the inherit process to complete : it failed with "ERR_error_unknown" every time. And I started freaking out.<p>That's where things get interesting : I became frustrated with the canned responses from support and decided to delve into the client logs myself. I quickly found a potential smoking gun (in bzbmenu.log) : a spelling mismatch in an XML attribute name between the server response (support_inherit="true") and what the client was expecting ("ERROR could not read attribute named supports_inherit"). Notice the extra "s" ? Pretty obvious typo and one that could definitely explain the failure (client can't confirm that the selected backup is eligible for inheritance, bails out)<p>I was rather happy with my findings and shared them in plenty of details with support (including log excerpts), but instead of a "thank you and here's some free months of service !" response, I got "meh, this log file is irrelevant", and worse: no promise to escalate the issue (until I insisted a second time). They suggested updating to the 6.1.0.372 beta, which turned out to have the exact same bug.<p>Now, I'm left wondering if should try upgrading to 7.0 and inheriting my 6.1 backup from there. But the point of this message is to share my disappointment with this support experience. I went out of my way as a customer and spent a couple of hours researching and finding something potentially useful to the company, but had no appropriate way to report it. I even tried security contacts, but was (rightfully) told it wasn't a security issue. No word on whether they were going to pass it on to the relevant team.<p>EDIT: I've just confirmed that the same issue is present in 7.0.0.386. Still can't inherit my existing backup.
